Positron Emission Tomography (PET) is a sophisticated imaging technique that allows our radiologists to view organ function and tissue metabolism—how rapidly cells grow. A combined PET/CT exam merges a CT scan that provides detailed anatomy with a PET scan that shows organ and tissue function. PET/CT scans are valuable in identifying certain diseases, particularly cancers, often before they are visible on other imaging tests. PET/CT scans are used to diagnose and manage these diseases since they can pinpoint disease location and show how well diseases or tumors are responding to treatment such as chemotherapy or radiation. A PET/CT scan can also be used to study the brain for signs of Alzheimer’s disease.

Advanced Radiology offers Connecticut’s only permanent PET/CT scanner at an outpatient facility

Our radiologists review the images in real time during the scan for prompt answers for your doctor. Our PET/CT scanner can complete whole body surveys that permit better cancer detection and staging, which leads to more precise biopsy and treatment planning.

PET/CT scans are available at the following Advanced Radiology locations

A PET/CT scan will take about 2 hours and requires an IV injection of a small amount of a radioactive compound or “tracer” that resembles sugar. You will rest quietly for about one hour so the tracer can circulate through your body before the exam begins. The compounds, which are necessary for the production of images, lose their radioactivity—usually within hours or days—and are eliminated from your body. You can resume normal activities immediately after the test.

A PET/CT scan requires that you refrain from strenuous exercise for 24 hours prior to the exam. You should not drink or eat for 4-6 hours prior to the exam. If you must take oral medications, please take them with a minimal amount of water, or you may bring your medication to the office and take immediately following the study. If you have any questions, please feel free to ask us.

NOTE: Diabetic patients will require special preparation and should call the Advanced Radiology for instructions.
