肺裂的显示对于确定肺部病变的位置，决定手术的方式、范围有着重要意义。但肺裂的ＣＴ影像受到邻近肺实质部分容积效应的影响，而未能很好显示。为了改善斜裂的显示，笔者对３５°倾斜轴薄层ＣＴ扫描进行了初步试验研究。通过对５０例正常肺不同倾斜轴ＣＴ扫描，探讨了常规扫描、２５°和３５°倾斜轴ＣＴ扫描对肺斜裂显示的价值。结果表明２５°和３５°倾斜薄层扫描对斜裂的显示明显优于常规ＣＴ标准扫描（Ｐ＜０．００１），３５°倾斜薄层扫描优于２５°倾斜薄层扫描，但无统计学上的意义（Ｐ＞０．０５）。
The manifestation of pulmonary fissure for determining the location of lung disease, determine the way the operation, the scope is of great significance. However, CT images of pulmonary fissures are affected by the volumetric effects of the parenchyma of the adjacent lung and are not well documented. In order to improve the display of oblique rupture, the author conducted a preliminary experimental study on thin layer CT scanning of 35 ° inclined axis. Through the CT scan of 50 different tilt axes of normal lungs, the value of routine scanning, 25 ° and 35 ° tilting axis CT scanning on the display of lung oblique rupture was discussed. The results show that the 25 ° and 35 ° oblique thin-slice scan shows better than the standard CT scan (P <0.001), 35 ° oblique thin-section scan better than 25 ° oblique thin-layer scan, but no statistical The significance (P> 0.05).
