Evaluation of a Subject specific dual-transmit approach for improving B(1) field homogeneity in cardiovascular magnetic resonance at 3T

BACKGROUND: Radiofrequency (RF) shading artifacts degrade image quality while performing cardiovascular magnetic resonance (CMR) at higher field strengths. In this article, we sought to evaluate the effect of local RF (B(1) field) shimming by using a dual-source–transmit RF system for cardiac cine i...
