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.
