摘　　要：目的探讨出血梗死性卵巢蒂扭转MR不同序列表现特点。方法选取我院经手术病理证实的出血梗死型卵巢蒂扭转患者10例,回顾性分析其MR序列特征。结果10例卵巢蒂条状增粗,T2W低信号,T1W稍高信号,增强扫描T1W无强化;扭转蒂周围脂肪间隙均见不同程度渗出;8例病灶壁-蒂局部T2W低信号;6例病灶壁-蒂局部T1W等或高信号,增强扫描T1W抑脂无强化。结论出血梗死型卵巢蒂扭转MR有特殊表现,不同序列对诊断出血梗死性卵巢蒂扭转有重要参考价值。Objective To explore characteristics of ovary pedicle torsion with hemorrhagic infarction and relative lesions in different magnetic resonance image (MRI) sequences. Methods 10 patients underwent MR examination and were confirmed by operation and pathology,their data and MR characteristics were retrospectively analyzed.Results The ovary pedicles of all cases were obviously thicker,the signals on T1WI were mild high and low on T2WI,and there were no contrast enhancement,the surrounding fat gaps of torsion pedicles appeared different extent effusion.In relative lesions of ovary pedicle torsions,the lesion walls had regionally the hypointensities on T2WI in 8 cases,and locally isointensities or hyperintensities in 6 ones,all lesions had no contract enhancement. Conclusion There are MR special appearances in hemorrhagic infarction ovary pedicle torsion and the relative lesions,further important reference values are obtained using the different MR sequences.
