MRI approach for depiction of changes in global myocardial tissue characteristics. Midventricular short-axis T2-weighted short inversion-time inversion-recovery (STIR) fast spin-echo (left), T1-weighted fast spin-echo before (middle) and at 4Â min after administration of 0.2Â mmol of gadolinium DTPA/kg body weight (right). Calculation of the ratio of the differences in signal intensity between myocardial and skeletal muscle using T2-weighted STIR fast spin-echo allow generalised myocardial oedema to be depicted (left), while the changes in signal intensity early after contrast medium administration allow myocardial hyperaemia to be visualised (right)
