WebIn SPECT, image quality is compromised by several factors including photon attenuation, photon scatter, the partial volume effect, and motion artefacts. These variables also confound the capacity of SPECT to quantify the concentration of radioactivity within given volumes of interest in absolute units, e.g. as kilobecquerels per cubic centimetre. A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze your body's organs, tissue and bones. A SPECTscan is a type of nuclear imaging test, which means it uses a radioactive substance and a special camera to create 3D pictures.
