| 摘 要： | 目的探讨64层螺旋CT超高分辨率扫描技术在肺部小结节诊断中的应用价值。方法对19例肺部小结节分别行常规扫描和局部靶扫描,进行512矩阵及超高分辨率1024矩阵重建,对比观察病灶分叶、毛刺、肿块密度及邻近胸膜改变,同时重建显示病灶整体形态,观察局部支气管的变化。结果常规高分辨率和超高分辨率在测量结节病灶的分叶深度有差异。8例动态增强扫描CT值的测量方面2者有差异。本组1例肺泡癌呈磨玻璃结节影,2者显示有差别,超高分辨率靶扫描更支持恶性诊断,更接近术后病理形态。在显示局部小气道明显狭窄、中断方面无明显差异;但在显示病灶内穿行的小气道轻度狭窄和通畅方面,40%的患者有差异。结论超高分辨率CT对肺小结节的立体形态、局部支气管改变显示更清晰,尤其对肺微小结节和局灶磨玻璃影的定性诊断具有重要价值。

| Abstract: | Objective To explore the application value of 64-spiral CT super-high resolution screening technique in diagnosis of pulmonary nodules.Methods Nineteen cases of patients with pulmonary nodules received routine screening,local target screening,and reconstruction with 512 matrix and super-high resolution CT(1 024 matrix).The changes of leaflet,rag,mass density and pleura nearby were compared.Meanwhile the total reconstruction shapes of nidi were displayed and the alternatives of local bronchial were observed.... |
