Using Cardiac MRI to Predict Outcomes in Patients With STEMI

Cine CMR imaging was performed with steady-state free precession covering short axis continuously from the mitral annulus to the apical level in the 2-, 3- and 4- chamber views using the following parameters: repetition time (TR) = 3.73 ms, echo time (TE) = 1.87 ms, flip angle = 60°, slice thickness 8.0 mm. Cine images of all included patients were acquired prior to contrast administrations. Late gadolinium enhancement images (LGE) images were obtained 10-15 minutes after intravenous injection of gadolinium (0.1 mmol/kg at 3ml/s) at end-diastolic phase on the short axis (TR=6.09 ms; TE= 3.0 ms; flip angle 60°; thickness 8.0 mm) with breath-hold phase-sensitive segmented inversion recovery (PSIR) fast field echo sequence. T2-weighted sequence was performed using turbo spin-echo (TSE)-sequence (TR=1714-2000 ms; TE=8.04 ms; slice thickness 8.0 mm) to estimate myocardial edema. Images were analyzed on freely available validated cardiovascular image analysis software CVI42 (Circle Cardiovas
