What is SPECT and How Does It Work?

SPECT stands for Single Photon Emission Computerized Tomography Scan. This 3D scan allows doctors to assess the function of specific organs or tissues, as well as help diagnose bone issues like fractures. 

Patients receive a safe, radioactive tracer by an injection in the blood, inhalation or swallowing. A special camera is used to record where the tracer goes in the body. A SPECT scan is commonly used to help diagnose or monitor problems with the heart, bone and brain disorders, including blood flow, identifying blocked vessels, heart pumping efficiency, and identifying seizure activity in the brain.
