PET/CT (Positron Emission Tomography) scan combines PET and spiral CT technologies in one single exam. The PET exam pinpoints cell activity, and the CT exam provides the exact anatomic location within the body. When these two scans are fused together, the radiologist can in most cases determine in just one imaging session whether a mass is malignant or benign, whether treatment is working and where, or if, tumors are located within the body. Because this technology can detect tumors as small as 5 millimeters, nearly three times smaller than masses seen on traditional scans, it is one of the most sophisticated radiological tools available.
PET/CT is beneficial in the evaluation of the following disease/tumor sites:
- Head and Neck
