The efficiency of small-dose digital X-ray study (SDDXRS) of the chest versus film X-ray study (FXRS) and fluorography was studied during prophylactic surveys. SDDXRS competes only with FXRS in evaluating the normal anatomic structures and it compares much favourably with fluography. In chest abnormalities, SDDXRS, unlike FXRS, cannot reveal fine linear shadows, detect bullae in the lung, the upper margin of pleural exudates, changes in the bones worse, but shows soft focal shadows of the decay cavity, abnormal changes behind the shadow of the heart. The efficiency of SDDXRS was superior to fluography in detecting tuberculosis in all points, at the same time SDDXRS virtually have no spoilage that is about 18% at fluography.
在预防性检查中，对胸部小剂量数字X线检查（SDDXRS）与传统X线胸片检查（FXRS）及荧光透视检查的效率进行了研究。在评估正常解剖结构方面，SDDXRS仅与FXRS竞争，且与荧光透视检查相比具有很大优势。在胸部异常情况中，与FXRS不同，SDDXRS无法显示细微的线性阴影，难以检测肺部大疱、胸膜渗出液的上缘，对骨骼变化的显示较差，但能显示坏死腔的软组织局灶性阴影、心脏阴影后方的异常变化。在各方面检测结核病时，SDDXRS的效率均优于荧光透视检查，同时SDDXRS几乎没有损耗，而荧光透视检查的损耗约为18%。
