摘要
目的:探讨MRI在诊断卵巢囊性畸胎瘤中的临床价值,为临床诊治提供参考依据。方法:选择2017年1月至2018年12月期间在我院经手术病理确诊为囊性畸胎瘤的24例患者以及40例卵巢巧克力囊肿患者作为本次研究对象。对卵巢囊性畸胎瘤与卵巢巧克力囊肿病变的MRI检查结果与手术结果进行分析与比较。主要对卵巢囊性畸胎瘤与卵巢巧克力囊肿的T1WI高信号区(相同点)在其他扫描序列下信号的特点(不同点),寻找鉴别卵巢囊性畸胎瘤与卵巢巧克力囊肿病变的扫描方法。结果:MRI对卵巢囊性畸胎瘤的诊断准确率为91.70%,对卵巢巧克力肿瘤的诊断准确率90.00%,差异无统计学意义(P>0.05);40例卵巢巧克力囊肿一共有64个囊性病灶,其中有50个病灶的STIR信号呈现被抑制的状态,这与卵巢囊性畸胎瘤的脂肪组织在STRI信号呈现被抑制的状态一致。结论:MRI对卵巢囊性畸胎瘤与卵巢巧克力囊肿进行鉴别时,可以观察MRI的T1WI、长T2WI信号,在STIR出现信号抑制时,对所显示的病灶内部的结果进行分析比较,同时对病灶进行增强扫描,对扫描结果与临床特点进行观察,对结果进行诊断鉴别。
Objective:To explore the clinical value of MRI in the diagnosis of ovarian cystic teratoma, and to provide reference for clinical diagnosis and treatment.Methods:From January 2017 to December 2018, 24 cases patients with cystic teratoma and 40 cases patients with ovarian chocolate cyst confirmed by surgery and pathology were selected as the subjects of this study. The results of MRI examination and operation of ovarian cystic teratoma and ovarian chocolate cyst lesions were analyzed and compared. The main purpose of this study was to identify cystic teratoma of ovary and chocolate cyst lesions of ovary by scanning the X signal region(same point) of cystic teratoma of ovary and chocolate cyst of ovary under other scanning sequences(different points).Results:The diagnostic accuracy of MRI for ovarian cystic teratoma was 91.70%, and for ovarian chocolate tumors was 90.00%, There was no significant difference in the data(P>0.05). There were 64 cystic lesions in 20 cases of ovarian chocolate cysts, of which 50 lesions showed suppression of STIR signal, which was consistent with that of STRI signal in adipose tissue of ovarian cystic teratoma.Conclusion:When chocolate cyst and cystic teratoma of ovary are differentiated by MRI, T1 WI and long T2 WI signals of MRI can be observed. When signal suppression occurs in STIR, the results of the internal lesions displayed are analyzed and compared. At the same time, the lesions are scanned by enhanced scanning, the results of scanning and clinical characteristics are observed, and the results are diagnosed and differentiated.
