Myocardial perfusion imaging is an invaluable tool to diagnose and study coronary artery disease. Complete coverage of the heart without sacrificing temporal or spatial resolution is desired. Many approaches aim to achieve the desired goal by undersampling k-space data for each time frame and using sophisticated reconstruction algorithms like compressed sensing. Another complementary approach to increase coverage without compromising spatio-temporal resolution is simultaneous multi-slice imaging in which multiple slices are simultaneously excited with phase modulation and acquired simultaneously. Here we combine CAIPI, a simultaneous multi-slice method, with compressed sensing for radial myocardial perfusion and present promising results.
