Fifty patients with ischaemic heart disease have been studied by electrocardiographically gated computed tomography (CT) and left-ventricular angiography to assess the accuracy of the former in the measurement of left-ventricular volumes and ejection fraction. There was no significant difference in the measurements of end-diastolic volume (p = 0.9, r = 0.81). Computed tomography significantly overestimated end-systolic volume (p less than 0.001, r = 0.89) and significantly underestimated ejection fraction (p less than 0.001, r = 0.74). Although there is some variation between the two sets of measurements, the correlation between the two techniques is good, indicating that electrocardiographically gated CT could be a useful noninvasive technique for assessing left-ventricular function.
