[摘要] 目的 探討高分辨薄層CT用于早期肺腺癌診斷篩查中的效果。方法 方便選擇2017年1月—2019年8月經該院病理學確診治療的早期肺腺癌患者70例作為對象，隨機數字表分為對照組（n=35）和觀察組（n=35）。對照組給予常規(guī)CT檢查，觀察組給予高分辨薄層CT檢查，比較兩組不同CT掃描方式下腫瘤征象顯示率，圖像質量以及診出率。結果 觀察組中棘突征檢出率為85.71%，對照組為57.14%（χ2=6.396）、觀察組中毛刺征為71.43%，對照組為51.43%（χ2=5.786）、觀察組中鈣化征為45.71%，對照組為11.43%（χ2=4.935）、觀察組中血管集束征為74.29%，對照組為48.57%（χ2=7.972）、觀察組中分葉征為85.71%，對照組為60.00%（χ2=4.997）、觀察組中空泡征為28.57%，對照組為8.57%（χ2=8.016）、觀察組中胸膜凹陷征為77.14%，對照組為45.71%（χ2=6.472）。觀察組中對于棘突征、毛刺征、鈣化征、血管集束征、分葉征、空泡征、胸膜凹陷征等顯示率均高于對照組（P<0.05）。觀察組的圖像總優(yōu)良率為94.28%，對照組的總優(yōu)良率為77.14%，觀察組的圖像總優(yōu)良率明顯高于對照組（χ2=7.371，P<0.05）;參照病理學檢測結果，觀察組的診出率為97.14%，對照組的診出率為71.43%，觀察組的診出率明顯高于對照組（χ2=6.827，P<0.05）。結論 將高分辨薄層CT用于早期肺腺癌診斷篩查中，可以清晰看到腫瘤，病灶區(qū)內部結構等特征，提高CT的成像質量，提高診出率。

[Abstract] Objective To explore the effect of high-resolution thin-layer CT in the diagnosis and screening of early lung adenocarcinoma. Methods Seventy patients with early-stage lung adenocarcinoma diagnosed and treated by the pathology of the hospital from January 2017 to August 2019 were convenient selected as subjects. The random number table was divided into the control group （n=35） and the observation group （n=35）. The control group was given conventional CT examination， and the observation group was given high-resolution thin-layer CT examination. The tumor sign display rate， image quality， and diagnosis rate were compared between the two groups under different CT scans. Results The detection rate of spinous process in the observation group was 85.71%， 57.14% in the control group （χ2=6.396）， the glitch sign in the observation group was 71.43%， the control group was 51.43%（χ2=5.786）， and the calcification in the observation group was 45.71%， the control group was 11.43%（χ2=4.935）， the vascular bundle sign in the observation group was 74.29%， the control group was 48.57%（χ2=7.972）， the leaf splitting sign in the observation group was 85.71%， and the control group was 60.00%（χ2=4.997）， the hollow sign in the observation group was 28.57%， in the control group was 8.57%（χ2=8.016）， in the observation group， the pleural depression was 77.14%， and the control group was 45.71%（χ2= 6.472）. In the observation group， the display rates of spinous process sign， glitch sign， calcification sign， vascular bundle sign， defoliation sign， vacuole sign， and pleural depression sign were all higher than those in the control group（P<0.05）. The overall excellent and good rate of the observation group was 94.28%， and the total excellent and good rate of the control group was 77.14%. The overall excellent and good rate of the observation group was significantly higher than that of the control group（χ2=7.371， P<0.05）. The diagnosis rate in the group was 97.14%， and that in the control group was 71.43%. The diagnosis rate in the observation group was significantly higher than that in the control group（χ2=6.827， P<0.05）. Conclusion The use of high-resolution thin-layer CT in the early diagnosis of lung adenocarcinoma can clearly see the characteristics of the tumor and the internal structure of the lesion area， improve the imaging quality of CT， and improve the diagnosis rate.
