【摘要】目的 探讨CT肺功能成像技术对早期尘肺的诊断价值.方法 利用表面遮盖显示(SSD) 3D-lung三维后处理技术、值域限定图像分割技术以及特殊的体积直方图软件1对30例早期尘肺患者和30例健康者的16排螺旋CT胸部平扫图像进行后处理.定性、定量比较二组的差异.结果 定性:对照组的3D-lung肺表面显示平滑的脏层胸膜;尘肺组显示肺表面局部凹陷.定量:尘肺组肺体积(3 730.4±603.6)cm3比健康者(4 114.8±742.2)cm3减小;而平均CT值尘肺组(-747.1±51.9)HU与对照组(-852.9±30.2)HU相比增大.2组数据差异均有统计学意义(P<0.05).尘肺组体积百分比与对照组相比稍有降低.结论 CT肺功能成像的多种技术能够定性、定量的观测到早期尘肺的纤维化及程度,结果客观、可靠,有较高的临床诊断价值.%To investigate the application of CT pulmonary function imaging in early diagnosis of pneumoconiosis. Methods The 16-slice spiral CT routine scan was used on 30 patients (observation object) with pneumoconiosis and 30 healthy persons. The tomography of images were post processed with surface shaded display (SSD) , threshold limits segmentation,and volume histogram analysis software. The differences between two groups were analyzed qualitatively and quantitatively. Results The qualitative analysis:the image of normal 3D-lung showed the normal lung reproduction and smoothing visceral
pleura,and pneumoconiosis group showed the local depression in the surface.
The

analysis;the
total

volume
of
pneumoconiosis group was (3730.4±603.6)cm,lower than that of the normal group,whereas the mean CT was higher than that of the normal group (P <0. 05). The VI of pneumoconiosis group was slightly decreased. Conclusion Multiple reconstruction techniques of CT pulmonary function imaging could observe pulmonary fibrosis and the degree of that by qualitative and quantitative methods. All results were objective and reliable. Multiple reconstruction technique of CT pulmonary function imaging is an effective tool in diagnosis of pneumoconiosis.
