Traditional, forgotten and new left ventricular systolic function parameters on a 64-row multidetector cardiac computed tomography: A reproducibility study

Abstract

s). The derived parameters were calculated as the PER normalized for LVEDV (PER-V, 1/s), the PER normalized for LVM (PER-M, mL/g × s) and the PER normalized for LVEDV times the PER normalized for LVM product (PER-VM, ml/g × s 2 ). Considering the errors percentages, the respective values for intra-and inter-observer errors were around 5% and 8% for standard LV systolic measures. The percentage intra-observer errors For the independent reader the corresponding values were -15.2% and +15.5%, -12.3% and +16.3%, and -26.6% and +30.9%. The intra--class coeffi cients for repeated measurements for both the same reader (intra-observer) MDCT examinations. (Cardiol J 2013; 20, 4: 385-393)
