Non-contrast
pulmonary vein (PV) MR angiography (MRA) is an alternative to the clinical
contrast-enhanced technique. We have recently developed a non-contrast PV MRA
technique using a sagittal selective inversion pulse. However, the resulting
acquisition time is significantly longer than breath-hold contrast-enhanced
technique. In this study, we investigate the feasibility of using compressed
sensing for accelerating data acquisition in non-contrast PV MRA. We use a
distributed compressed sensing
technique to reconstruct separate coil images simultaneously. We show
that this reconstruction yields good results even at high rates (x10).
