A CT scan stands for a computed tomography which scans the abdominal and pelvis which provides diagnostic image testing that will help detect diseases in the small bowel, colon, and many other internal organs in the same region. CT Scans are generally used to determine the cause of unexplained causes of pain.
Are CT Scans Safe?
CT Scans to expose you, very briefly, to a very small amount of ionizing radiation, however it is necessary to help recreate the structures such as organs in the body to determine the cause of the unexplained pain. The tiny amount of radiation that you are exposed to is so small that the increased risks of cancer the person is exposed to cannot even be reliably measured.
When Are CT Scans Done?
CT Scans are often done after the body sustains traumas such as that from a car wreck, work accident, or other traumatic event like a sports injury. These scans will take images of the various parts of the body including cross-sectional images of the body to see if trauma or injury was sustained.
CT Scans are then used to determine plans of treatments, surgeries, or radiation treatments that may need to be completed to help treat the trauma or the issue. These treatment plans can help the patient get rid of the pain and
What Conditions to CT Scans Help Reveal?
CT Scans can help determine some of the following:
Diagnose muscle and bone issues such as tumors or fractures
Pinpoints various procedures that the patient may need such as a biopsy or if they have something more serious like an infection or blood clot
Detection and monitoring of longer-term diseases such as heart diseases or cancers.
Monitor the effectiveness of ongoing treatments such as radiation or chemotherapy treatment.
Helps detect internal injuries such as bleeding or injuries and internal trauma that was done to the organs.
Talk to your doctor if you are pregnant. While the miniscule amount of radiation from a CT Scan is unlikely to harm an unborn baby your doctor may prefer to use other imaging, such as MRIs or ultrasounds just to be safe.

At Peninsula Radiology Associates, one of the procedures our interventional radiologists rely upon to properly diagnose and treat patients is called fluoroscopy. We use it many times daily in taking care of patients referred to us for radiologic testing and procedures.
What Is Fluoroscopy?
Fluoroscopy is a vitally important imaging technique used to track the progress of a contrast dye. It is a form of diagnostic radiology that allows moving body structures to be examined via X-ray through the use of fluoroscope and a contrast agent. For doctors and technicians, its images are constantly viewed on a monitor as a kind of moving X-ray.
Fluoroscopic exams are used as diagnostic tools for a number of common medical problems. Some of its uses include:
- To visualize gastrointestinal issues, a patient may be asked to swallow barium, or a similar contrast material. Once the barium has been ingested, an imaging technician uses fluoroscopy to track the progress of the barium through the patient’s system or pain areas and spot potential problems in real time.
- In placing cardiac stents and inserting and manipulating catheters for embolization — stopping excessive or traumatic blood flow — and other procedures, physicians rely on fluoroscopy to see exactly where to place them and verify they have been properly placed.
- Cardiac physicians utilize fluoroscopy to obtain precise images of the heart, veins, and arteries. They also use it to spot potential trouble areas, including narrowed blood vessels and arterial blockages.
- Some other indications for fluoroscopy exams include: small bowel series; barium enemas; hysterosalpingograms; intravenous pyelograms; voiding cystourethrography; myelograms; arthrograms; biopsies; lumbar punctures; facet injections; orthopedic procedures (such as manipulation of broken bones in fracture reduction); and insertion of implants and checking appropriate position and realignment.
What To Expect During a Fluoroscopy Procedure?
The contrast agent — which allows the image to be viewed when x-rayed — will be introduced into the body via swallowing, injection, or an enema.
- In general, you will be asked to lie or stand between an X-ray machine and a fluorescent screen after putting on a hospital gown.
- An intravenous (IV) line may be started in your arm; or a catheter may be inserted.
- An X-ray scanner produces fluoroscopic images of the body part being examined.
- The procedure itself is generally painless.
The Benefits of Fluoroscopy
Fluoroscopy causes very little risk to patients. The amount of radiation exposure in fluoroscopy is quite minimal.
Additionally, using fluoroscopy is much safer than attempting the multiple procedures in which it is used without its value of real-time, moving images for physicians and technicians. For example, attempting to place a cardiac stent without fluoroscopy would be very risky to the patient, and the procedure would take much longer.
Fluoroscopic equipment and safety measures help reduce the risks associated with the procedure by incorporating:
- Increased X-ray filtration to reduce the possibility of radiation injuries during long procedures
- Displays of the duration, rate, and cumulative amount of radiation exposure patients receive
- Tighter controls on the size of the X-ray field to reduce the amount of radiation that falls outside the image target area

Season’s Greetings and Happy Holidays from our family to yours, at Peninsula Radiology!
The International Day of Radiology is building greater awareness of the value that radiology research, diagnosis and treatment contribute to safe patient care, and better understanding of the vital role radiologists perform in healthcare delivery. November 8, 2017 marks the sixth annual International Day of Radiology (IDoR). This year’s theme is dedicated to emergency radiology, and the essential role that radiologists play in the emergency room.
The International Day of Radiology is celebrated on November 8, because it is the anniversary of the 1895 discovery of the X-ray by German physicist Wilhelm Röntgen.
Radiologists are not always the most visible members of the healthcare team, but, in many cases, they are the ones who provide the answers about a patients’ condition. Our radiologists use images produced with a variety of techniques and technologies, to pinpoint the exact nature and location of your fracture, whether your head has sustained any serious damage, and whether your stomach pains are due to a swollen appendix.
The International Day of Radiology serves an excellent opportunity to build greater awareness of the value that radiology research, diagnosis and treatment contribute to safe patient care, and better understanding of the vital role radiologists perform in healthcare delivery.
Radiologists in the emergency room increase the quality of care and treatment of patients.
October is Breast Cancer Awareness Month! This annual campaign was created to increase awareness of the disease. Most people are aware of breast cancer, but often forget to take the actions necessary to detect the disease in its early stages and encourage others to do the same.
Make your Mammogram a Priority
At Peninsula Radiology, we want to encourage women to get their yearly mammograms, and invite others to do the same. Breast Cancer is the most common cancer, and the second leading cause of cancer-related deaths in women in America. Before the onset of mammography screening, the death rate from advanced breast cancer remained unchanged for 50 years. Since 1990, this rate has decreased by 30 percent, and recent studies suggest that mammograms may be more effective than previously thought, reducing breast cancer mortality by more than 30 to 60 percent.
It is important for physicians to educate their patients on the benefits of mammography, and to provide them with the proper resources, so that they may make the best decisions for their well-being. Early detection is key and keeping an annual appointment for a mammogram can save lives.
How do I get a Mammogram?
We make it easy and convenient for you to schedule your annual Mammogram. Thanks to Riverside’s Self-Scheduler, you can now schedule your screening mammogram from any computer, at any time. The Self-Scheduler is simple and quick to use. You will first need to create an account by selecting a username and password. Once your account is setup, you will be able to schedule, re-schedule or cancel your appointment at your convenience.
Dr. David Schengber says, “The more squeeze you can tolerate, the better we can detect disease. There is a lot of emotion, stress and anxiety associated with mammograms and breast cancer. But make getting a mammogram a habit, something you do every year. Just like getting your teeth checked.” -David Schengber, MD, the lead radiologist at Riverside Walter Reed Hospital.
September 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:
- 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
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 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.

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.
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:
CNS (central nervous system) problems
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.
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:
vascular diseases and aneurysms (both pulmonary and aortic)
skeletal problems (showing even very small bones and surrounding tissue and muscles)
A CT scan is also a helpful tool for:
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.

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 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.
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.
