Role of cardiac CTA in estimating left ventricular volumes and ejection fraction

Figure 4 Shows some compromise in the time volume data as shown by the lack of smooth transition of the volume curve, and this likely represents some registration artifact towards the later part of diastole due to arrhythmias such as atrial fibrillation or frequent PVCs. This can lead to errors in the calculation of Left ventricular ejection fraction (LVEF). A quick look at the analysis of this time volume curve data is helpful to assess the quality of the data obtained for LVEF assessment and its limitations.
