The radiographic chest screening has been applied within the Belgian Armed Forces since 1938, to detect tuberculosis. In order to evaluate the actual efficiency--and the utility--of this diagnostic method, the authors have made a prospective study of the examinations performed during a period of six months. The patients in whom a radiologic chest examination would have been performed in every case, on the basis of the clinical or anamnestic elements, were ruled out. The efficiency of the examination is defined as the number of decisions of disability for the armed service, divided by the total number of performed chest examinations. We found 72 (24/10,000) cases of disability for a total number of 30,572 examinations. We found only 9 (3/10,000) cases of tuberculosis and 3 (1/10,000) cases of malignant lesions. The number of cases of tuberculosis is comparable with the rates found in other European studies. The actual efficiency of the radiographic chest screening is thus very low.
自1938年以来，比利时武装部队一直采用胸部X光筛查来检测肺结核。为了评估这种诊断方法的实际效果和实用性，作者对六个月内进行的检查进行了前瞻性研究。那些根据临床或既往病史本应在每种情况下都进行胸部X光检查的患者被排除在外。检查的效果定义为因服役而判定残疾的人数除以进行的胸部检查总数。在总共30572次检查中，我们发现72例（每10000人中有24例）残疾。我们仅发现9例（每10000人中有3例）肺结核病例和3例（每10000人中有1例）恶性病变病例。肺结核病例数与其他欧洲研究中的发病率相当。因此，胸部X光筛查的实际效果非常低。
