From: Real-time cardiovascular magnetic resonance at high temporal resolution: radial FLASH with nonlinear inverse reconstruction

Figure 9

Real-time radial FLASH CMR at 2.0 mm spatial resolution and 22 ms temporal resolution. Consecutive T1-weighted images (spoiled FLASH, TR/TE = 2.0/1.3 ms, flip angle 8°, 11 spokes) of a 2-chamber view at 2.0 mm resolution, 8 mm section thickness, and 22 ms acquisition time. The images depict two 176 ms periods (8 images) of a single cardiac cycle that are 682 ms (31 images) apart: (a) opening of the mitral valve and resulting blood stream into the left ventricle, (b) turbulent flow leading to a vortex at the apex of the left ventricle. They were selected from a respective real-time CMR movie reconstructed by nonlinear inversion (see Additional File 2) and zoomed by a factor of 1.5.
