CT Scan (Computerized Tomography, CAT Scan) – an X-ray procedure that combines many X-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. A CT scan is used to define normal and abnormal structures in the body. It is also used to assist in procedures by helping to accurately guide the placement of instruments or treatments.

Positron Emission Tomography (PET) – a test that uses a special type of camera and a tracer (radioactive chemical) to look at organs in the body. During the test, the tracer liquid is put into a vein in your arm. The tracer moves through your body, where much of it collects in the specific organ or tissues. The tracer gives off tiny positively charged particles (positrons). The camera records the positrons and turns the recording into pictures on a computer. A PET scan may be used to look for cancer, check blood flow, or find out how well organs are working.
