目的：探讨卵巢肿瘤的MRI诊断价值。材料与方法：回顾性分析17例经手术／病理证实的卵巢肿瘤的MRI表现（包括T1、T2及静脉注射Gd－DTPA后T1三相）。结果：3例卵巢囊肿表现为单个或多个园形、椭园形等或稍长T1及长T2像；1例巧克力囊肿呈短T1长T2像；1例畸胎瘤呈实性，有脂肪及钙化信号。12例恶性肿瘤中2例转移瘤均表现等T1长T2肿块，Cˉ后增强，并均有腹水征。10例原发性卵巢癌中9例信号不均匀，呈囊实性肿块或肿块内不规则坏死液化。3例侵及周围脂肪层或盆隔，Cˉ更清楚。另1例卵巢癌术后MR复查，腹腔内广泛种植。结论：MRI诊断卵巢囊肿或良性肿瘤与B超、CT的价值相似；对恶性卵巢肿瘤的诊断与TNM分期明显优于CT或B超，值得推广。
Objective: To investigate the diagnostic value of MRI in ovarian tumors. MATERIALS AND METHODS: The MRI findings (including T1, T2, and T1 three phases after Gd-DTPA injection) of 17 surgically / pathologically confirmed ovarian tumors were retrospectively analyzed. Results: Three cases of ovarian cysts showed single or multiple round, oval or slightly longer T1 and long T2 images. One case showed short T1 long T2 images of chocolate cysts. One case of teratoma was solid with fat And calcification signal. Two of the 12 cases of malignant tumors showed long T1-like tumors with a long T1 mass, which were enhanced after Cˉ and had signs of ascites. In 10 cases of primary ovarian cancer, 9 cases of non-uniform signal was cystic solid mass or irregular necrosis liquefaction. 3 cases of invading the surrounding fat layer or basin, C ˉ clearer. Another case of postoperative ovarian cancer MR review, widespread intraperitoneal implantation. Conclusion: The diagnostic value of MRI in diagnosis of ovarian cyst or benign tumor is similar to that of B ultrasound and CT. The diagnosis and TNM staging of malignant ovarian tumor is superior to CT or B ultrasound, which is worthy of popularization.
