3 Tesla MR cardiac applications: 6 months experience of daily clinical practice with emphasis on comparison with 1.5T Tesla for myocardial viability evaluation

Purpose: To compare 3Tesla cardiac imaging with 1.5 Tesla for myocardial viability evaluation in nearly identical experimental conditions. Methods: 35 patients (mean age 63±11; 94.2% male) underwent both 3T and 1.5 T MR cardiac examination. Comparison between two scanner was made on the basis of the same study protocol that includes: cine b-FFE 2 and 4 chamber views multiple short-axis views (every 1cm throughout the entire LV). Perfusion is evaluated after Gadolinium injection (0.15 mmol/kg). Delayed Enhancement evaluation is performed with a segmented inversion-recovery technique. Image quality was assessed me…
