目的探讨剖宫产后子宫切口瘢 痕妊娠的MRI影像学特点。方法 经手术或 病理证实瘢痕妊娠患者25例，回顾性分析 MRI及临床资料，总结其MRI影像特征。结 果 25例中有7例呈囊状信号特征，18例表 现为混杂信号包块影；25例中有3例较小 妊娠囊完全位于瘢痕区子宫肌层，6例向 宫腔内生长，16例向子宫前壁肌层浸润生 长并向宫腔内生长，局部子宫峡部前壁明 显变薄；25例疤痕妊娠患者，18例先药物 治疗，再在超声监测下行清宫术，5例先 行子宫动脉栓塞术，然后行清宫术，另 外2例采用腔镜下子宫切开取胚术。结论 MRI能为临床治疗方案的选择提供重要的 参考价值。

Objective To analyze the magnetic resonance imaging(MRI )features of cesarean scar pregnancy(CSP). Methods The MRI features 25 patients with CSP confirmed by clinic and pathology after cesarean section were retrospectively analyzed. Results All gestational sacs of the 25 CSP patients were clearly demonstrated on MRI.The gestational sacs were cystic(7/25) or heterogeneous(18/25)，located within the uterine cavity (6/25) or deeply implanted in the scar(19/25).Suction and curettage were performd in 18/25, uterine artery embolization in 5/25 and laparoscopic operation in 2/25. Conclusion CSP has its unique findings on MRI, these specific features can provide useful information in the management of CSP.
