Spatial vs temporal resolution in real-time radial FLASH CMR. T1-weighted images (spoiled FLASH, flip angle 8°) of a short-axis view during systole at 2.0 mm (TR/TE = 2.0/1.3 ms), 1.5 mm (TR/TE = 2.2/1.4 ms), and 1.0 mm resolution (TR/TE = 2.8/1.8 ms) using data sets with only 19, 15, and 11 spokes, respectively. Individual acquisition times are given by the # spokes × TR and range from 22 ms (upper right: 11 spokes and TR = 2.0 ms) to 52 ms (lower left: 19 spokes and TR = 2.8 ms). The images were selected from respective real-time CMR movies reconstructed by nonlinear inversion and zoomed by a factor of 1.5.
