Synopsis

The purpose of this study to assess image quality and T1 value value between variable flip angle (VFA-T1) and StarVIBE (StarVIBE-T1) methods using breath-holding and free breathing, respectively. Compared with VFA-T1 method, StarVIBE-T1 had better image quality, including overall image quality, blurring, and clearer edge of lesions, especially for the patients without breath-holding. The T1 values from the two methods had high correlation and moderate agreement.
