摘要
目的:探讨肺部孤立性小结节病变的常规CT与高分辨率CT检查与结果。方法:选择笔者所在医院2017年12月-2019年6月收治的120例肺部孤立性小结节病变的患者,随机均分两组,各60例,对照组采用常规CT检查,研究组采用高分辨率CT检查,对比两组检查结果。结果:高分辨率CT检查显示结节内部脂肪成分、结节内点状钙化、血管和支气管穿过的结节均高于常规CT(P<0.05);常规CT检查显示心动伪影0例,低于高分辨率CT 6例(10.00%),差异有统计学意义(P<0.05)。高分辨率CT检查毛刺征、空泡征、毛玻璃样症、血管集束征均高于对照组(P<0.05)。两组病理结果比较差异无统计学意义(P>0.05)。相比病理检查结果,高分辨率CT诊断灵敏度、准确度均高于常规CT(P<0.05)。结论:相比常规CT,高分辨率CT检查成像清晰度、分辨率等进一步提升,对于肺内钙化、脂肪成分、毛刺征、空泡征、毛玻璃样症、血管集束征的显示效果更明显。但鉴于高分辨率CT检查费用昂贵、存在较大辐射等特点,临床上对于常规CT难以明确的结节病灶可以考虑进一步行高分辨率CT检查。
Objective:To investigate the routine CT and high resolution CT examination of solitary small pulmonary nodules and their results.Method:A total of 120 patients with small solitary pulmonary nodules treated in our hospital from December 2017 to June 2019 were randomly divided into two groups,control group (n=60) and study group (n=60).The results of CT and high resolution CT were compared between the two groups.Result:The intra-nodular fat composition,nodular calcification,vascular and bronchial penetrating nodules in high resolution CT were higher than those in conventional CT (P<0.05).Cardiac artifacts in 0 cases were lower than those in 6 cases with high resolution CT (10.00%),the difference was significantly differente (P<0.05).The spiculation sign,vacuole sign,ground glass sign and vascular convergence sign in high resolution CT were higher than those in the control group (P<0.05).There was no significant difference in pathological results between the two groups (P>0.05).Compared with the results of pathological examination,the sensitivity and accuracy of high resolution CT were higher than those of routine CT (P<0.05).Conclusion:Compared with conventional CT,high-resolution CT scans have further improved imaging clarity and resolution,and have more obvious display effects on lung calcification,fat composition,burr sign,vacuole sign,ground glassy disease,and vascular cluster sign.However,in view of the high cost of high-resolution CT examination and the existence of large radiation and other characteristics,clinical nodules that are difficult to be identified by conventional CT can be considered for further high-resolution CT examination.
