Physiologic stress CMR perfusion provides unique information regarding the patients exercise capacity, hemodynamic response to exercise, and the extent of physical activity that can reproduce the patients symptoms during imaging. Accelerated non-Cartesian imaging has shown promises as an alternative to Cartesian sampling for CMR perfusion after physical exercise due to a) its efficient k-space sampling, b) better motion properties, and c) lower dark-rim artifacts. In this study, we sought to compare the performance of four non linear reconstruction methods for accelerated CMR perfusion with radial sampling after exercise on an MR-compatible supine bike ergometer.
