Changes in the myocardial energy homeostasis have been linked to decreases in cardiac pumping performance. Current MR practice requires two consecutive recordings of ³¹P-MRS and ¹H-MRI to assess both aspects of heart physiology, with consequently long scan times, considerable patient burden, and potentially a mismatch between data from separate sessions. By efficiently interleaving 3D ISIS acquisitions for localized ³¹P-MRS with short-axis cine ¹H-MR imaging, both myocardial energy status as well as left-ventricular ejection fraction could be quantified from MR data that were acquired essentially simultaneously.
