Cardiovascular MR (CMR) is used to acquire function, morphology, and composition of the heart which aids in clinical diagnosis and management. While measures such as ejection fraction, ventricular dimensions, and presence/pattern of late gadolinium enhancement (LGE) have stood the test of time as diagnostic pillars, newer quantitative tissue property measurements such as T1, T2, and extracellular volume (ECV) can characterize diffuse fibrosis, inflammation, or infiltration. The purpose of this study was to integrate multiple quantitative measurements into a single 20-min free-breathing, non-ECG, motion-resolved whole ventricular 3D acquisition using CMR Multitasking, including cardiac function, pre-contrast T1/T2, ECV, and LGE images.
