PET/CT Scans

Advanced technology for improved cancer diagnosis and treatment

PET Scanner

Now, southwestern Illinois communities have access to another level of advanced technology with a powerful new diagnostic imaging system (PET/CT) that will continue to elevate St. Elizabeth’s Cancer Care Program as well as other health care services at the hospital!

HSHS St. Elizabeth’s Hospital’s new PET/CT service utilizes the Discovery STE unit, the most advanced 2-in-1 medical imaging technology from Shared Medical Services. It encompasses 3-Dimensional technology with a 16-slice scan for high-definition images.

What to know about PET/CT

PET/CT (Positron Emission Tomography/Computed Tomography Imaging) combines the functional information from a Positron Emission Tomography (PET) exam with anatomical information from a Computed Tomography (CT) exam in one single exam.

A PET scan detects changes in cellular function- specifically, how your cells are utilizing nutrients like sugar and oxygen. Since these functional changes take place before physical changes occur, PET can provide information that enables your physician to make an early diagnosis.

The advantage of CT is its ability to take cross sectional images of your body. These are combined with the information from the PET scan to provide more anatomic details of the metabolic changes in your body.

The PET exam pinpoints metabolic activity in cells and the CT exam provides an anatomical reference. When these two scans are fused together, your physician can view metabolic changes in the proper anatomical context of your body.

A PET/CT can be used to more accurately diagnose and locate cancers with increased patient comfort and a reduced number of scanning sessions. In addition, this hybrid technology offers better imaging data.
