The Center for Medical Imaging offers a full range of PET/CT studies utilizing the most advanced imaging technology available in our community. As the name implies, PET/CT is a marriage of two separate technologies: PET (Positron Emission Tomography), which uses an injected tracer to measure metabolism of both diseased and healthy tissue, and CT (Computed Tomography), which provides excellent visualization of anatomy. By bringing these two imaging modalities together in a single scan, PET/CT doctors are able to view highly defined 3D images from inside the human body. This advanced technology enables doctors to exactly identify the sites and extent of disease with never-before-seen accuracy.

One of the most important factors in the fight against disease is early diagnosis. PET/CT can detect changes in cell function or disease long before they are evident as physical or anatomical changes seen on CT or MRI. PET is particularly useful in the evaluation of alzheimer and dementia, solitary lung nodule, lung cancer, colon cancer, melanoma, lymphoma, head and neck cancer, and staging of breast cancer.

Cancer and other diseases can be detected at an earlier stage, potentially allowing definitive treatment to begin before the disease has a chance to spread. PET/CT has also been used to more accurately target radiation treatment and surgery to areas of disease while sparing healthy tissue. A patient’s prognosis improves with PET/CT’s ability to pinpoint the exact location of disease and in many cases, avoid unnecessary surgery and procedures.

Preparing for your scan
In order for your PET/CT scan to be successful, please adhere to the following pre-examination instructions.

• No physical activity 24 hours prior to your exam.
• Low carb, high protein dinner the night before your exam.
• Drink plenty of water the day of your exam.
• No food or drink (other than water) 4-6 hours prior to your study is recommended.
• Continue to take any prescribed medications unless instructed otherwise (insulin can be taken 2 hours prior to exam.)
• If pain or anxiety medications are necessary, please make arrangements for a driver.
• Notify your physician if you are pregnant, breast-feeding or diabetic.
• Wear warm, comfortable clothing please do not wear jewelry.
• Please expect to spend approximately 2 ½ hours at our Center.

During your scan – what to expect
On the day of your scan, after registering, you will go to a preparation area where you will receive a small injection of a harmless, low-dose radiolabeled glucose called F-18 FDG.

This tracer material will circulate through your body and will be metabolized, or “used”, by the cells and organs. Some cells and many diseases use this glucose more than others, and the PET system can actually measure these differences.

For this reason, you will be asked to rest for approximately 90 minutes while the glucose is distributed throughout the body.

You will then be asked to lie very still on the scanner bed for the duration of the scan. The Center for Medical Imaging’s PET/CT scanner was designed with patient comfort in mind. Our equipment is designed so that light and air flow freely throughout for your comfort. It is important that you remain as still as possible for the scanner to capture the best possible images. Simply relax and follow the technologists instructions, they will keep you informed throughout the exam through an intercom system. Your scan will take approximately 30 to 45 minutes.

After your scan – what to expect Your activity will not be restricted. You may drive if you wish, resume your normal diet, exercise and take all prescribed medications.

The Center for Medical Imaging’s radiologist will review your PET/CT scan and send a diagnostic report to your doctor. Your doctor will review this information in context of your care, and talk with you regarding the results.
