Synopsis

Keywords: Kidney, CEST & MTRespiratory movement is the main reason for upper and middle abdominal organ movement, which significantly affects the quality of MR imaging.This study aims to analyze the influence of renal motion amplitude on renal APT imaging through free breathing (FB), and breath holding (BH) based on multi-phase balanced turbo fast field echo (B-TFE). The results showed that renal motion amplitude was negatively correlated with APTw image quality scores. The renal motion amplitude of bilateral kidneys of BH mode was significantly reduced compared with FB, and the APT image quality of BH mode was better.
