An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell
metabolism
. It has been useful in study of soft

such as CANCER;
CARDIOVASCULAR SYSTEM
; and
BRAIN
. SPECT is closely related to PET, but uses
isotopes
with longer half-lives and resolution is lower.
