儿童肺不发育-发育不良综合征的影像学诊断

Imaging Diagnosis of Pulmonary Agenesis-hypoplasia Complex in Children

目的分析并总结儿童肺不发育-发育不良综合征的胸部影像学诊断。资料与方法回顾性分析24例肺不发育-发育不良综合征患者的胸部计算机X线摄影(CR)、多层螺旋CT(MSCT)增强扫描影像资料。MSCT肺部常规层厚8 mm,在16层螺旋CT机行层厚2 mm、层间隔1 mm重组,行多平面重组(MPR)、最大密度投影(MIP)、最小密度投影(MinIP)、容积再现(VR)后处理重组。结果24例病变MSCT后处理重组全部清晰显示并诊断,其中肺缺如2例,肺不发育3例,肺发育不全19例。结论MSCTA及后处理重组对于诊断肺不发育-发育不良综合征具有重要价值。

Objective To introduce the imaging diagnosis of pulmonary agenesis-hypoplasia complex in children. Materials and Methods 24 patients were all examined by plain chest film and enhanced muhisliee CT （MSCT）. All patients were scanned on Siemens 16-slice scanner, using 8 mm collimation, and reconstructed at 2 mm intervals and 1 mm thickness. Multiplanar reconstruction （MPR）, Maximum intensity projection （MIP）, Minimum intensity projection （MinIP） and Volume-rendered image （VR） were all reconstructed at workstation. Results On CT reconstruction images, all 24 patients with pulmonary agenesis-hypoplasia complex were demonstrated clearly. There were 2 patients with pulmonary agenesis, 3 patients with pulmonary aplasia and 19 patients with pulmonary hypoplasia. Conclusion MSCTA with reconstruction images has great value on diagnosing pulmonary agenesis-hypoplasia complex.
