The Diagnostic Efficiency of IVIM-DWI in Benign and Malignant Ovarian Tumors and the Correlation with Tumor makers and clinicopathological Factors.

The aim of this study was to investigate the value of introvoxel incoherent motion diffusion-weighted magnetic resonance imaging (IVIM-DWI) in the diagnosis of benign and malignant ovarian tumor. There were 108 patients with ovarian tumors who were selected to compare the differences of IVM-DWI parameters between benign and malignant tumors. The results showed that the IVIM-DWI parameters including apparent diffusion confident (ADC), slow diffusion confident (Disown) and fast diffusion confident score (f value) of malignant tumor were lower than that of benign tumor (P$0. 05). The area under ROC curve of ADC, Slow and f value in the diagnosis of malignant ovarian tumor were 0. 816, 0. 915 and 0. 852, respectively (P$0. 05). ADC and Disown were negatively correlated with carbohydrate antigen 125(CA125) (r= -- 0. 457 and --0. 553, P$0. 05). The ADC in patients whit Hal stage was significantly lower than that of patients I -- (P$0. 05). In a word, IVIM-DWI parameters have a certain value in the diagnosis of benign and malignant ovarian tumors, and the ADC, Do levels are corrected with CA125 and Hal stage of patients with malignant tumors.
