Conventional Whole-Body DWI that consists of several sequential stations often troubled geometric distortions and signal drops in areas with strong susceptibility, such as the neck and lumbar vertebra. The aim of this study was to propose a new WBDWI protocol and post process deformation algorithm to get distortion free whole body images. Consistently good results were received and in helps to diagnose several cases of tumors that were previously unclear to the volunteers and patients.
