目的探讨胸部数字化 X 线断层融合检查(DTS)对肺部占位病变的检出能力.资料与方法对57例有肺部占位病变的患者进行胸部 DTS 和数字化 X 线摄影(DR)检查,以多层螺旋 CT 结果为参照,分析胸部 DTS 和 DR 检查对肺部占位病变的敏感性,同时评估 DTS 对肺部占位病变特征的检出能力.结果57例患者中,CT 确认肺部占位性病灶83个,DR 和 DTS 分别检出其中48个和79个病灶,敏感性分别为57.8%和95.2%.胸部 DTS 对肺内占位病变的边缘结构和内部特征显示优于 DR.结论 DTS 对肺部占位病变的检出能力接近 CT,敏感性高于 DR,可作为肺内占位病变高危人群筛检和随访的常规手段.

Purpose To evaluate the detection of pulmonary space-occupying lesion using chest digital tomosynthesis (DTS). Materials and Methods Fifty-seven patients with pulmonary space-occupying lesion underwent chest digital radiography (DR), DTS and multidetector CT (MSCT) scan. The detection ability of MSCT served as standard for reference. The sensitivities of chest DR and DTS for detection in pulmonary space-occupying lesion were calculated. Results A total of 83 pulmonary space-occupying lesions were found in 57 patients, including 48 found with DR and 79 found with DTS. The sensitivity for detecting pulmonary space-occupying lesions with DR and DTS were 57.8% and 95.2%, respectively. Chest DTS was superior to DR in manifesting marginal structures and internal characteristics of pulmonary space-occupying lesions. Conclusion Chest DTS is useful in detecting pulmonary space-occupying lesion, and it is the most feasible conventional techniques to detect and follow-up pulmonary space-occupying lesion.
