Panel A-D illustrate the effect of exposure time on measure volumetric values. Increasing the exposure time improves k-space sampling but results in temporal blurring. Panels E-H illustrate the effect of reconstructed frame rate on measure values. As the frame rate decreases, the local maxima and minima values are not obtained leading to changes in hemodynamic evaluation. The proposed method was utilized to image patients with frequent irregular arrhythmias. The improvement in image quality is shown for two different slice locations Panel I-L and N-Q. Standard EKG-gated images are shown at end-diastole (I and N) and end-systole (J and O). The real-time method shows improved image quality at both phases (end-diastole: K and P, end systole: L and Q). Furthermore, by obtaining volume for 8 seconds, the occurrence of premature beats can be observed (M and R). End-diastolic points are labeled blue and end-systolic points are labeled with a red dot.
