Authors' Note: Absorption of rays by body tissues complicates the interpretation of medical imaging with nuclear techniques. ‘Hybrid' scanners combine the nuclear camera with a CT x-ray unit that provides maps of attenuation; this technique for correction of attenuation (known to workers in the field as A.C.), makes the nuclear scan more accurate in the detection of various lesions, in particular, abnormalities in blood flow to the heart muscle, and studies of deeply-located tumors, e.g. somatostatin scans.
The combination of the two scanners (nuclear and X-ray CT) has been given the puzzling name “SPECT-CT”.
