以计算机断层扫描 (CT) 作为参考，比较数字断层合成 (DTS) 和胸部 X 线摄影用于检测气道异常的诊断性能。我们评估了来自 149 名患者（91 名有气道异常和 70 名无气道异常）的 161 个数据集，这些患者接受了 X 线摄影、DTS 和 CT 来检测气道问题。通过评估 X 光片和 DTS 来定位气道异常的严重程度并对其进行评分，并使用 CT 作为参考对图像质量进行评分。采用受试者工作特征（ROC）、麦克尼马尔检验、加权kappa和配对t检验进行统计分析。DTS检测气道病变的敏感性（读者1，93.51％；读者2，94.29％）高于胸片（68.83％；71.43％）。 DTS 的诊断准确率（90.91 %；94.70 %）也显着优于 X 线摄影（78.03 %；82.58 %，均 p < 0.05）。在两个读取器的结果中，DTS 图像质量均明显优于胸部 X 光检查 (1.83, 2.74; p < 0.05)。与放射线照相结果相比，观察者间对 DTS 结果的一致性中等且优越。对于检测容易被纵隔软组织结构掩盖的气道病变，DTS 是一种比放射线照相更准确、更敏感的方式。aEurocent 数字断层合成为气道病变提供了新的诊断选择。aEurocent 数字断层合成比气道病变的放射线照相更敏感和准确。aEurocent 数字断层合成显示出比放射线照相更好的图像质量。aEurocent通过断层合成评估病变严重程度与计算机断层扫描相当。
To compare the diagnostic performance of digital tomosynthesis (DTS) and chest radiography for detecting airway abnormalities, using computed tomography (CT) as a reference.We evaluated 161 data sets from 149 patients (91 with and 70 without airway abnormalities) who had undergone radiography, DTS, and CT to detect airway problems. Radiographs and DTS were evaluated to localize and score the severity of the airway abnormalities, and to score the image quality using CT as a reference. Receiver operating characteristics (ROC), McNemar's test, weighted kappa, and the paired t-test were used for statistical analysis.The sensitivity of DTS was higher (reader 1, 93.51 %; reader 2, 94.29 %) than chest radiography (68.83 %; 71.43 %) in detecting airway lesions. The diagnostic accuracy of DTS (90.91 %; 94.70 %) was also significantly better than that of radiography (78.03 %; 82.58 %, all p < 0.05). DTS image quality was significantly better than chest radiography (1.83, 2.74; p < 0.05) in the results of both readers. The inter-observer agreement with respect to DTS findings was moderate and superior when compared to radiography findings.DTS is a more accurate and sensitive modality than radiography for detecting airway lesions that are easily obscured by soft tissue structures in the mediastinum.aEuro cent Digital tomosynthesis offers new diagnostic options for airway lesions.aEuro cent Digital tomosynthesis is more sensitive and accurate than radiography for airway lesions.aEuro cent Digital tomosynthesis shows better image quality than radiography.aEuro cent Assessment of lesion severity, via tomosynthesis is comparable to computed tomography.
