Purpose: To implement myocardial first-pass perfusion imaging at 3 Tesla and to evaluate the potential benefit with regard to signal parameters in comparison to 1.5 Tesla using identical sequence settings and an intraindividual comparison. Materials and Methods: In 16 volunteers, myocardial first-pass perfusion imaging was performed at 1.5 Tesla (Magnetom Avanto) and 3 Tesla (Magnetom TIM Trio) after injection of 0.05mmol/kg body weight Gadobutrol using an accelerated saturation recovery TurboFLASH technique (GRAPPA;R=2) at 1.5 and 3 Tesla. Detailed sequence parameters (TR 2.3ms, TE 0.93ms, FA 15°, BW 780Hz/px)…
