CMR images were obtained with the same study protocol in both participating hospitals (Kuopio and Helsinki University Hospitals) as described previously14. Delayed-enhancement images were obtained 10 minutes after injection of gadoterate meglumine (Dotarem®) 0.2 mmol/kg contrast agent using segmented trueFISP IR sequence in short axis orientation and in two long axis orientations (4- and 2-chamber views). The imaging parameters were 700 msec temporal resolution, 1.08 msec echo time, flip angle 50°, acquisition matrix 192 × 144 and 340 × 340 field of view. Slice thickness was 8 mm and intersection gap 20%. Inversion time was optimized to null the signal intensity of normal myocardium.
