PDFAbstract
Objective To investigate the clinical diagnostic value of MRI combined with diffusion weighted imaging in patients with peritoneal metastasis. Methods A total of 56 cases of patients with peritoneal metastasis from February 2014 to March 2015 in our hospital were selected. All patients were diagnosed with MRI and MRI combined with diffusion weighted imaging. Results All the 56 suspected cases of peritoneal metastasis were examined by pathological examination and follow-up, 43 cases were confirmed diagnosed as peritoneal metastasis. The area under the DWI curve of MRI, MRI and ROC was 0.681 and 0.817, respectively, the difference was significant (P<0.05). The sensitivity, specificity, positive and negative predictive value of MRI for diagnosis of peritoneal metastasis were 85.7%, 53.8%, 85.7% and 53.8%, respectively. The sensitivity, specificity, positive and negative predictive value of MRI combined with DWI for peritoneal metastasis were 92.9%, 76.9%, 90.7% and 71.4% respectively. Conclusion MRI combined with diffusion weighted imaging has a higher clinical value than that of MRI alone in the diagnosis of peritoneal metastasis, which can be used in clinical application.
