Gated SPECT uses electrocardiographic signals to acquire serial ventricular myocardium perfusion image sets that correspond to different phases of the cardiac cycle. Those image sets can be played back in a cine mode to allow assessment of segmental and global left ventricular wall motion (3, 4). Information readily available on cinematic display but rarely examined is the right ventricular size and wall motion.We encountered two patients with unexplained right ventricular dilatation and hypokinesis detected by gated ...References1.
