Karin Markenroth Bloch, Marcus Carlsson, Håkan Arheden, Freddy Ståhlberg
2009 BMC Medical Imaging  
Global LV perfusion was calculated by dividing CS flow with left ventricular (LV) mass.  ...  However, the ability of newly developed faster MR sequences to measure coronary flow during a breath-hold at 3T has not been evaluated.  ...  Conclusion The proposed method for quantifying CS flow and global LV perfusion at 3T with segmented PC MR, accelerated by SENSE, holds promise for clinical use.  ...
