Non-ECG gated contrast-enhanced computed tomography in axial-plane; on a four-chamber view of the heart, showing perfusion defect in the intra-ventricular septum and apical segments (black arrows). On quantitative analysis, the Hounsfield Unit (HU) for region of interest (ROI) in the perfusion defect was 40.8 HU (±6.9 HU) compared to remote myocardium 94.5 HU (±7.3 HU).
