PET CT

PET/CT scan of the abdomen

The BIOGRAPH PET/CT is a Diagnostic Radiology system that combines PET and CT into one unit.

PET (Positron Emission Tomography) utilizes a low-level radiopharmaceutical to visualize processes or functions within the body. CT stands for Computed Tomography or CAT Scan. This technique uses x-rays to make cross-sectional images (called slices) of your body. The structure of body organs is more clearly visualized than with conventional x-rays. Advanced system software in the BIOGRAPH PET/CT combines the anatomical information obtained from CT with the functional PET information to form not a photograph, but a biograph – an image that records living tissues and life processes with great precision and detail.

This test can be used to help detect and treat cancer, determine the effects of a heart attack, or aid in evaluation of brain abnormalities and nervous system disorders.

PET/CT Scans Offered at Our Facilities:

  • Cardiac PET
  • Brain PET

What to Expect

How is this test done?

You will be injected with a small amount of radioactive material, which is then absorbed by the particular organ that is being assessed. You will lay on a table that slides into the PET/CT scanner.

Is this test painful?

No, this test is relatively painless. However, some patients find that laying still for an extended period of time may be uncomfortable.

How to Prepare

Drink plenty of fluids in the 24 hours before your exam. Also, do not eat anything for four hours before your exam.

Avoid strenuous activity 24 hours in advance of your study.

Medications may be taken with a small amount of water.

If your exam includes oral contrast, you must drink them 2 hours before your exam. When you arrive for the exam you will be given another cup to drink. Please call our offices if you have a history of contrast reactions/allergies.

Equipment Used for This Procedure


Siemens Biograph TruePoint PET/64 CT

PET scans measure metabolic processes by sending gamma rays into the body that detect a radiopharmaceutical (or tracer) that was introduced into the body. With the aid of a CT x-ray scan, this provides a 3D image. The High Definition of the Siemens Biograph TruePoint PET/64 CT requires a lower dose than a typical scan, as well as decreased scan time.  This machine has 64 slice technology, whereas most facilities only have 16-slice technology. This means the slices of the image are thinner and therefore more precise than a typical scan because the area of concern is better localized. This helps your doctor make more a more accurate diagnosis.
