Introduction : To quantitatively evaluate the improvement of image quality and the consistency of systolic function calculation in CMR cine images with dual-source RF transmission (Tx) at 3.0 T scanner.Method : After written informed consent was obtained, fourteen healthy volunteers (9 male, 37 ± 11 yrs) were scanned at 3.0 T MR (Achieva, Philips, Netherlands).B1 calibrations were performed with echo planar imaging to acquire B 1 maps, which were scaled as a percent of flip angle to quantitatively assess the homogeneity of B 1 field.Balanced-turbo field echo (B-TFE) sequence was applied to obtain cardiac cine images.
