PET/ CT Fusion
PET/CT combines the functional information from a positron emission tomography (PET) exam with the anatomical information from a computed tomography (CT) exam into one single exam.
What is it?
PET/CT combines the functional information from a positron emission tomography (PET) exam with the anatomical information from a computed tomography (CT) exam into one single exam. A PET scan detects changes in cellular function—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. A CT scan uses a combination of x-rays and computers to give the radiologist a non-invasive way to see inside your body.
Our Ashland location offers this exam on site.
What are the benefits ?
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. One advantage of CT is its ability to rapidly acquire two-dimensional pictures of your anatomy. Using a computer these 2-D images can be presented in 3-D for in-depth clinical evaluation. Your PET/CT exam results may have a major impact on your physician’s diagnosis of a potential health problem and, should a disease be detected, how a treatment plan is developed and managed.
A PET/CT exam not only helps your physician diagnose a problem, it also helps predict the likely outcome of various therapeutic alternatives, pinpoint the best approach to treatment, and monitor your progress. If you’re not responding as well as expected, you can be switched to a more effective therapy immediately.
