摘　　要：目的 :通过对肺细小支气管纹理的研究 ,探讨对小气道病变的数字化X线摄影 (DR)诊断。方法 :对临床上 92 6例诊断为支气管病变的患者进行了胸部正位DR ,取深吸气憋气法。结果 :发现 2mm左右的小支气管病变10 2例 ,表现为沿支气管树的小支气管管壁增粗 ,出现细轨道征 (10 2例 ,10 90 % ) ,小囊状扩张 ,扭曲 (33例 ,3 5 6 % ) ,支气管走向紊乱 (38例 ,4 10 % ) ,局部区域的小叶性肺气肿 (2 5例 ,2 70 % ) ,小叶性渗出模糊病变 (2 9例 ,3 13% ) ,在经过对症治疗及复查时征象有改善或消失。结论 :使用DR可发现 2mm左右的小支气管改变并能通过计算机的后处理功能进行局部观察 ,发现DR对右下细小支气管的改变较易判断 ,对左侧特别是下部细小支气管的判断由于受到心影的掩盖而受到一定的影响 ,因此 ,DR对细小支气管病变的诊断范畴增宽。Objective: To evaluate the direct digital radiology (DR) diagnosis of the small-airway disease. Methods: A cohort of 926 patients including 534 men and 392 women, clinically diagnosis of bronchial lesion was examined with DR (model Digidelca-C, Nucletron company). The patients inspired maximally and maintained in PA projection.Results: There were 102 patients (10.90%) found bronchial lesions, presented the thickening of the bronchi wall along the tracheobronchial tree (showing 'tram line sign') and 33 patients (3.56%) presented cystic dilation and distortion, 38 patients (4.10%) showed bronchial markings tangle,25 patients (2.70%) had regional centrolobar emphysema, and 29 patients (3.13%) had lobar patchy exudation. The lesion was improved or disappeared after treatment.Conclusion: Using DR can find bronchial lesion (diameter about 2mm) and can observe the regional detail with the help of computer's post-process. In DR image, the right lower lobe lesion was easy to distinguish, whereas the left lower lobe lesion judgment was affected by the hiding of the heart. Hence, comprehending the DR image of small-airway disease greatly widen the range of diagnosis.
