Studies were performed using a 1.5-T MRI scanner (Philips; Best, the Netherlands; or General Electric, Milwaukee, WI) with a cardiac-dedicated, phased-array coil. The CMR studies were ECG triggered by standard software and obtained in diastole to minimize artifact due to cardiac motion. Studies consisted of multislice-multiphase steady-state–free precession (SSFP) in 55 patients, spin echo in 54 patients, and fat-saturated, T2-weighted breath-hold sequences in 55 patients. Studies were obtained of the short-axis (SA), vertical long-axis (VLA) and 4CH views. SSFP sequences were performed to assess regional wall motion abnormalities, and T2-weighted studies were performed to assess the presence of myocardial inflammation. Ten minutes after the additional administration of 0.1 mmol/kg gadolinium diethylenetriamine penta-acetic acid (Schering; Berlin, Germany), SA and 4CH images were obtained with spin echo in 54 patients (slice thickness, 8 mm; gap, 0.8 mm; matrix, 512 × 512; field of view, 380 mm; voxel size, 0.7 × 0.7 × 8 mm) and three-dimensional breath hold inversion recovery-gradient echo (IR-GRE) sequences (SA, VLA, 4CH) in 15 patients (slice thickness, 10 mm; no gap; matrix, 256 × 256; field of view, 400 mm; voxel size, 1.6 × 1.6 × 10 mm) to assess for the presence of late gadolinium-enhancing (LGE) lesions. Fourteen patients underwent both spin echo and IR-GRE studies. The inversion time (250 to 400 ms) was determined on an individual basis to obtain optimal nulling of the unenhanced myocardial signal.
