| 摘要 目的：对比高分辨率电子计算机断层扫描（CT）与常规CT检查对肺小结节及早期肺癌的诊断价值。方法：将2018年6月～2020年1月我院收治的肺小结节及早期肺癌患者94例纳入研究。以随机数字表法将其分为观察组及对照组，每组各47例，对照组实施常规CT检查，观察组则实施高分辨率CT检查。比较两组CT肿瘤征象情况（主要包括毛刺征、分叶征、棘突征、钙化征、空泡征、支气管征、胸膜凹陷征、血管集束征），CT扫描图像质量，诊断肺小结节及早期肺癌的效能。结果：观察组各项CT肿瘤征象人数占比均高于对照组（P＜0.05）。观察组CT扫描图像质量优良率为97.87%（46/47），高于对照组的72.34%（34/47）（P＜0.05）。高分辨率CT诊断早期肺癌的灵敏度及准确度、特异度分别为96.67%（29/30）、95.74%（45/47）、94.12%（16/17），高于常规CT检查的74.19%（23/31）、74.47%（35/47）、75.00%（12/16）。结论：高分辨率CT检查对肺小结节及早期肺癌诊断价值显著高于常规CT检查，可作为临床肺小结节及早期肺癌诊断的有效影像学手段，值得临床应用。 |

| ABSTRACT Objective: To study and analyze the diagnostic value of high resolution CT and routine CT in small pulmonary nodules and early lung cancer. Methods: From June 2018 to January 2020, 94 patients with small pulmonary nodules and early lung cancer who were admitted to our hospital were included in the study. They were divided into observation group and control group by random number table method, 47cases in each group. The control group received routine CT examination, while the observation group received high resolution CT examination. The CT tumor signs of the two groups (mainly including burr sign, lobulation sign, spinous process sign, calcification sign, vacuolar sign, bronchogram sign, pleural depression sign, vascular cluster sign), CT scan image quality, and the efficacy of diagnosing small pulmonary nodules and early lung cancer were compared. Results: The proportion of all CT tumor signs in the observation group was higher than that in the control group (P < 0.05). The rate of excellent and good CT images in the observation group was 97.87% (46/47), which was higher than 72.34% (34/47) in the control group (P < 0.05). The sensitivity, accuracy and specificity of high resolution CT in the diagnosis of early lung cancer were 96.67% (29/30), 95.74% (45/47), 94.12% (16/17) respectively, which were higher than 74.19% (23/31), 74.47% (35/47), 75.00% (12/16) in routine CT examination. Conclusion: The value of high resolution CT examination in the diagnosis of small pulmonary nodules and early lung cancer is significantly higher than that of routine CT examination. It can be used as an effective imaging method for the diagnosis of small pulmonary nodules and early lung cancer, which is worthy of clinical application. |
