[Abstract] Objective: To evaluate the value of whole-body magnetic resonance diffusion weighted imaging (WB-DWI) in the screening of malignant tumor.Materials and Methods: Ten healthy volunteers and 36 patients of clinically suspected malignant tumors underwent WB-DWI and conventional MRI (scanning CT if it is chest disease) enhancing the scanning when necessary. The medical results of WB-DWI and MRI/CT were compared with the findings of pathological diagnosis and clinical comprehensive evaluations.Results: Twenty-nine of 36 patients were diagnosed as malignant tumors by final pathological endings, the others were benign lessions. Twenty-eight of 36 patients were diagnosed as malignant tumors by WB-DWI, 1 were misdiagnosed, 2 were missed. The primary lesions of 20 patients were diagnosed by WB-DWI. The sensitivity, specificity, youden’s index and agreement/consistency rate were 93.1%, 85.7%, 0.79 and 91.7%. Six of 7 patients, abnormality of benign lesions were found by WB-DWI.Conclusion: WB-DWI have certain value in the screening of malignant tumor.
