高分辨力CT的应用极大地改善了肺部弥漫性疾病的诊断 ,能够更好地显示受累肺实质严重的区域和影像学特征 ,但是扫描层间距为 10～ 2 0mm时 ,可能会遗漏局灶性的肺部异常。多层螺旋CT能够将扫描的原始数据进行轴位的HRCT重建和在工作站进行冠状位图像的重建 ,是一种新的诊断技术
The use of high-resolution CT has greatly improved the diagnosis of diffuse lung disease, and can better show the parenchymal lung involvement and imaging features, but the foci may be missed when the scan interval is between 10 and 20 mm Sexual lung abnormalities. Multislice spiral CT is a new diagnostic technique that can reconstruct the axial scanned HRCT data and reconstruct coronal images at the workstation
