DOIAbstract
Delayed-phase cardiac CT is a useful tool for scar detection, based on differences in the volume of distribution of iodine. Although it covers the entire heart, provides uniform, high isotropic spatial resolution, and therefore may be useful for detecting small late iodine enhancement (LIE), we need to correctly differentiate small LIE and pseudo-lesions mimicking LIE. In this case report, we demonstrate basal septal perforator vein mimicking LIE in delayed phase cardiac CT. Left ventricular myocardium includes not only septal vein and artery but also capillaries, arterio- and venoluminal vessels, and sinusoids, etc. which connect to septal veins. To avoid misinterpretations of myocardial LIE on the delayed phase images, we need to understa...
