摘　　要：目的为了增强在卵巢中存在的卵泡膜细胞瘤的临床MRI的综合诊断效果,对该表在进行MRI影像学检查中的主要特征。方法随机地抽选出在该院中自2009年2月—2016年2月由病理学确诊的共36例在卵巢中存在的卵泡膜细胞瘤的患者,然后采用回顾性地分析方法进行全部患者的MRI检查特征的统计与分析过程。结果在36例患者中共有29例患者属于一侧的肿瘤,而共有7例患者属于两侧的肿瘤。57个病变部位都大部分属于实性肿瘤,其中典型的低等信号T2W共有45个(78.95%),其他12个(21.05%)属于在大部分的低等信号中存在少量片状或是絮状的稍高等信号;而增强扫描显,其他(19.30%)属于在大部分的轻微程度的强化中存在局部区域的显著强化表现。全部的研究对象中共有子宫内膜发生增厚的5例(13.89%),产生腹水的共有10例(27.78%),雌激素E2升高的共有25例(69.44%)。结论在卵巢中存在的卵泡膜细胞瘤的MRI特征主要包含特定的性质,即T2W序列出现显著的低等信号与轻微程度的强化,这些性质能够促进其准确地进行诊断。Objective To study the main features of MRI imaging examination in order to enhance the general diagnostic effect of ovarii theca cell tumor. Methods 36 cases of patients with theca cell tumors diagnosed by pathology in our hospital from February 2009 to February 2016 were randomiy selected and the MRI examination features of all patients were counted and analyzed. Results In the 36 cases of patients, there were 29 cases with unilateral tumors and 7 cases with bilateral tumors, and most of the 57 lesion sites were the solid tumors, including 45 low-graded signals T2W, accounting for 78.95% and the other 12 （21.05%） had few slightly high-graded signals in slice shape or flocculatidn shape, and the enhancement scanning showed that 19.30% had the obvious enhancement manifestation in local region, and there were 5 cases with endometrial thickening, accounting for 13.89%, 10 cases with ascites, accounting for 27.78%, 5 cases with female hormone E 2 elevation, accounting for 69.44%. Conclusion The MRI features of ovarii theca cell tumor in ovary mainly include specific nature, namely obviously low-graded signals and mild degree of enhancement in T2W sequence, which can promote the accurate diagnosis.
