September is Ovarian Cancer Awareness Month

September is Ovarian Cancer Awareness MonthSeptember is Ovarian Cancer Awareness Month. As one of the most deadly cancers, it is crucial to raise awareness and increase patient education about ovarian cancer. As there is no test for ovarian cancer, recognizing the symptoms and being diagnosed early are critical to saving lives.

Ovarian cancer symptoms are often subtle and difficult to diagnose. However, some symptoms of ovarian cancer can include: 

  • Bloating
  • Pelvic or Abdominal pain
  • Difficulty eating or feeling full quickly
  • Urinary urgency or frequency

Other symptoms may include:

  • Nausea, indigestion, gas, constipation or diarrhea
  • Extreme fatigue
  • Shortness of breath
  • Backaches

Talk to your doctor if symptoms last more than 2-3 weeks. You are your best advocate!

Ovarian cancer does not discriminate. It can strike a woman of any race or at any age. Women with certain risk factors may have a greater chance of developing ovarian cancer. These risk factors include:

  • Family history of breast or ovarian cancer
  • Personal history of cancer
  • Women over the age of 55
  • Women who were never pregnant
  • Women on menopausal hormone replacement therapy

Spreading the word about the symptoms can help save lives. It is our goal to promote awareness and early detection of ovarian cancer through advocacy and education, while providing support to people affected by ovarian cancer.

Orthopedics and Radiology: An Effective Pairing

Orthopedics and Radiology: An Effective PairingOrthopedics and radiology are separate specialties. Orthopedics focuses on diagnosing and treating issues with the musculoskeletal system: bones, tendons, joints, muscles, nerves and how they all fit together. Radiology specializes in diagnosing and treating illnesses and injuries using a variety of medical imaging techniques and radiation.

These two specialties are incredibly effective when used together in the diagnosis and treatment of a wide variety of conditions. For instance, when evaluating a patient with osteoarthritis, a radiologist can see exactly what is going on inside the affected joints; and the orthopedist can prescribe treatments based on the imaging results.

Radiology and orthopedics cooperate to diagnose and treat many other conditions, including:

  • Broken bones: radiology provides clear images of the break and allows the orthopedist to plan the most effective way to realign and support the healing of the injury.

  • Spinal problems: spinal injuries, broken vertebrae, spinal degeneration and deformities are clearly displayed using diagnostic imaging. This guides the orthopedic treatment team in designing and carrying out the most effective treatments, which can include surgery, braces and physical therapy.

  • Sports injuries: sports injuries are common, and diagnostic imaging allows for accurate diagnosis and treatment planning.

  • Tendon and ligament injuries: tendons and ligaments can be torn or strained in falls, sports and work-related injuries. Radiology clearly shows the extent and precise placement of the injury so that the orthopedist can plan the most effective course of therapy, surgery or other treatments.

  • Congenital deformities: many congenital deformities affect children; the entire field of orthopedics was founded by a physician who wanted to help these children. Diagnostic imaging provided by a radiologist provides clear pictures of what exactly is going on in the body and helps the orthopedist diagnose and plan treatment.

  • Evaluation of joint degeneration: Hip, knee and shoulder degeneration is very common; repairing and replacing damaged and degenerated joints are some of the most frequent orthopedic surgeries. Radiology guides the orthopedist in planning treatment.

PET Scan vs. CT Scan: What’s the Difference?

PET Scan vs. CT Scan: What's the Difference?Your doctor decides to order a test to rule out certain brain disorders in light of your all-too-frequent severe headaches. Which test is he more likely to order, a PET scan or a CT scan? Making sense of current technology can be confusing, given how many different ways radiologists can look inside the human body to detect problems and monitor existing conditions and treatments.

PET Scan

A PET (positron emission tomography) scan is an imaging test that uses radiation to allow a doctor of radiology to check for diseases in your body. A PET scan produces 3-D colored images and involves the use of a special dye containing radioactive tracers. When these tracers are highlighted under a PET scanner, they allow the radiologist to not only see your organs and tissues, but also to see how well they are functioning. A PET scan can measure vital processes such as blood flow, how efficiently your body is using glucose, oxygen use, and more.

PET scans are most commonly used to detect conditions and disease processes including:

  • cancer

  • heart problems

  • brain disorders

  • CNS (central nervous system) problems

  • epilepsy

PET scans are also used to monitor how a condition is progressing or how effective the ongoing treatment of a condition is. Unlike a CT scan, a PET scan shows problems at the cellular level. PET scans are often used along with CT scans, X-rays or MRI scans to obtain not only an image, but also a clear idea of how tissue and organs are functioning in real time.

CT Scan

The “CT” in CT scan stands for computed tomography. It uses special X-ray equipment to help detect a variety of conditions and diseases by producing multiple cross-sectional pictures of the inside of the body. These images can then be reformatted in several planes, even to the point of creating a three-dimensional image of a part of the body. The radiologist can view these images on a computer monitor and transfer them to film, a CD or a DVD. The images produced by a CT scan provide greater detail than the images produced by standard X-rays.

Because these images are produced so quickly, CT scans are often used in emergency situations when a fast diagnosis can literally save a life. They’re often used to look inside the chest, abdomen and pelvis because they provide detailed, cross-sectional views of all types of tissue. In addition to being the test of choice for emergencies, CT scans are also routinely used for diagnosis of:

  • tumors

  • vascular diseases and aneurysms (both pulmonary and aortic)

  • spinal problems

  • skeletal problems (showing even very small bones and surrounding tissue and muscles)

A CT scan is also a helpful tool for:

  • guiding biopsies

  • planning for surgery

  • planning and guiding radiation treatments

  • monitoring a patient’s response to chemotherapy

In some CT scans, a contrast dye is used to enhance visibility of the part of the body being examined.

If you would like to request a PET scan or a CT scan, please contact us at Peninsula Radiology Associates at (757) 989-8830. We have served the Virginia Peninsula for more than 50 years with a well-earned reputation for state-of-the-art equipment, expertise and compassion.

Lung Cancer Screenings

lung cancer screenings

lung cancer screeningsIt is important to know that there are benefits to any screening, including lung cancer screenings. Benefits of lung cancer screening include:

  • Survival: Early diagnosis makes treatment more effective. Perhaps the main benefit to lung cancer screening is that lung cancer is caught early is more likely to be treatable and cured.

  • Research advances: Higher risk patients who are screened early may be offered new advancements in treatment.

The Screening Test

Lung cancer screening is performed using an imaging machine to produce a low-dose spiral (or helical) CT (Computed Tomography) scan of the chest. This scan uses a series of x-rays to show the shape, size and location of anything abnormal in the chest that might signal the need for follow up. CT scans are very sensitive and can show both cancerous and noncancerous areas.

During a CT scan, you will lie very still on a table, which is slowly moves through the CT scanner. An x-ray machine rotates around you and takes pictures from many angles. A computer then combines the pictures into a very detailed image. There are no medications or injections needed and there is no need to stop eating or drinking before the exam. You may be asked to hold your breath for several seconds. That way, your lungs will not move during the scan and the images will be clear.

The Results

The results from your lung cancer scan will be sent to the doctor who referred you for screening. Your doctor will review the results of the scan and will discuss them with you. Because a spiral CT scan is so detailed, it is possible that something will show up on the exam that is not cancer. Your doctor will discuss the best way to follow up on any test result.

If you have any questions or concern about lung cancer screenings, please contact Peninsula Radiology Associates at one of our locations.

Interventional Oncology: The Facts

interventional oncology

interventional oncology

Peninsula Radiology Associates has a patient-focused and caring team of providers at its Center for Interventional Oncology, trained to give you the very best care. You may wonder, what is interventional oncology? What kinds of cancer does it treat? Why should I consider getting screened if I have no symptoms? Read on to get the facts about interventional oncology.

What is interventional oncology?

Interventional oncology is a specialized branch of medicine enabling the diagnosis and treatment of certain cancers by using image-guided procedures. It utilizes imaging techniques, including X-ray, ultrasound, CT and MRI scans. Despite the term “interventional,” interventional oncology procedures are actually minimally invasive and obviate the need for more invasive surgical procedures.

What types of cancer is interventional oncology used for?

Interventional oncology has many applications. Doctors may use interventional oncology to diagnose and treat cancers of the liver, lung, kidney, bone, breast, ovaries, prostate and pancreas.

Why is early detection so important?

Early detection of cancer is important because it saves lives. The sooner cancer is found, a patient’s chances of survival increase dramatically. Interventional oncology plays a vital role in early detection. Even if a patient is not experiencing symptoms, if he or she is at risk for certain cancers, the treating physician may recommend interventional oncology tests.

Doctors throughout the Peninsula rely on us, partnering with the Riverside Health System, to provide them with extremely accurate test results — and our patients love our patient-centered philosophy. Please contact us at (757) 989-8830 to set up an appointment at Peninsula Radiology Associates at one of our seven locations.

Brain Imaging Techniques: How Youth Sports-Related Concussions Are Evaluated

brain imagingOur team at Peninsula Radiology Associates is pleased to present this article on concussions, particularly for its timeliness. As you know, scientific findings show that too many concussions sustained repeatedly from falls or collisions (as in pro football) may result later in brain damage, confusion, depression, aggression and early dementia.

If you have a child, middle-school or high-school-aged family member playing sports, and you suspect your loved one has sustained a concussion, it’s important to go to your family doctor or urgent care center immediately. Your doctor will most likely emphasize the importance of brain imaging to his diagnosis and treatment.

In the event of a mild concussion, sometimes referred to as mTBI or mild Traumatic Brain Injury, a physician or emergency room personnel will evaluate your loved one’s symptoms and decide whether a CT scan or MRI for brain imaging will be needed. You will want to get your child’s brain imaged as soon as possible, since the effects of sport-related concussions (SRCs) on the developing brains of pre-high-school-aged athletes are not well understood.

Immediately after injury

If a patient is brought in soon after an injury occurs, a CT scan will likely be chosen to rule out a more serious concussion. CT scans can show acute injuries like hematoma (bleeding in or around the brain), edema (swelling of the brain) or a skull fracture. When a concussion is mild, the CT scan often comes back as normal. If a patient is not feeling well, a CT scan is easier and faster to perform as well as less costly for parents.

Two days after injury

If the concussion happened more than 48 hours ago, an MRI is a more likely choice. An MRI will show details that would not show up in a CT scan. This type of scan is better at showing even tiny injuries to the brain, such as small contusions (bruises), micro-hemorrhages (small areas of bleeding) or signs of microscopic damage to nerve fibers. These small changes in the brain are what doctors want to check for when a patient has not recovered as quickly as expected or has worsening symptoms.

An older concussion

If an injury occurred a long time ago, physicians use either CT or MRI to look for brain atrophy, when brain tissue is injured or dead and the surrounding tissue begins to absorb it. This changes the physical structure of the brain over time.

Most patients with a mild concussion will fully recover in a short amount of time. When parents or physicians see that a child has continuing headaches, poor balance, difficulty in thinking or other symptoms that don’t go away, another brain imaging scan, either CT or MRI, will be ordered. If a scan shows a structural change in the patient’s brain, such as atrophy, the physician will know more about how to proceed and help the patient recover.

Every young athlete’s SRC is different, and every concussion will result in a range of symptoms. If you or a loved one needs an appointment for brain imaging at one of our seven convenient Peninsula Radiology locations, please call (757) 989-8830 to schedule. 

What Is Breast-Specific Gamma Imaging?

Nuclear Medicine breast specific gammaIf you’ve recently had a mammogram that detected a growth or was inconclusive, you’ve probably already heard about breast-specific gamma imaging (BSGI); or molecular breast imaging (MBI), as it’s sometimes called. Our nuclear medicine and radiology experts at Peninsula Radiology Associates, while acknowledging the lifesaving value of mammography, want to familiarize you with the unique diagnostic value of BSGI testing, as well.
Why You May Need Breast-Specific Gamma Imaging After Your Mammogram

Breast-specific gamma imaging allows doctors a closer, clearer look when a mammogram has detected cancer or its findings are inconclusive (which sometimes happens when a woman’s breast tissue is especially dense). The BSGI test is used to detect:

  • Additional lesions missed by a physical exam and mammography.
  • An abnormality or a mass requiring biopsy.
  • Cancers which are not always detectable by mammography.

Breast-specific gamma imaging, known in nuclear medicine as Scintimammography, uses a small amount of radioactive material which enables doctors to pinpoint molecular activity within the breast, improving the chances of both identifying disease in its earliest stages as well as assessing a patient’s responses to treatment that is already underway.
What Does the BSGI Procedure Involve?

BSGI is non-invasive and involves being injected with a radiotracer (a drug that emits radioactivity). This radiotracer accumulates in different ways in various types of tissue. The doctor uses a device known as a gamma camera to detect the gamma rays given off by the radiotracer as it accumulates in the breast tissue. This lets the doctor know if cancer might be present and whether a biopsy or other type of follow up procedure is needed.

The test itself doesn’t actually feel much different from a mammogram, and in fact the two machines look somewhat similar. You’ll wear a hospital gown for the test, just as you would for a mammogram. The only differences are the injection of the radiotracer and the use of a gamma camera against the compressed breast.

When You Receive Your BSGI Results

It’s important to know that even if a mass within your breast is confirmed by a BSGI test, and a biopsy is ordered, this doesn’t necessarily confirm a cancer diagnosis. Both malignant and benign tumors appear the same way. The BSGI only confirms the presence or lack of a mass in the breast; a biopsy reveals precancerous or cancerous cells.
If your doctor advises you that you should have a BSGI, Peninsula Radiology Associates, serving five Hampton Roads locations, is easy to find and known for its compassionate, experienced doctors and technicians. Please contact us at (757) 989-8830 to schedule an appointment at the most convenient location for you or your loved one or to learn more about our many services.

What is Nuclear Medicine and How is It Used?

nuclear medicine radiologist Newport News VANuclear medicine is a global term used to describe a form of medical imaging that relies on the use of trace amounts of radioactive materials to aid in the imaging of the human body.

What Is a Radiotracer?

The amount of radioactive materials, commonly referred to as a ‘radiotracer’, is extremely small and should pose no medical risk or radiation exposure risk to the patient.

The purpose of the radiotracer is to allow medical imaging systems to easily image certain types of tissue. Radiotracers emit miniscule amounts of gamma radiation, which is easily detected by special medical imaging equipment. Cameras and computers can use the radiation to create an accurate image of the area in which the radiotracer is concentrated.

Advantages of Nuclear Medicine as a Real-Time Diagnostic Tool

Nuclear medicine has a number of advantages over other imaging techniques. For instance, since the material containing the radiotracer can be ingested, it can allow for a detailed imaging study of the gastrointestinal or renal system as the material is processed by the body. For this reason, nuclear medicine is commonly used as a diagnostic tool for gastrointestinal disorders and renal function studies.

Radiotracers can be introduced to the patient’s body in several ways. The three most common ways are: injected, inhaled as a gas or swallowed.The actual trace material only makes up a very small amount of the material that is introduced into the patient’s body. The majority of the material swallowed, injected or inhaled is simply used to transport the material into the body.

Once the patient has taken the radiotracer into his body, the next step is the actual imaging process. In most cases, this process, involving a special camera, is a relatively quick, simple process.

No Risk of Long-Term Radiation

Afterwards, a patient’s body naturally expels the radiotracers. Nuclear medicine used in medical imaging carries no risk of long-term radiation exposure.

Images obtained through this process may be later combined or studied side-by-side with images obtained through other imaging techniques, such as MRI (magnetic resonance imaging).

Nuclear medicine is a safe, powerful diagnostic tool your doctor can use to diagnose and treat many common conditions that would not be as easily treatable — or detectable — without the use of nuclear medicine.

The History of MRI: From Nikola Tesla to Modern Miracle

MRI Newport News, VAIf you are a child of the 1980s or subsequent decades, it probably seems to you that doctors have been ordering MRIs since the beginning of time. It’s hard to imagine a period when this diagnostic option didn’t exist for physicians and patients.

At Peninsula Radiology Associates, we thought it would be interesting to give you a quick rundown on how this means of spotting diseases of the central nervous system and soft-tissue injuries in muscles and ligaments came to be.

Back in 1882, the famous and versatile inventor Nikola Tesla made a groundbreaking discovery in physics in Budapest, known as the Rotating Magnetic Field. In the 1950s, Herman Carr created a one-dimensional Magnetic Resonance image. In 1956, the “Tesla Unit” was proclaimed in Munich, Germany, measuring the strength of a magnetic field. Stronger magnetic fields correlate with a stronger number of radio signals derived from the human body’s atoms, resulting in higher-quality MRI images.

A scientist at New York’s Downstate Medical Center named Raymond Damadian discovered that the hydrogen signal in cancerous tissue differed from that of healthy tissue, as tumors contain more water. As we learn in chemistry, more water contains more hydrogen atoms. Damadian noted that when the so-called nuclear magnetic resonance was switched off, radio waves emitted from cancerous tissue lingered longer than those of radio waves from healthy tissue.

In 1973, close on Damadian’s heels, chemist Paul Lauterbur produced the first Nuclear Magnetic Resonance image, of a test tube! In 2003, Lauterbur would receive a Nobel Prize for affording physicians the capability of looking inside the human body without using harmful radiation.

But Damadian, too, was onto something and by July 3, 1977, assisted by two post-doctoral students, he hand-built the first Magnetic Resonance scanner, which he proudly named the “Indomitable.” In 1977, he and his students performed the first MRI scan of a healthy human body; and in 1978 the team had taken the first MRI of a human body affected by cancer.

The first MRI instruments became available in the early 1980s, when, according to an magnetic-resonance imaging journal, “there were 12 [MRI] machines, and everybody working with Magnetic Resonance imaging knew each other.” As of 2016, 36,000 MRI scanners existed worldwide, with approximately 11,500 of the machines in the United States.

In 1987, real progress on the capacities of Magnetic Resonance imaging continued: real-time MR imaging of the heart was developed. By 1994, functional MRI had been discovered to provide real-time information on brain activity and function and by 2000 was widely used to guide neurosurgeons.

While in the1990s MRI had been reserved mainly for neuroimaging and musculoskeletal imaging, by the millennium, Cardiac MRI, Body MRI, fetal imaging and functional MRI had been further refined and were performed routinely at imaging centers.

Peninsula Radiology Associates hopes you have enjoyed this glimpse into the discovery and development of a technology we are proud to use daily.
