【摘要】：目的:探讨产前超声及MRI在诊断胎儿颅后窝异常中的应用价值及临床意义。方法:对2011年1月—2012年12月于我院行超声检查拟诊胎儿颅后窝异常者进行回顾性分析,随访其产前超声表现、MRI检查结果、妊娠结局及产后影像学资料。结果:研究期间超声检出胎儿颅后窝异常并同时进行MRI检查共27例,其中18例(66.7%)MRI证实了超声诊断,另9例MRI显示胎儿颅后窝结构正常,产后随访亦未见异常。其中11例活产,10例进行了产后MRI检查,其中5例(50%)产前、产后MRI结果完全相符,2例(20%)两者诊断不相符,另3例(30%)产后MRI补充了新的诊断。结论:产前超声对发现胎儿颅后窝异常有重要的临床意义,MRI对病变的显示效果及诊断符合率较超声更精确,可作为重要的验证和补充诊断手段,但应重视产后的影像学随访观察。
[Abstract]:Objective: To investigate the prenatal ultrasound and MRI fossa and its clinical significance in the diagnosis of abnormal value of fetal posterior fossa. Methods: January 2011 - December 2012 anomaly in our hospital ultrasound examination for suspected fetal posterior who were retrospectively analyzed and followed the prenatal ultrasound, MRI examination results, the outcome of pregnancy and postpartum imaging results: during the study period. Ultrasound detection of fetal posterior fossa abnormalities and MRI was performed in 27 cases, including 18 cases (66.7%) MRI confirmed the ultrasound diagnosis, the other 9 cases MRI showed fetal posterior fossa structures, postpartum follow-up showed normal. 11 cases of live births, 10 cases of postpartum MRI check, in which 5 cases (50%) prenatal, postpartum MRI were consistent in 2 cases (20%), the diagnosis does not match, the other 3 cases (30%) postpartum MRI adds new diagnosis. Conclusion: prenatal ultrasound has important clinical significance for the detection of fetal anomalies of posterior fossa lesions on MRI. The display effect and diagnostic coincidence rate are more accurate than ultrasound, which can be used as an important means of verification and supplementary diagnosis. However, attention should be paid to the follow-up and observation of postpartum imaging.
