The purpose of this study was to evaluate image quality of diffusion weighted whole body Imaging with background body signal suppression (DWIBS) sequence using different b values (b=0,800 and b=0,800,1500) for predicting tumor or tumorlike lesions in abdomen. The results showed index ADC image with b=0,800 depicted more lesions than b=0,1500, including false positive lesions. The ADC value of b=0,800, 1500 is less than that of b=0, 800, indicating tumor’s precise ADC value is lower than we thought before.
