What are pet scans? What exactly is a pet scan?

Positron : Positron emission tomography (pet) is a test that uses a special type of camera and a tracer (radioactive chemical) to look at organs in the body. The tracer usually is a substance (such as glucose) that can be used (metabolized) by cells 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 tissue. The tracer gives off tiny positively charged particles (positrons). The camera records the positrons and turns the recording into pictures on a computer. Pet scan pictures do not show as much detail as computed tomography (ct) scans or magnetic resonance imaging (MRI) because the pictures show only the location of the tracer. The pet picture may be matched with those from a ct scan to get more detailed information about where the tracer is located. A pet scan is often used to evaluate cancer, check blood flow, or see how organs are working.
