摘要
目的:探讨对肺部感染患者行低剂量CT扫描检查的价值。方法:收集2023年8月至2024年8月于锦州医科大学附属第三医院进行肺部感染治疗的118例患者作为研究对象。按照检查先后顺序分成参比组(行常规剂量CT扫描)、观察组(行低剂量CT扫描),每组各59例。比较两组的图像质量、辐射剂量等。结果:两组图像信噪比(SNR)、对比噪声比(CNR)相比,观察组比参比组更低(P<0.05)。两组背景噪声评分、整体图像质量评分相比,差异不显著(P>0.05)。两组容积CT计量指数(CTDIvol)、剂量长度乘积(DLP)、有效剂量(ED)相比,观察组比参比组更低(P<0.05)。结论:经低剂量CT扫描检查肺部感染的图像质量与常规剂量CT扫描检查无显著差异,其辐射性更小,安全性更高。
Objective:To investigate the value of low-dose CT scanning in patients with pulmonary infections.Methods:A total of 118 patients treated for pulmonary infections at The Third Affiliated Hospital of Jinzhou Medical University from August 2023 to August 2024 were enrolled as subjects.They were divided into a control group(conventional-dose CT scanning)and an observation group(low-dose CT scanning)based on the order of examination,with 59 cases in each group.The image quality and radiation dose were compared between the two groups.Results:The signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the observation group were significantly lower than those of the control group(P<0.05).No significant differences were observed in background noise scores or overall image quality scores between the two groups(P>0.05).The volume CT dose index(CTDIvol),dose-length product(DLP),and effective dose(ED)in the observation group were significantly lower than those in the control group(P<0.05).Conclusion:Compared with conventional-dose CT scanning,low-dose CT scanning for pulmonary infections demonstrates comparable image quality while significantly reducing radiation exposure,offering higher safety and clinical application value.It is worthy of clinical reference.
