摘　　要：目的 对比胸部高分辨CT诊断技术与病理检查诊断孤立性肺小结节疾病的结果与应用价值。方法 回顾性分析2021年10月—2023年4月靖江市人民医院收诊治疗的68例孤立性肺小结节患者的临床资料,均接受胸部高分辨CT技术检查,以病理检查结果为金标准,计算胸部高分辨CT诊断的灵敏度、特异性及准确率,同时计算胸部高分辨CT用于诊断良恶性孤立性肺小结节的符合率。对比良恶性孤立性肺小结节CT征象表现。结果 68例孤立性肺小结节患者经病理检查结果显示,恶性结节患者13例,占比19.12%,良性结节患者55例,占比80.88%,通过计算,胸部高分辨CT技术特异性为98.18%、灵敏度为92.31%、准确率为97.06%,Kappa值为0.905。胸部高分辨CT诊断良恶性孤立性肺小结节的符合率均超过80.00%。通过分析CT征象结果显示,恶性结节患者分叶征、毛刺征、空泡征、胸膜凹陷征、血管集束征占比率均高于良性结节患者,差异有统计学意义(P<0.05)。结论 临床诊断孤立性肺小结节疾病可采用胸部高分辨CT技术,与病理检查结果具有较高一致性,能够清晰观察CT征象表现,鉴别良恶性,为临床提供可靠影像支持。Objective To compare the results and application value of chest high resolution CT and pathological examination in the diagnosis of isolated pulmonary nodules.Methods A retrospective analysis was performed on clinical data of sixty-eight patients with isolated pulmonary nodules admitted to Jingjiang People's Hospital from October 2021 to April 2023.All of them were examined by high-resolution CT of the chest,and pathological findings were used as the gold standard.The sensitivity,specificity and accuracy of chest high resolution CT were calculated,and the coincidence rate of chest high resolution CT in the diagnosis of benign and malignant solitary pulmonary nodules was calculated.The CT findings of benign and malignant solitary pulmonary nodules were compared.Results Pathological examination results of 68 patients with isolated pulmonary nodules showed that 13 patients with malignant nodules,accounting for 19.12%,and 55 patients with benign nodules,accounting for 80.88%.Through calculation,the specificity,sensitivity and accuracy of chest high resolution CT were 98.18%,92.31% and 97.06%.The Kappa value was 0.905.The coincidence rate of diagnosis of benign and malignant solitary pulmonary nodules by chest high resolution CT was more than 80.00%.The results of CT showed that the ratio of lobular sign,burr sign,vacuole sign,pleural depression sign and vascular cluster sign in patients with malignant nodules was higher than that in patients with benign nodules,and the difference was statistically significant(P<0.05).ConclusionI n clinical diagnosis of isolated pulmonary nodules,high resolution CT technology can be used,which has a high consistency with pathological examination results,and can clearly observe CT signs and manifestations,distinguish benign and malignant,and provide reliable image support for clinical practice.
