PET stands for Positron Emission Tomography. A PET/CT scanner is an integrated device containing both a CT scanner and a PET scanner with a single patient table. PET images are created after intravenous injection of a tiny amount radioactive glucose called FDG. Glucose is taken up by all cells in the body, but is taken up to a greater degree by tissue with high metabolic activity such as cancer. FDG PET is also useful in the evaluation of certain neurologic conditions in the brain by identifying specific areas of decreased metabolism, and in the heart by evaluating the viability of heart muscle tissue.
CT is a tomographic imaging technique that uses an x-ray beam to produce detailed anatomic images. The anatomic information provided by CT is combined with the metabolic information provided by FDG PET into a single imaging examination. The PET/CT exam is interpreted by a highly skilled radiologist with training and expertise using state-of-the-art computer technologies. For more information click here.
