目的：探讨 CT 扫描层厚、增强与否对Ⅰ期非小细胞肺癌（NSCLC）三维最大径、体积及质量的影响。方法：92例Ⅰ期NSCLC患者，其中76例在平扫基础上进行了增强扫描；扫描数据传至CT后处理工作站，采用计算机辅助诊断软件描绘并分割病灶，分别自动测量2 mm、7 mm层厚及7 mm增强前后病灶的最大径d（mm）、体积V（mm3）、质量m（g），计算各均值及方差，运用配对 T 检验评价不同层厚、增强与否对肿瘤的三维测量结果有无统计学差异。结果：2 mm、7 mm层厚CT扫描条件下，d、V、m的测量结果具有显著统计学差异（P<0.05）；7 mm层厚扫描条件下，CT增强前后d、V的测量无显著统计学差异（P>0.05），m的测量具有显著统计学差异（P<0.05）。结论：胸部CT扫描2 mm、7 mm层厚的选取对Ⅰ期NSCLC三维最大径、体积及质量的测量结果具有一定的影响；CT增强可影响肿瘤的质量测量评价。
目的：探討 CT 掃描層厚、增彊與否對Ⅰ期非小細胞肺癌（NSCLC）三維最大徑、體積及質量的影響。方法：92例Ⅰ期NSCLC患者，其中76例在平掃基礎上進行瞭增彊掃描；掃描數據傳至CT後處理工作站，採用計算機輔助診斷軟件描繪併分割病竈，分彆自動測量2 mm、7 mm層厚及7 mm增彊前後病竈的最大徑d（mm）、體積V（mm3）、質量m（g），計算各均值及方差，運用配對 T 檢驗評價不同層厚、增彊與否對腫瘤的三維測量結果有無統計學差異。結果：2 mm、7 mm層厚CT掃描條件下，d、V、m的測量結果具有顯著統計學差異（P<0.05）；7 mm層厚掃描條件下，CT增彊前後d、V的測量無顯著統計學差異（P>0.05），m的測量具有顯著統計學差異（P<0.05）。結論：胸部CT掃描2 mm、7 mm層厚的選取對Ⅰ期NSCLC三維最大徑、體積及質量的測量結果具有一定的影響；CT增彊可影響腫瘤的質量測量評價。

Objective:To assess the effect of computed tomographic (CT) section thickness, CT enhancement on stageⅠnon-small cell lung cancer (NSCLC) measurements calculated with three-dimensional methods. Methods:92 patients of the stageⅠNSCLC were analyzed on CT scan with 2 mm, 7 mm CT section thickness;of which 76 had 7 mm CT section thickness enhanced scanning. The data were sent to the CT post-processing workstation, the lesions were automatically delineated by using computer-aided diagnostic software. The maximum diameter: d (mm), volume: V (mm3), mass: m (g) of the lesions were measured on each section thickness, before and after enhancement. Means and variances were calculated, and the differences across the two section thicknesses, before and after enhancement were studied by using pair T-test. Results: Differences in the means of d, V, m were significant between a section thickness of 2 and 7 mm (P<0.05); Differences in the means of d, V were not significant between 7 mm plain CT and contrast enhancement (P>0.05), while differences in the means of m were significant (P<0.05). Conclusion:Section thickness of 2 and 7 mm selection on chest CT scan had a certain influence on maximum diameter, volume and mass measurement result of stage Ⅰ NSCLC; CT enhancement could affect measurement result of mass.
