Comparison of short-axis dark blood radial bSSFP (4-shots, 140 views) with dark blood Cartesian fast spin-echo. Top row: Breath-hold scans. The ventricular myocardium is well shown with radial bSSFP (left), whereas with Cartesian fast spin-echo (readout bandwidth 305 Hz/pixel) (right) there are motion artifacts that obscure the inferior wall (arrows) of the left ventricle and free wall of the right ventricle (arrowheads). Bottom row: Free-breathing scans in a different subject. Radial bSSFP (left) shows good image quality with only mild blurring, whereas Cartesian fast spin-echo (readout bandwidth 977 Hz/pixel) (right) is non-diagnostic due to severe ghost artifacts and myocardial signal dropout
