SPECT (Single Photon Emission Computed Tomography)

SPECT, or Single Photon Emission Computed Tomography, is a medical imaging technique that creates detailed 3D pictures of how organs like the brain or heart function. It involves injecting a small amount of a radioactive substance, called a tracer, into the patient. The tracer emits gamma rays that a special camera detects. A computer then processes these signals to generate images showing blood flow, activity, or other functions within the body. SPECT helps doctors diagnose and monitor conditions such as coronary artery disease, brain disorders, and more by providing functional information that complements traditional images.
