3D, 3-dimensional; BMI, body mass index, calculated as weight in kg/height in m²; DVR, diastolic volume recovery; Ecc, peak systolic strain rate; ECV, extracellular volume fraction; EDV, end-diastolic volume; EF, ejection fraction; ESV, end-systolic volume; PFR, peak filling rate; TPFR, time to PFR.

^*P value, for linear or logistic regression analysis as appropriate, relating ECV as the dependent variable and the column 1 value as the independent variable.

^†Results from a logistic regression analysis.
