高分辨CT扫描技术在肺间质性病变中的应用价值

The application of High-resolution CT scanning in the diagnosis of interstitial lung disease

目的探讨高分辨CT扫描技术,对肺间质性病变的诊断价值。方法采用Philips MX8000 Dual螺旋CT机对30例肺间质性病变患者,行高分辨CT技术扫描。结果高分辨CT可清晰显示肺间质性病变的各种征象,肺间质性病变的高分辨CT主要表现为:(1)磨玻璃样密度影;(2)肺小叶间隔增厚;(3)小叶内间质增生;(4)网格状影;(5)胸膜下弧线影;(6)蜂窝肺;(7)牵拉支气管扩张;(8)胸膜增厚。病变分布以两肺中外带、胸膜下为主,病灶自肺尖向肺底逐渐加重,两肺基底部病变明显。结论高分辨CT扫描具有良好的空间分辨率,能细致、准确地反映肺间质病变的影像特征,对肺间质性病变具有重要的诊断价值。

Objective To study the value of HRCT scanning technology in improving the diagnosis of interstitial lung disease.Methods 30 cases of interstitial lung disease were scanned throng high-resolution CT with Philips MX8000 Dual CT machine.Results High-resolution CT can clearly show various signs of interstitial lung disease.The Interstitial lung disease of High-resolution CT Performance：（1） ground-glass opacity;（2） pulmonary interlobular septal thickening;（3） intralobular interstitial thickening;（4） grid-like shadow;（5） pleural shadow off the assembly line;（6） cell lung;（7） traction bronchiectasis;（8） pleural thickening.The lesion mainly distributes in lateral and under pleural of two lungs.The infection aggravates gradually from lung＇s point to lung＇s bottom.Conclusion The application of high-resolution CT scan in the interstitial lung disease has important diagnostic value.As the high-resolution CT scan with a good spatial resolution,can detail,accurately reflect the images of interstitial lung disease characterized.
