Emission computed tomography

Emission computed tomography (ECT) is a type of tomography involving radioactive emissions.

Types include positron emission tomography (PET) and Single-photon emission computed tomography (SPECT).

The imaging agent used in SPECT emits gamma rays, as opposed to the positron emitters (such as F) used in PET. There are a range of radiotracers (such as Tc, In, I, Tl) that can be used, depending on the specific application.
