| 目的 探讨MRI诊断剖宫产术后瘢痕妊娠(CSP)的价值。方法 回顾性分析29例经手术证实为CSP患者的MRI资料,观察平扫及增强扫描特征。结果 29例患者MRI均清楚显示孕囊位于子宫前下段峡部瘢痕后方,20例呈囊状,增强扫描囊壁均匀强化,囊内容物无强化;9例呈不规则包块,增强扫描包块边缘呈不规则强化。23例孕囊向子宫肌层浸润的同时又向宫腔内生长;6例不同程度向子宫肌层浸润。子宫瘢痕均表现为条状等T1、短T2异常信号。结论 MRI平扫及增强扫描可明确诊断CSP。 |

| Objective To assess the value of MRI in the diagnosis of cesarean scar pregnancy (CSP). Methods Imaging data including plan scan and contrast-enhancecd MRI of 29 patients with CSP confirmed by curettage were retrospectively analyzed. Results The gestational sacs (GS) in all the 29 cases were clearly detected by MRI. GS were located at the scar of lower anterior uterus isthmus. GS presented as cystic and homogeneous enhancement mass without content enhancement in 20 cases. And GS displayed as irregular mass and the edge of irregular enhancement in 9 cases. GS was found within the myometrium with extension into the unterine in 23 cases, and within the myometrium in the remaining 6 cases. The cesarean scar were showed isointensity on T1WI and hypointensity on T2WI. Conclusion CSP has characteristic MRI findings. These features can provide useful informations for diagnosing CSP. |
