Caption: Heart attack. Coloured axial SPECT (single photon emission computed tomography) scan through a heart after a myocardial infarction (heart attack). The uptake of blood by the myocardium, the muscular wall of the heart, is shown in red. Part of the myocardium (upper centre) is not receiving blood. A reduced blood supply to one wall (left) of the heart, is also seen. The blood was labelled by the radioactive tracer technetium-99m (Tc-99m), which emits gamma ray photons and allows this computed tomography image to be constructed. For a SPECT scan of a healthy heart, see image P216/366.
