Positron Emission Tomography (PET) 1. uses radioisotopes such as Carbon-11, Nitrogen-13 2. effects of drugs, site of molecules, cancer cells 3. very good at studying glucose absorption by neurons in the brain during certain tasks G. Digital Subtraction Angiography (DSA) 1. takes X-ray picture before and after administration of contrast substance to the vessels 2. used to study vessels of the brain and heart to help prevent strokes and heart attacks Computerized Axial Tomography (CAT) Scanning anatomy 1...
