目的研究与肝硬化相关的周围肺血管的扩张情况及其在CT图像上的影像表现。方法搜集满足条件的112例肝硬化患者组成肝硬化组,60例非肝硬化人员组成对照组,比较两组之间在胸部CT征象上有无统计学差异,比较内容包括:(1)肺血管纹理增粗达胸膜面;(2)双肺小结节影;(3)双肺底层面网格状影;(4)右肺底层面平均密度。征象(1)~(3)为计数资料,出现的记为阳性用1表示,没出现的记为阴性用0表示,征象(4)为计量资料,用CT值记录具体数值,随后采用SPSS 19.0统计软件包进行数据分析,计数资料用χ2检验,计量资料用t检验,检验水准为α=0.05。结果肝硬化组及非肝硬化组之间在上述4项CT征象上比较均有统计学差异,[征象(1):P=0.000,征象(2):P=0.002,征象(3):P=0.002,征象(4):P=0.000,均P<0.05]。结论肝硬化病变可通过某些途径影响肺周围血管,使之扩张,从而表现出不同的胸部CT征象。
Objective To study the expansion of peripheral pulmonary vessels associated with cirrhosis and its imaging manifestations on CT images. Methods A total of 112 patients with cirrhosis and 60 patients with non-cirrhosis were enrolled in the study. The CT findings of the two groups were compared between the two groups. The comparison included: (1) pulmonary vascular Texture thickening up to the pleural surface; (2) small pulmonary nodules; (3) the bottom of the lung mesh-like shadow; (4) the average density of the right lung bottom layer. The signs (1) ~ (3) are the counting data, and the positive ones are indicated by 1, the negative ones are 0, the signs (4) are the measurement data, and the specific values are recorded with the CT value, followed by SPSS 19.0 Statistical software package for data analysis, count data using χ2 test, measurement data using t test, test level of α = 0.05. Results There were significant differences among the four CT signs in the cirrhosis and non-cirrhotic patients. [Signs (1): P = 0.000, Signs (2): P = 0.002, Signs = 0.002, signs (4): P = 0.000, all P <0.05]. Conclusion Cirrhosis of the liver can affect the peripheral blood vessels of the lung by some means to make it expand so as to show different chest CT signs.
