多层螺旋CT低剂量胸部扫描在肺结节诊断中的应用价值

Investigation on Clinical Value of Low-Dose Multi-Slice Computed Tomography Chest Scan for Diagnosis of Pulmonary Nodules

探讨多层螺旋CT低剂量胸部扫描在肺结节诊断中的应用价值。方法:选取2021年1月—2022年6月仁怀市人民医院收治的肺结节患者52例作为研究对象,均行多层螺旋CT常规剂量胸部扫描和多层螺旋CT低剂量胸部扫描。比较不同剂量多层螺旋CT检查的诊断效能和图像质量。结果:多层螺旋CT低剂量胸部扫描和多层螺旋CT常规剂量胸部扫描诊断肺结节良恶性的敏感度、特异度、准确度比较,差异无统计学意义(P>0.05)。多层螺旋CT低剂量胸部扫描和多层螺旋CT常规剂量胸部扫描图像质量优良率比较,差异无统计学意义(P>0.05)。结论:多层螺旋CT低剂量胸部扫描诊断肺结节敏感度、准确度、特异度较高,可以提供高分辨率的影像,且辐射剂量低,对患者的损伤小,可为患者提供更安全的检查手段,值得临床应用。

Objective:To investigate the clinical value of Low-dose multi-slice spiral computed tomography in the chest in the diagnosis of pulmonary nodules.Methods:52 patients with pulmonary nodules treated in Renhuai People's Hospital from 2021 to January to June 2022 were collected.All patients were examined by both normal-dose multi-slice spiral CT scan and low-dose spiral CT.The diagnostic efficacy and image quality of different doses of multilayer spiral CT were compared.Results:Comparison of the sensitivity,specificity and accuracy of multilayer spiral CT low-dose chest scanning and multilayer spiral CT conventionaldose chest scanning for diagnosing the benign and malignant lung nodules showed no statistically significant difference(P>0.05).Comparison of the image quality between multilayer spiral CT low-dose chest scan and multilayer spiral CT conventional dose chest scan,the difference was not statistically significant(P>0.05).Conclusion:Multilayer spiral CT low-dose chest scan of lung nodules gives sensible,accurate image while the radiation dose is low,and the damage to the patient is small,which can provide a safer approve of examination for the patient,and is worthy of further clinical application.
