Definition

A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze the function of your internal organs.

A SPECT scan is a type of nuclear imaging test, which means it uses a radioactive substance and a special camera to create pictures of your organs. While imaging tests such as X-rays can show what the structures inside your body look like, a SPECT scan produces three-dimensional images that show how your organs work. For instance, a SPECT scan can show blood flows to your heart or what areas of your brain are more active or less active.
