卵巢肿瘤的的MRI诊断与鉴别诊断

MRI Diagnose and Differential Diagnose of Ovarian Tumor

目的探讨MRI平扫及弥散加权成像对卵巢良恶性肿瘤的诊断价值。方法回顾性分析46例经手术和病理证实的卵巢良恶性肿瘤的MRI资料,与病理结果相对照。结果术前诊断卵巢良性肿瘤27例,恶性肿瘤19例;术后诊断良性肿瘤28例,恶性肿瘤18例。结论 MRI具有良好的组织对比分辨率,平扫能显示病变的分布、形态、大小、肿瘤成分、边界,而弥散加权成像有助于区分肿瘤的良恶性。

Objective To evalute the value of MRI and diffusion-weighted magnetic resonance imaging （ DWI） in the diagnosis of benign and malignant ovarian tumors. Methods Conventional magnetic resonance imaging and diffusion-weighted magnetic resonance imaging findings in 46 cases of ovarian tumors firmed by operation and surgical-pathology were analyzed retrospectively. Results Of 46 cases ovarian tumors,in which 27 cases were benign tumors and 19 cases were malignant tumors before operation,28 cases were benign tumors and 18 cases were malignant tumors were confirmed by operation and surgical-pathology. Conclusion MRI have satisfactory constitution resolution,which can display the distribution,size,morphology,composition, margin of ovarian tumors,while DWI can help to determine the feature of benign and malignant ovarian tumors.
