Respiratory motion customarily degrades the resolution of a routine hepatic scintigram. Four analog motion-correction methods were analyzed and their abilities to maintain good spatial resolution over a broad range of liver scintigraphy parameters were measured. The analog circuit described can maintain the spatial resolution of the scintillation camera within 2 mm of the full width at half maximum of the stationary point-spread function. Clinicians require about 50% greater film density contrast to detect a 2 cm diameter lesion if motion correction is not used. In 14% of the cases studied, the addition of a motion-corrected anterior view to the usual 4 view liver study (performed without motion correction) resulted in a changed clinical interpretation. Analog motion correction should be provided in all scintillation cameras used for liver scintigraphy.
