What Is a PET Scan?

PET ScanPeninsula Radiology offers multiple diagnostic tests that are intended to diagnose diseases that are hidden from the naked eye.  While many people know the names of the different types of tests and scans, most do not know what the scans are intended to do.  One of the types of tests that is commonly performed at Peninsula Radiological Associates is a PET scan.

What is a PET scan?

A positron emission tomography, more commonly known as PET, is a type of procedure used to scan for possible diseases inside of your body. It uses gamma rays given off by a tracer to make a 3D image of the interior of your body possible. The way this works is that you are given the tracer, which is swallowed or injected, and it gives off low levels of radiation that the machine can pick up on, allowing it to map the inside of your body. It is a painless procedure, and has few risks associated with it. At the longest, the radiotracer will be out of your system within a day.

Why get a PET scan?

It’s an easy procedure that can detect and measure numerous things about the body, with the most important and often the most relevant being your oxygen use and blood flow. The scan is simple and non-invasive.

Why a PET scan over something else?

A lot of very dangerous diseases can be detected earlier with the aid of a PET scan, from cancer to brain disorders. The test can give you early warning for life-threatening diseases.  It can also detect the stages of heart disease, and can prevent stroke and heart attacks if the disease is found early.

In short, a PET scan is a relatively easy test to perform that can help to diagnose life threatening health situations. If your doctor recommends it, then it is a procedure that could very well save your life.

If you have been advised or referred for a PET scan, contact our office for an appointment with one of our radiology professionals.  Our team of providers has the experience and skill to provide outstanding health services in a compassionate, caring environment.

 

What Is a Catheter Embolization?

iStock_000006042109Large-revAt Peninsula Radiology Associates, we believe patient education is an important facet of our services. We know that many of our patients like to familiarize themselves with procedures before we meet them. One of the procedures frequently performed is called catheter embolization.

What Is a Catheter Embolization?

Embolization, also known as catheter embolization, is a radiologic procedure used to introduce medications or synthetic embolic agents into a blood vessel to occlude — or block — blood flow. This procedure is often indicated to:

  • Stop abnormal bleeding, particularly gastrointestinal or pelvic bleeding.
  • Eliminate abnormal connections between arteries and veins, including AVMs (arteriovenous malformations) and AVFs (arteriovenous fistulas).
  • Cut blood supply to a tumor, including benign (non-cancerous) uterine fibroids in women and cancerous tumors in both men and women. Following embolization, a malignant tumor may shrink or grow more slowly, making chemotherapy and/or surgery more effective patient options.
  • Treat aneurysms, which are bulges or sacs formed in weak artery walls.
  • Treat varicoceles — enlarged veins — in the scrotum, which may contribute to infertility.

Embolization is a highly effective procedure, which can be performed on an outpatient basis. It helps you avoid more invasive surgical treatments or interventions for these and other common conditions when used alone. Catheter embolization may also be combined with other treatments such as surgery or radiation.

What To Expect During the Catheter Embolization Procedure?

During catheter embolization, a physician called an interventional radiologist will use fluoroscopy — an imaging process that is similar to X-rays, but provides live, real-time moving images of your body — to carefully guide a catheter to the area within your body requiring treatment. A catheter is a long, thin plastic tube measuring about one-eighth of an inch in diameter that can be threaded safely through your arterial system.

Once your catheter has been placed, your physician injects a contrast material with iodine through it so that X-rays can be taken to indicate the precise site of your bleeding or abnormality. Then your interventional radiologist inserts the appropriate embolic agent through the catheter. The precise agent placed depends on the condition for which you are being treated. Common embolic agents include:

  • Acrylic polymer spheres, which are used to permanently block small blood vessels.
  • Small metallic coils, which are frequently used to permanently stop abnormal bleeding.
  • Liquid sclerosing agents, which are chemicals designed to cause scarring in a blood vessel that permanently seals the vessel.

Post Procedure Recommendations

You are normally sedated, using either a moderate or general anesthetic, and fitted with an IV (intravenous) drip and monitors for your vital signs at the start of the procedure.

Since arteries have no sensation, you should not experience any discomfort from the catheter once it has been inserted. You may experience a warm feeling from the contrast dye or other sensations when your embolic agent is administered, depending on your level of sedation. X-rays are taken to verify the success of the procedure.

Bed rest is recommended for at least six to eight hours following your procedure. You may experience some side effects after catheter embolization. Pain is a common one and is controlled by either oral medication or medication administered through your IV.

The Musculoskeletal System Explained

musculoskeletalThe musculoskeletal system is the network of muscles and bones within the body. Injuries, conditions like arthritis, and other growth and degeneration problems can cause pain and disorders that cannot always be identified with a physical exam. It is a musculoskeletal radiologist’s job to conduct medical imaging of the problem areas to figure out what is happening to your body.

Musculoskeletal problems can be the result of anything from work accidents and sports injuries to genetics and lifestyle choices, and many other circumstances. Some of these problems include osteoarthritis of the knee, osteoporosis of the bones, and other joint or muscle issues.

In order to accurately diagnose and treat Musculoskeletal Conditions, Peninsula Radiology offers a full spectrum of imaging services. Our radiologist utilize CTMRI, musculoskeletal ultrasound, bone biopsies and bone mineral density studies to effectively look inside of a patient’s body. Since musculoskeletal disorders and injuries affect bones and muscles specifically, this is where these kinds of radiologists focus their attention. Thanks to these technologies and our expert staff, we are able to diagnose a wide range of disorders of the musculoskeletal system.

Our Musculoskeletal Imaging Radiologists work closely with our other departments to ensure that every diagnosis is accurate and that treatment plans for musculoskeletal conditions are the most effective available.

Conditions that fall in the range of Musculoskeletal Imaging include patients with the following:

  • Patients with disorders of the spine, upper & lower extremities
  • Arthritis
  • Cancers of the soft tissues & bones

For more than 50 years, Peninsula Radiological Associates has provided quality medical imaging services. Our team of board certified and fellowship-trained radiologists have over 200 years of combined experience.  As a team we deliver the most comprehensive range of medical diagnostic imaging and interventional radiological procedures available on the Virginia Peninsula.

Understanding Radiology

Screen Shot 2014-04-09 at 2.04.32 PMWhat is Radiology?

The field of radiology began with the discovery of X-radiation by Wilhelm Roentgen in 1895. Since then, radiology has evolved tremendously. These days, radiology is central to the clinical practice of medicine across a wide range of disciplines. It is the best practical way to diagnose, monitor treatment and detect progression or relapse of many important and common diseases in a minimally invasive manner.

What is the role of a Radiologist? 

Radiologists specialize in producing pictures of the human body using state-of-the-art imaging technology, such as X-rays, ultrasound, and magnetic resonance imaging (MRI). These medical specialists are central members of the multidisciplinary clinical care team who play a vital role in the diagnosis and treatment of diseases and injuries within adults and children, including babies and unborn fetuses.

What is Embolization and is it the Right Choice for You?

embolizationEmbolization is a way of therapeutically cutting off a supply of blood to a particular part of the body. This procedure can be used to prevent internal bleeding, stop the flow of blood to a tumor, treatment of aneurysms or to resolve abnormal connections between veins and arteries. Embolization is a less invasive way to address blood flow concerns than open surgery.

The benefits of embolization include:

  • Less Complications – Given that this is a less invasive procedure than open surgery the risk factors are reduced for patients.
  • No Surgical Incision – This procedure only requires a nick in the skin to insert the catheter and therefore no stitches are required.
  • Brief Hospital Stay – Most people need to stay in the hospital only the night after the procedure. Normal activities can usually begin in approximately one week.
  • Options When Surgery is Not Recommended – This method can be used to treat tumors and other vascular issues that can’t be removed surgically or would pose too great of a risk if surgery was attempted.

The procedure is done with the aid of x-ray imaging and a contract material so the blood vessel can be seen clearly. The doctor inserts a catheter into the blood vessel and moves it up to the area that needs to be treated. The catheter is a long, thin plastic tube that fits inside the vein or artery, it is approximately 1/8 inch in diameter so you can compare it to being smaller than a pencil lead used in a mechanical pencil. Once the catheter is positioned properly an embolic agent is inserted through the catheter and this synthetic material or medication is placed for the treatment.

Different types of embolic agents can be used depending on the size of the blood vessel and whether the agent need to be a permanent or temporary solution.
Embolization can provide treatment for a variety of medical needs, so discuss your particular situation with the doctor and they can answer your questions about the benefits and risks of their recommended course of treatment.

Embolization can be performed by the providers of Peninsula Radiology Associates. If your doctor has recommended embolization as the appropriate procedure for you, and you would like more information, please contact us at (757) 989-8830. We would be happy to help you decide if it’s right for you!

Ultrasound Facts For Your Consideration

ultrasound factsMany people associate an ultrasound scan with pregnancy, but an ultrasound can be used for many different medical purposes. In this post you will learn what an ultrasound is, what it is used for, and also the advantages and disadvantages of ultrasound scans.

What is an ultrasound scan?
An ultrasound scan, also known as sonography, uses sound waves to capture images of what is inside a person’s body. Much like a bat uses sounds and their echoes to “see” its surroundings, an ultrasound emits sound too high for a human to hear, and then records the echoes to determine the shape of organs or soft tissues. An ultrasound scan allows doctors to see what is inside the body without making an incision.

What do doctors use ultrasounds for?
Pregnancy. Many expectant mothers have an ultrasound performed so the doctor can see how the unborn baby is doing. Some health problems can be detected this way. Also, the parents get a first peek at the child, sometimes learning the sex of the baby.

Diagnosing health problems in many internal organs, such as:
-gallbladder
-kidneys
-liver
-ovaries
-uterus
-pancreas
-spleen
-thyroid
-testicles
-bladder
-eyes
-heart
-blood vessels

Medical Procedures:  Doctors may use an ultrasound scan during certain procedures, such as needle biopsies, to help in precision.

What are the advantages of using ultrasound imagery?
The biggest advantage: an ultrasound is virtually painless, and it does not require an incision.
Ultrasounds are safe! They do not emit any radiation, unlike X-rays and CT scans.
Also, ultrasounds detect soft tissues that X-rays do not capture well.
Ultrasounds are less expensive than many other imaging techniques.

Are there any disadvantages?
Certain areas of the body cannot be imaged using ultrasound. For instance, ultrasound scans cannot go through bone. They also cannot be used in organs where gas is present, such as the lungs.
Ultrasounds are not as detailed as other imaging techniques, and this lack of detail can sometimes result in misleading images.

In conclusion, ultrasound scans allow doctors to see organs and soft tissues without being invasive. This is useful for pregnancies and many other medical conditions. Medical technology continues to advance, giving doctors more and more options to diagnose and treat their valued patients safely and effectively.  If you have been told you are in need of an ultrasound, contact us at Peninsula Radiology at (757) 989-8830 to schedule an appointment.
