目的分析CT扫描在肺部病变患 者诊断中的应用价值。方法 回顾性分析 我院收治的74例肺部病变患者的临床资 料，所有患者入院后均已接受CT扫描检查 及穿刺活检，比较CT诊断与病理检查符 合率，分析肺部疾病CT表现特点及诊断 价值。结果 CT检出肺良性病变24例，其 中纤维组织增生11例(91.67%)，肺炎7例 (100.00%)，肺结核5例(100.00%)，非典 型腺瘤样增生2例(50.00%)，1例错构瘤误 诊，1例纤维组织增生、非典型腺瘤样增 生漏诊；CT检出肺恶性病变42例，其中鳞 癌20例(90.91%)，腺癌15例(93.75%)，未 分化癌7例(87.50%)，与病理检查整体符 合度为89.19%。结论 在肺部疾病的诊断 中，采用多层螺旋CT扫描，软组织分辨率 高，无创，重复性好，对肺部良、恶性病 变均有较高的检出率，与病理检查符合度 高，有其较高的临床应用价值。

Objective To analyze the value of CT scan in the diagnosis of patients with pulmonary diseases. Methods The clinical data of 74 patients with pulmonary diseases in our hospital were retrospectively analyzed. All patients underwent CT scan and biopsy after admission. The coincidence rate of CT diagnosis and pathological examination was compared. The CT findings and diagnostic value in pulmonary diseases were analyzed. Results CT detected 24 cases with benign lung lesions, including 11 cases (91.67%) of fibrous tissue hyperplasia, 7 cases (100.00%) of pneumonia, 5 cases (100.00%) of pulmonary tuberculosis, 2 cases (50.00%) of atypical adenomatous hyperplasia. There was 1 case of hamartoma misdiagnosed, 1 case of fibrous tissue hyperplasia and atypical adenomatous hyperplasia missed diagnosed; CT detected 42 cases with lung malignant lesions, including squamous cell carcinomas in 20 cases (90.91%), adenocarcinomas in 15 cases (93.75%) and undifferentiated carcinomas in 7 cases (87.50%). The overall consistency with pathological examination was 89.19%. Conclusion In the diagnosis of pulmonary diseases, the application of multi-slice spiral CT scan is of high resolution to soft tissues, noninvasive, with good reproducibility which has higher detection rate of benign and malignant lung lesions and the high consistency with pathological examination. It is of high clinical application value
