高分辨CT扫描技术在肺间质性病变中的应用价值

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.

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

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.
