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/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

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 exam detects changes in cellular function – how your cells are utilizing nutrients like sugar and oxygen. Since these cellular-level changes often preceed more substantial problems, 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. One advantage of CT is its ability to rapidly acquire multiple two-dimensional image slices of your anatomy. Using a computer these 2-D images can be presented in 3-D for in-depth clinical evaluation.

The PET exam pinpoints increased 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 exam not only helps a physician diagnose a problem, it also helps predict the likely outcome of various therapeutic alternatives, pinpoint the best approach to treatment, and monitor progress.
