目的：探讨剖宫产后子宫切口妊娠（cesarean scar pregnancy ，CSP）的MRI表现及诊断价值。方法回顾性分析8例经手术病理证实的子宫切口妊娠患者的M RI表现，将M RI影像表现与手术及病理结果进行比较，总结其M RI特点。结果8例子宫切口妊娠M RI均清楚显示孕囊，位于子宫峡部前壁切口瘢痕处，孕囊向子宫肌层浸润同时向宫腔内生长，局部子宫峡部前壁明显变薄。其中7例孕囊为圆形或椭圆形，呈T1 WI低信号、T2 WI高信号囊状信号特征，囊壁光滑。其中1例孕囊表现为包块影，形态欠规则，T1 WI上呈等信号，T2 WI呈混杂信号，包块内及宫腔内见少量积血。结论子宫切口妊娠M RI表现具有一定特点，对临床早期明确诊断及治疗具有重要价值。

Objective To investigate the MRI features and diagnostic value of cesarean scar pregnancy (CSP) .Methods The retrospective analysis was performed on 8 cases with the MRI features of CSP proved by operation and pathology ,and comparison was made between the MRI findings and surgical results .Results All gestational sacs (8) located at the lower anterior uterus were clearly displayed by MRI .Gestational sac was found partially within the myometrium with extension into the uterine cavity .The anteior wall of isthmus uteri became thinner .In the 7 of the 8cases ,gestational sac presented as round or oval with smooth margin ,the mass was shown homogeneous hypointensity on T 1 WI and hyperintensity on T2WI .In the remaining 1 of the 8 cases ,gestational sac was shown as irregular mass ,which showed isointensity on T1WI and heterogeneous intensity on T2WI .A small amount of hemorrhage within the cystic mass and uterus cavity can be seen . Conclusion CSP has its specific features on MRI .Theses specific features can provide useful information in the dignosis and treatment of CSP .
