目的：探讨宝石能谱CT在小儿肺静脉异位引流中应用价值。方法回顾分析16例手术证实肺静脉异位引流患儿资料,所有患儿均使用低计量造影剂0.8~1.0 ml/kg,常规扫描后图像进入能谱界面处理,找出最佳单能图像,并行多平面重组(MPR)、薄层最大密度投影(MIP)和容积重建(VR)等后处理,并与彩超进行对照研究。结果所有患儿宝石能谱CT均显示肺静脉回流异常,利用宝石能谱最佳单能图像重建图像,16例均完整显示引流静脉行径,16例患儿引流位置诊断明确,显示率均高于彩超。重建图像能直观明确显示引流静脉的整体形态。结论小儿肺静脉异位引流利用宝石能谱CT检查,使用低剂量造影剂,用50~55 Kev单能图像重建,能很好的显示肺静脉异位引流细节,减少造影剂对小儿肾功能损害。
目的：探討寶石能譜CT在小兒肺靜脈異位引流中應用價值。方法迴顧分析16例手術證實肺靜脈異位引流患兒資料,所有患兒均使用低計量造影劑0.8~1.0 ml/kg,常規掃描後圖像進入能譜界麵處理,找齣最佳單能圖像,併行多平麵重組(MPR)、薄層最大密度投影(MIP)和容積重建(VR)等後處理,併與綵超進行對照研究。結果所有患兒寶石能譜CT均顯示肺靜脈迴流異常,利用寶石能譜最佳單能圖像重建圖像,16例均完整顯示引流靜脈行徑,16例患兒引流位置診斷明確,顯示率均高于綵超。重建圖像能直觀明確顯示引流靜脈的整體形態。結論小兒肺靜脈異位引流利用寶石能譜CT檢查,使用低劑量造影劑,用50~55 Kev單能圖像重建,能很好的顯示肺靜脈異位引流細節,減少造影劑對小兒腎功能損害。

Objective To explore the of application value precious stones energy spectrum CT in children with pulmonary vein ectopic drainage. Methods Retrospective analysis of 16 cases of confirmed pulmonary vein ectopic drainage operating data, low measuring contrast agents should be used in all children with 0.8 to 1.0 ml/kg, routine scan image spectrum into the interface processing, can find out the best single image, the parallel multi planar reconstruction (MPR), thin layer maximum density projection (MIP) and volume reconstruction (VR), and other post-processing, and compared with colour to exceed control study. Results All children with stones energy spectrum CT showed abnormal pulmonary vein reflux, energy spectrum can be the best single image reconstruction images using gems, 16 cases were showed venous drainage, drainage position clear diagnosis, 16 cases showed rates were higher than in colour to exceed. Reconstruction image can show the overall form of venous drainage clear intuitive. Conclusion Pediatric pulmonary vein ectopic drainage use of precious stones energy spectrum CT examination, use of low dose contrast agents, with 50 to 55 kev single image reconstruction, can display the pulmonary vein ectopic drainage good details, reduce the contrast of pediatric renal damage.
