目的：对比研究轴位和螺旋两种CT扫描方式对肺内孤立大体肿瘤体积(GTV)勾画的影响。方法将19例肺癌患者分别进行轴位(A)和螺旋(S)CT扫描。比较两种方法GTVA、GTVS大小、位置以及GTVA、GTVS匹配指数(MI)与体积的相关性。结果两种CT扫描方式的GTVA、GTVS大小及位置相关指标差异无统计学意义(P>0.05)；同时GTVA与GTVS的MI与肿瘤体积显著相关(r=0.898, P<0.05)。结论两种CT扫描方式所确定的肺内孤立灶GTV的MI与肿瘤体积大小显著相关,同时采用螺旋扫描速度更快,值得进行临床推广。
目的：對比研究軸位和螺鏇兩種CT掃描方式對肺內孤立大體腫瘤體積(GTV)勾畫的影響。方法將19例肺癌患者分彆進行軸位(A)和螺鏇(S)CT掃描。比較兩種方法GTVA、GTVS大小、位置以及GTVA、GTVS匹配指數(MI)與體積的相關性。結果兩種CT掃描方式的GTVA、GTVS大小及位置相關指標差異無統計學意義(P>0.05)；同時GTVA與GTVS的MI與腫瘤體積顯著相關(r=0.898, P<0.05)。結論兩種CT掃描方式所確定的肺內孤立竈GTV的MI與腫瘤體積大小顯著相關,同時採用螺鏇掃描速度更快,值得進行臨床推廣。

Objective To comparatively research the influence of axial position CT and spiral CT on delineation of isolated lung gross tumor volume (GTV). Methods A total of 19 patients with lung cancer received scanning by axial position (A) and spiral (S) CT. Size and location of GTVA and GTVS, and correlation between matching index (MI) of GTVA and GTVS and their volume were compared between the two methods. Results There were no statistically significant differences of size and location of GTVA and GTVS between the two CT scanning methods (P>0.05);while there was a remarkable correlation between MI of GTVA and GTVS and their volume (r=0.898, P<0.05). Conclusion Both CT scanning methods can show the significant correlation between MI of lung isolated GTV and volume, and spiral CT has faster scanning speed. It is worthy of clinical promotion.
