All patients had a cardiac T2* MRI, with the imaging carried out using a 1.5 Tesla MRI scanner (Philips Achieva, the Netherlands) with a sense cardiac phase array of a five-element coil, or SENSE XL Torso 16-element coil, as was used in previous studies.[29 (link)] Cardiac T2* was measured from a single short-axis view at the mid-left ventricle with 10 echo times (1.70–26.10 ms with an increment of 2.70 ms). The cardiac T2* protocol included a double inversion recovery black blood gradient echo. A multiecho sequence was applied with a flip angle of 25°, matrix 164 × 154, field of view 36 cm, TR 28 ms, slice thickness 10 mm, and number of signal averages = 1. Data analysis was performed on the workstation with the validated in-house software developed on the MATLAB R2014b (Mathworks, Natick, MA, USA).
