We have developed a new black-blood imaging with radial scan (multi vane) method and improved motion sensitized driven equilibrium (iMSDE). In this study, we changed the following parameters [refocusing flip angle (RFA), TE prep, flow velocity encoding (VENC)]. In addition, we measured SNR and Contrast ratio (CR) to optimize image quality. As RFA increased in radial scan with iMSDE, SNR of muscle rose gently and CR increased. With the extension of TE prep, SNR of muscle declined and CR also declined. As VENC decreased, CR rose gently. There was a significant difference compared with the conventional method.
