MSCT在新生儿Ⅲ型食管闭锁检查中的应用

摘要

目的 探讨MSCT在新生儿Ⅲ型食管闭锁检查中的应用价值.方法 回顾性分析25例经手术和病理证实为Ⅲ型食管闭锁新生儿的MSCT影像学资料,检查前充分准备及检查后的图像后处理功能,与手术结果相对照.结果 通过扫描前充分的准备及扫描后多平面重建(MPR)和三维表面遮盖显示(SSD)技术的应用,可清晰显示食管近端盲端以及近、远端食管盲端间的距离,还可以显示远端气管-食管瘘瘘管的开口位置、形态及管径,同时可见支气管树的形态以及肺内炎症.结论 MSCT充分的检查前准备及图像后处理功能,在先天性食管闭锁及气管-食管瘘的诊断中具有非常重要的应用价值.%Objective To study the value of MSCT in the diagnosis of neonatal type (Ⅲ) congenital esophageal atresia.Methods MSCT data of 25 cases with neonatal type (Ⅲ) congenital esophageal atresia confirmed by surgery and pathology were analyzed retrospectively.The full preparation before examination and the image post-processing function were checked,and MSCT data were compared with the findings of surgery.Results By full preparation and application of M PR,SSD technology after scanning,the esophageal proximal blind end,and the distance between the two esophageal blind ends were clearly displayed,furthermore,the opening position,morphology and diameter of the distal tracheoesophageal fistula were also showed,and bronchial tree morphology and inflammation in the lung can be visible.Conclusion MSCT full preparation and application of image post processing function are potential to the clinical diagnosis of congenital esophageal atresia and tracheoesophageal fistula.
