Right ventricular myocardial infarction (RV-MI) is a serious consequence of coronary artery disease that adversely affects outcomes. Conventional CMR employs 2D breath-held imaging (CMRBH) to detect RV-MI, an approach that may sacrifice spatial resolution to enable patient breath-holds, and is thus suboptimal for imaging the RV. This study compared 3D navigator-gated free breathing CMR (CMRNAV) to CMRBH for detection of RV-MI in 75 post-MI patients. Results demonstrated a 2-fold increase in detection rate of RV-MI by CMRNAV, accompanied by higher spatial resolution in 30% less scan time.
