目的：探讨 MRI 在卵巢肿瘤诊断及良恶性鉴别中的价值。方法分析经病理证实的卵巢肿瘤患者55例(共68个肿块) MRI 表现，并与病理及手术所见进行对照。结果55例中良性肿瘤33例，恶性肿瘤22例。肿瘤单侧或双侧受累(P =0.000)、内部信号(P =0.001)、肿块形态(P =0.000)、囊壁是否均匀(P =0.022)、与邻近脏器分界清楚与否(P =0.000)、盆腔淋巴结是否肿大(P =0.000)、肠道受累(P =0.004)、大网膜是否受累(P =0.011)及有无腹腔积液(P =0.004)方面的差异有统计学意义。肿瘤有无壁结节(P =0.057)对良恶性的鉴别无意义。卵巢恶性肿瘤，在显示盆腔淋巴结是否肿大(P =0.024)、大网膜受累(P =0.026)方面MRI 表现与手术所见差异有统计学意义；邻近脏器分界清楚与否(P =0.434)、腹腔积液(P =0.498)及肠道是否受累(P =0.112)方面无统计学意义。结论MRI 能够显示卵巢肿瘤的大小、形态和侵及范围，有助于区分肿瘤的良恶性，但在判断大网膜受累及盆腔淋巴结转移方面有一定局限性。

Objective To discuss the differential diagnosis value of MRI in the ovarian benign and malignant tumors.Methods 58 patients with ovarian tumors were pathologically confirmed.Additionally,the MRI manifestation and the operation and pathological results were analyzed and compared in detail.Results There were 33 benign tumors of all,and 22 were malignant.It had statistical-ly significant difference in the one or both ovaries affected (P =0.000),the internal signals (P =0.001),tumor shape (P =0.000), the cyst wall even or not (P =0.022),clear demarcation with near organs (P =0.000),the pelvic lymph node enlargement (P =0.000),intestinal involvement (P =0.004),the omentum majus affected (P =0.01 1),pyoperitoneum(P =0.004).There was no significant difference in whether the tumor had wall nodules or not (P =0.057).In the malignant tumors,MRI had statistical signif-icance in the pelvic lymph node enlargement (P =0.024),the omentum majus affected (P =0.026)compared with the operation re-sults.While there was no significant in the clear demarcation with near organs (P =0.434),Intestinal involvement (P =0.1 12)and pyoperitoneum (P =0.498)between MRI and opreation.Conclusion MRI could show the size,shape and invasive range of ovarian tumors,is helpful in distinguish the benign-malignant tumors.MRI had limitations in the pelvic lymph node metastases and the o-mentum majus affected or not.
