Free-Breathing 3D Imaging of Right Ventricular Structure and Function Using Respiratory and Cardiac Self-Gated Cine MRI

Figure 5

Comparisons of cine images acquired with the standard breath-hold 2D and the proposed free-breathing 3D techniques. Cardiac short-axis images of end-diastolic phase and end-systolic phase obtained with breath-hold 2D technique are shown in (a) and (b), and those obtained with the 3D technique are shown in (c) and (d), respectively. The asterisk denotes the RV.
