CT血管征在肺微小结节定性诊断中的价值探讨

The Value of CT Angiography in the Qualitative Diagnosis of Pulmonary Micronodules

目的探讨CT血管征在肺微小结节定性诊断中的价值。方法方便选取该院于2017年11月—2018年11月收治的240例肺微小结节患者进行研究,行CT扫描后根据结节性质分为研究组与对照组,各组人数120例。分别对两组患者行CT扫描,对比两组患者的血管征分型、灵敏度等。结果研究组CT血管阳性分布93例,敏感度为77.50%;对照组CT血管分布阳性为56例,敏感度为46.67%。研究组敏感度高于对照组,差异有统计学意义(χ^2=9.015,P<0.05);研究组中,Ⅰ型40例,Ⅱ型号12例,Ⅲ型31例,Ⅳ型10例;对照组中,I型7例,Ⅱ型27例,Ⅲ型3例,Ⅳ型19例。研究组血管征多处于Ⅰ、Ⅲ型,对照组多处于Ⅱ、Ⅳ型。结论CT血管征对肺微小结节定性诊断中,敏感度高,能够较好地为临床判断肺微小结节良恶性病变提供参考,值得推广。

Objective To investigate the value of CT angiography in the qualitative diagnosis of pulmonary micro-nodules. Methods A total of 240 patients with pulmonary micro-nodules admitted to our hospital from November 2017 to November 2018 were convenient and enrolled. After CT scan, they were divided into study group and control group according to the nature of nodules. The number of each group was 120. CT scans were performed on the two groups of patients, and the vascular sign classification and sensitivity of the two groups were compared. Results In the study group, 93 cases of CT blood vessel positive distribution, the sensitivity was 77.50%;the control group had positive CT blood vessel distribution in 56 cases, and the sensitivity was 46.67%. The sensitivity of the study group was higher than that of the control group, the difference was statistically significant(χ^2=9.015, P<0.05). In the study group, 40 cases were type I, 12 cases were type II, 31 cases were type III, and 10 cases were type IV. In the control group, there were 7 cases of type I, 27 cases of type II, 3 cases of type III, and 19 cases of type IV. The vascular signs of the study group were mostly in type I and III, and the control group was mostly in type II and IV. Conclusion The CT angiography has high sensitivity in the qualitative diagnosis of pulmonary micro-nodules, which can provide a reference for the clinical diagnosis of benign and malignant lesions of pulmonary micro-nodules. It is worthy of promotion.
