尘肺的诊断,目前国内外仍以常规电压胸片为诊断的主要依据,但该片所显示的平面图上层次结构由于受肋骨影及血管影的重合,造成其分辨率低,尤其是尘肺中1—3mm的小阴影在观察其形态、结构上都不理想。
The diagnosis of pneumoconiosis is still the main basis for the diagnosis of conventional voltage chest X-ray at home and abroad, but the resolution of the hierarchical structure shown on the plan due to the overlap of the shadow of the ribs and the blood vessels results in low resolution, especially pneumoconiosis 1 -3mm small shadow in the observation of its shape, structure is not ideal.
