CT血管征在肺微小结节的诊断和鉴别诊断中的价值分析

The Value of CT Vascular Signs in the Diagnosis and Differential Diagnosis of Pulmonary Nodules

目的探究CT血管征对肺微小结节的诊断和鉴别诊断的临床意义。方法将55例受试对象按照肿瘤恶性、良性分为实验组(36例)与对照组(19例)。采用飞利浦16层螺旋CT实施扫描,比较两组结果差异。结果实验组的36例受试对象中,CT血管征阳性28例,阴性8例,灵敏度77.78%;对照组的19例受试对象中,CT血管征阳性8例,阴性11例,灵敏度42.11%,两组间对比,差异具有统计学意义(P<0.05)。实验组CT血管征阳性的28例受试对象中,Ⅰ型7例(19.44%),Ⅱ型5例(13.89%),Ⅲ型5例(13.89%),Ⅳ型11例(30.56%);对照组CT血管征阳性的8例受试对象中,Ⅰ型0例,Ⅱ型2例(10.53%),Ⅲ型0例,Ⅳ型6例(31.58%),差异具有统计学意义(P<0.05)。结论 CT血管征对肺微小结节诊断的灵敏度较高具有定性诊断的意义,CT血管征可指导临床判定肺良恶性病变分型。

Objective To investigate the clinical significance of CT angiography in the diagnosis and differential diagnosis of pulmonary nodules.Methods 55 subjects were divided into experimental group(36 cases)and control group(19 cases)according to malignant and benign tumor.Using Philips 16-slice spiral CT scan,the difference between the two groups was compared.Results Of the 36 subjects in the experimental group,28 cases were positive for CT blood vessels and 8 cases were negative,with a sensitivity of 77.78%.Of the 19 cases in the control group,8 cases were positive for CT blood vessels and 11 cases were negative,with a sensitivity of 42.11%,The difference between the two groups was statistically significant(P<0.05).Among the 28 subjects with positive CT findings in the experimental group,7 cases(19.44%)were typeⅠ,5 cases(13.89%)were typeⅡ,5 cases(13.89%)were typeⅢand 11 cases(30.56%)were typeⅣ.In the control group,8 cases of positive CT angiography showed that there were no case of typeⅠ,2 cases of typeⅡ(10.53%),no case of typeⅢ,6 cases of typeⅣ(31.58%),the difference was statistically significant(P<0.05).Conclusion The high sensitivity of CT angiography in the diagnosis of small pulmonary nodules has the significance of qualitative diagnosis.CT angiography can guide the clinical classification of benign and malignant lung lesions.
