Cine imaging (top panel), ³¹P-CMRS (middle panel) and ¹H-CMRS (bottom panel) showing representative results of LVM/EDV, PCr/ATP and Lipid/water for heart failure with preserved ejection fraction (HFpEF) (left) and control (right). ¹H-CMRS spectra are scaled based on unsuppressed water (not shown) and noise level. LVM = left ventricular mass; EDV = end-diastolic volume; CMRS = cardiovascular magnetic resonance spectroscopy
