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

Figure 7

Linear regression and Bland-Altman analysis of RV quantification using 2D and 3D cine MRI. (a)–(c): RVEDV and RVESV, RVSV, and RVEF measurements from seven volunteers with 3D self-gated free-breathing technique (-axis) versus standard 2D breath-hold technique (-axis), identical lines plotted as solid lines. (d)–(f): Bland-Altman plots of RVEDV and RVESV, RVSV, and RVEF measurements. The central dashed lines show the mean bias and the upper and lower dotted lines show the variation limits (±2 SD).
