Evaluation of myocardial microcirculation using intravoxel incoherent motion imaging.

Purpose: To explore whether cardiac magnetic resonance-intravoxel incoherent motion imaging (MR-IVIM) is feasible for the clinical evaluation of myocardial microcirculation.

Materials And Methods: The study included 30 patients (with hypertrophic cardiomyopathy, diabetes mellitus, hypertension, or combined diabetes and hypertension) and 34 healthy volunteers. MR-IVIM with a maximum gradient strength of 50 mT/m was performed on the left ventricular short axis (apex, middle, and base), using multiple b values (0-500 s/mm ) on a 3.
