SPECT scanning. A radiologist positions a woman under a dual-head SPECT (single photon emission computed tomography) scanner. SPECT scanning is a form of radionuclide scanning that allows cross-sectional images of the distribution of a radioactive tracer in particular organs to be obtained. The patient is first injected with the tracer, which concentrates in active parts of particular organs - such as the heart muscle in investigations of heart disease. The image is produced by a radioactivity-detecting gamma camera (in this case by two), which takes multiple shots from different angles.
