Application of whole-body diffusion-weighted imaging on gastrointestinal malignant tumors
DOI:10.12015/issn.1674-8034.2016.11.010.
| [Abstract] Objective: To discuss the technical feasibility of whole body diffusion weighted imaging (WB-DWI) on 3.0 T magnetic resonance imaging (MRI).To evaluate the auxiliary diagnostic role of WB-DWI in patients with gastrointestinal malignant tumors by detection of primary tumors and metastasis.Materials and Methods: Nineteen patients with gastrointestinal malignancy operation history were enrolled in our study. All patients received whole body MRI examination. The magnetic resonance (MR) examination was performed on 3.0 T MR scanner using coils. The images were reviewed separately by two radiologists.Results: A total of 8 metastatic lesions in 4 regions of 7 patients were detected by whole body DWI. One patient with stomach cancer had both liver metastasis and lymph nodes metastasis.Conclusions: The WB-DWI images that meet the diagnostic needs can be obtained on 3.0 T MRI. WB-DWI reveals excellent detection of metastasis of gastrointestinal malignant tumors. |
