SPECT / Gamma Camera Scan

Service Overview

Single-photon emission computerized tomography (SPECT) scan is used to analyze the functions of the 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 3D pictures.

While imaging tests such as X-rays can show what the structures inside your body look like, a SPECT scan produces images that show how your organs work. For instance, a SPECT scan can show how blood flows to your heart or what areas of your brain are more active or less active.

A SPECT scan integrates two technologies, i.e computed tomography (CT) and a radioactive material (tracer) to view the body. Doctors can see how blood is pumped to tissues and organs because of the tracer.

A radioactive substance is given through IV and the tracer dose is very small but the radioactive substance is absorbed more by the most active tissues. The SPECT machine camera detects the absorbed radioactive tracers in the body, it takes pictures and they are sent to a computer that creates a 3D image of the body or body part.
