64排CT对孤立性肺结节的临床诊断价值

Clinical Value of 64 Slice CT in the Diagnosis of Solitary Pulmonary Nodules

目的:探讨孤立性肺结节采取64排计算机断层扫描(CT)的临床诊断价值。方法:选取2018年3月至2020年6月大连市甘井子区人民医院收治的150例孤立性肺结节患者,根据病情将恶性结节患者(106例)作为肺腺癌组,良性结节患者(44例)作为良性结节组。比较两组患者CT表现和强化方式的差异性。结果:肺腺癌组患者CT平扫征象中病灶形态、瘤-肺界面、边缘情况及内部成分与良性结节组比较,差异具有统计学意义(P<0.05),两组患者支气管截断征与空洞征无明显差异(P>0.05)。肺腺癌组动脉期轻-中度强化和静脉期延迟强化比例均高于良性结节组,动脉期明显强化、无强化与静脉期强化减退比例明显低于良性结节组,差异具有统计学意义(P<0.05)。结论:对孤立性肺结节采取64排CT检查效果理想,通过特征性表现联合增强特点有助于提高诊断准确性。

Objective To evaluate the clinical value of 64 slice computed tomography(CT)in the diagnosis of solitary pulmonary nodules.Methods 150 patients with solitary pulmonary nodules treated in Ganjingzi District People's Hospital of Dalian from March 2018 to June 2020 were selected.According to the severity of the disease,patients with malignant nodules(106 cases)were regarded as lung adenocarcinoma group and patients with benign nodules(44 cases)were regarded as benign nodules group.The differences of CT manifestations and enhancement methods between the two groups were compared.Results Compared with the benigns nodule group,the lesion morphology,tumor-pulmonary interface,marginal condition and internal components in the CT scan signs of the lung adenocarcinoma group were statistically significant(P<0.05).There was no significant difference in bronchial truncation sign and cavity sign between the two groups(P>0.05).In the lung adenocarcinoma group,the proportions of arterial stage light-to-moderate enhancement and venous stage delayed enhancement were higher than those of the benign nodule group,the arterial stage was significantly enhanced and the venous stage enhancement was significantly lower than that of the benign nodule group(P<0.05).Conclusion 64 slice CT is effective for solitary pulmonary nodules.The combination of characteristic manifestations and enhanced features is helpful to improve the diagnostic accuracy.
