摘　　要：目的 研究比较胸部螺旋CT平扫和靶重建技术对肺结节的诊断价值。方法 选取2021年7月—2023年5月新沂市人民医院收治的89例肺结节患者为研究对象,对所有研究对象予以胸部螺旋CT平扫和靶重建技术,收集并分析不同检测方法 的准确度、灵敏度及特异度。结果 CT靶重建技术准确度为97.75%(87/89)、特异度为97.14%(34/35)、灵敏度为98.15%(53/54),高于胸部螺旋CT平扫,差异有统计学意义(χ^(2)=19.264、12.857、7.053,P<0.05);CT靶重建技术影像特征符合率高于胸部螺旋CT平扫,差异有统计学意义(P<0.05)。结论 在针对肺结节良恶性进行诊断时,选择CT靶重建技术进行检查能够进一步提高检测的准确度,能够更准确地检测出病灶影像特征,检测图像清晰度更高。Objective To compare the diagnostic value of chest spiral CT plain scan and target reconstruction in pulmonary nodules.Methods A total of 89 patients with pulmonary nodules in Xinyi People's Hospital from July 2021 to May 2023 were enrolled.Chest spiral CT plain scan and target reconstruction were performed on all subjects,the accuracy,sensitivity and specificity data of different detection were collected and analyzed.Results The accuracy,specificity and sensitivity of CT target reconstruction were higher than those of CT plain scan,and the difference was statistically significant(χ^(2)=19.264,12.857,7.053,P<0.05).The accuracy of CT target reconstruction was 97.75%(87/89),the specificity was 97.14%(34/35)and the sensitivity was 98.15%(53/54).The coincidence rate of CT target reconstruction was higher than that of chest spiral CT plain scan,and the difference was statistically significant(P<0.05).Conclusion In the diagnosis of benign and malignant pulmonary nodules,CT target reconstruction can further improve the accuracy of detection,more accurately detect lesion image features,and improve the resolution of detection images.
