MRI在MRKH综合征诊断中的应用价值

目的：分析 MRK H 综合征的 MRI影像学特征,探讨 MRI在 MRK H 综合征临床诊断中的应用价值。方法回顾性分析经临床或手术证实为 MRKH 综合征的18例 MRI影像学特征。所有患者均行1.5T 或3.0T MRI 检查。患者取仰卧位,使用相控阵线圈对其进行检查。由2位经验丰富的放射科医生对所得 MRI图像进行评估并达成共识。评估内容包括阴道、子宫、卵巢的位置、形态,以及扫描范围内盆腔内的任何异常。结果18例中,除1例无子宫,1例为单侧(左侧)始基子宫,余16例均可见双侧始基子宫；33个始基子宫中,4个始基子宫分化成3层结构,即子宫内膜、结合带和肌壁。除1例双侧卵巢形态异常外,余17例患者双侧卵巢形态、大小及信号未见明显异常。所有患者阴道及宫颈缺如,其中1例阴道区可见囊性液体信号。结论 MRI在 MRK H综合征的明确诊断中发挥重要作用,可对患者手术方案的选择起指导作用。

Clinical value of MRI in patients with MRKH syndrome

Objective To evaluate the accuracy of preoperative MRI in the diagnosis of malformations associated with MRKH syndrome and identification of uterine endometrium to optimize the clinical management.Methods 1 8 females with primary amenor-rhea were studied with MRI performed with a 1.5T or 3.0T imager.All patients were examined in the supine position using a phased-array coil and underwent pelvic MRI.Two experienced radiologists evaluated all the examinations in consensus to assess the pres-ence,position and morphology of vagina,uterus,ovaries and any pelvic abnormalities.Results One or two rudimentary uteri were identified in 17 patients (94.4%).A total of 16 patients (88.9%)had bilateral rudimentary uteri,1 (5.6%)had unilateral rudimentary uteri(it was left sided).1 (5.6%)had no uterine remnants.4 (12.1%)of 33 uterine buds in 4 patients showed differentiation of the center of the uterus into three layer.Bilateral ovaries were present in 1 7 patients,and their shapes,sizes and signals are normal.The vagina and cervix were absent in all cases.Conclusion MRI is a useful diagnostic tool in the preoperative evaluation of MRKH syndrome and the endometrium to further optimize the treatment plan.
