Purpose We test the reproducibility of human cardiac phosphorus MRS (31P‐MRS) at ultra‐high field strength (7 T) for the first time. The primary motivation of this work was to assess the reproducibility of a ‘rapid’ 6½ min 31P three‐dimensional chemical shift imaging (3D‐CSI) sequence, which if suff...
