PET-CT Scan

Detection at the Molecular Level

What is PET-CT?

A positron emission tomography (PET) scan is an imaging test that allows doctors to check for disease in your body. Tracers are injected into the vein and are then highlighted under a PET scanner. These tracers allow doctors to see how well your organs and tissues are working. The PET scan is able to measure things like blood flow, oxygen use, and how your body uses sugar.

How Can I Prepare?

Dress in comfortable, warm clothing (as some scanner rooms may be cool). Avoid wearing jewelry or clothes with metal fasteners and zippers. Generally, the day before the exam patients are asked to eat a high protein diet, limit sugar intake, and avoid caffeine by only drinking water. On the day of the exam, patients are asked to only intake water and avoid eating. Specific instructions will be given when making your appointment.

What Can I Expect?

Upon arrival, our medical team will explain your procedure and answer any questions. An IV will be placed and you will be asked to wait approximately one to two hours before the scan begins. The scan takes approximately 30 minutes, during which you will lie flat on your back, without moving. A dual imaging scanner will take images of your body to detect and record the distribution of the water-based substance in your body.

Understanding PET-CT Scans

A PET scan is typically an outpatient procedure, meaning that you will be able to go about your day after the test is complete. PET/CT is the combination of PET (positron emission tomography) and CT (computed tomography) imaging techniques within a single machine. The individual scans, which are performed in one session, can be presented separately or as a single, overlapping image. These two images present different types of information about the human body. While PET shows metabolic or chemical activity in the body, CT shows the anatomical structure of the body.

The Only One in the Region

We provide the only fixed PET/CT services in the region. Oncology can assess tumor aggressiveness and monitor therapy success. It also can detect recurrent tumors and provide whole-body survey, as well as identify benign and malignant growths and help plan radiation therapy. The machine can help us brain diagnose Alzheimer’s and other dementias including movement disorders–like Parkinson’s disease–determine the location of epileptic seizures, and evaluate tumor recurrence.
