摘要
目的分析MRI在卵巢成熟性畸胎瘤诊断中的应用价值。方法搜集我院经手术病理证实的卵巢畸胎瘤46例共49个卵巢成熟性畸胎瘤,对其MRI表现进行分析。结果 46例患者中共49个卵巢成熟性畸胎瘤,其中左侧卵巢24例,右侧卵巢19例,双侧卵巢3例。肿瘤内成分不同,MR信号表现不同,脂肪组织T1WI及T2WI表现为高信号,脂肪抑制呈低信号,化学位移成像同相位表现为高信号,反相位信号有不同程度的衰减,头发、骨骼组织表现为低信号。结论 MRI能较好地显示卵巢成熟性畸胎瘤的内部结构及成分,化学位移成像对发现肿瘤内脂肪成分敏感,具有良好的诊断价值。
Objective Analyzing MRI value of diagnosing ovarian mature teratoma. Methods Collecting 49 ovary mature teratomas in 46 patients who are confirmed by surgery and pathology from this hospital,and analyzing their MRI findings. Results All49 ovary mature teratomas from 46 patients suffered from ovarian tumor including 24 in left ovary,19 in right ovary and 3 in both ovaries. MR signals differ in various tumor ingredients. Fat tissues like T1 WI and T2 WI are high signal while fat suppression is low signal; the in phase in chemical shift image is high signal while out of phase is lower signal to some extent,such as hair and bone tissues. Conclusion MRI can well display internal structure and ingredients in ovarian mature teratoma,and chemical shift imaging are sensitive to finding fat ingredients in tumors and has great diagnosis values.
