Abstract: Objective To estimate the value of diffusion weighted imaging with background body signal suppression(DWIBS)in tumors of intestinal tract and metastasis.Methods 15 cass with tumors of intestinal tract underwent MRI and DWIBS examinations.Four of them underwent CT scan.Results All primary tumors were showed by conventional MR sequences and DWIBS.DWIBS showed that 4 cases had the invasion of placenta percreta,5 cases had transcoelomic metastasis in abdominal cavity and 5 cases had lymphatic metastasis,while the conventional MR sequences showed the invasion of placenta percreta in 10 cases,the invasion of fat interspace in 8 cases,transcoelomic metastasis in abdominal cavity in 3 cases and lymphatic metastasis in 3 cases.Conclusion DWIBS is better than the conventional MR sequences and CT in detecting the primary tumor of intestinal tract,transcoelomic metastasis in abdominal cavity and lymphatic metastasis.However,the conventional MR sequences and CT is better than DWIBS in detecting the invasion of placenta percreta and fat interspace.
