【摘要】 目的:探讨卵巢病变的MRI特征以提高MRI在卵巢病变诊断中的作用。方法:分析100例经手术病理证实的卵巢病变患者MRI征象,其中卵巢囊肿5例,巧克力囊肿16例,囊腺瘤17例,卵巢癌35例,转移性肿瘤4例,畸胎瘤21例,其它2例。结果:卵巢囊肿、巧克力囊肿、囊腺瘤及畸胎瘤MRI的诊断符合率为96.67%。MRI对卵巢良恶性病变的鉴别诊断价值大,但较难区分卵巢原发肿瘤与转移性肿瘤。MRI可提供卵巢癌分期所需的信息,增强扫描进一步提高了MRI对卵巢癌的诊断及分期的准确性。结论:MRI能准确判断卵巢病变的性质,评估卵巢癌分期及手术可行性,应列为术前常规检查。更多还原

【Abstract】 Objective:To evaluate the MRI features and its value in the diagnosing of ovarian related diseases. Methods:The MRI features of 100 cases of surgically and pathologically proved ovarian diseases were enrolled and analyzed.The final diagnoses were 5 ovarian cysts,16 chocolate cysts,17 cystoadenoma,35 ovarian carcinoma,4 ovarian metastasis,21 teratoma and 2 other cases.Results:The accuracy of MRI in the diagnosing of ovarian cyst and chocolate cyst were 96.67%.MRI had a great value in differentiation from malignant and benign ovarian tumors,however it had certain limitation in differentiation the primary ovarian tumors and ovarian metastasis.Furthermore MRI was of great value in staging of ovarian carcinoma especially with MRI enhancement.Conclusion:MRI can accurately judge the character of ovarian diseases and evaluate its staging and the possibility of surgical remove of tumors.It should be listed as an examination routine before surgery.更多还原
