The accuracy of conventional CT images of the beating heart is severely diminished by motion artifacts: only marked abnormalities are routinely demonstrated. Recent CT advances have allowed for faster scanning via electron beam (EBCT) and double helical computerised tomography (DHCT). The latter effectively doubles the volume scanned within a given time but, while both techniques enable the entire heart to be scanned within a single breath-hold and with superior contrast enhancement and minimal respiratory artifact, EBCT is suitable for cardiac gating.
