Multi-transmit (i.e. 2-channel 2-port) and multi-phase transmission (i.e. 2-channel 4-port) techniques may be one of the solutions for improving image quality and capability of 3T MR system not only chest MR imaging, but also other body MR imaging. We hypothesized that multi-phase transmission RF system could improve B1 inhomogeneity and image quality on basic and clinical studies as compared with single-transmit and multi-transmit RF systems. The purpose of this study was to directly and prospectively compare B1 homogeneity and image quality of chest MR imaging among three different RF systems on 3T MR system.
