Emission computed tomography (ECT) is a type of imaging technique used in medical diagnostics to visualize the distribution of radioactive materials in the body. It works by detecting the gamma rays emitted from a radiotracer that has been administered to the patient. There are two main types of ECT: Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT).
