Diffusion Weighted whole body Imaging with Background body signal suppression with three b value for tumorlike lesion detection in abdomen

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.
