硅肺融合与硅肺合并结核的X线鉴别诊断是大家感兴趣的问题,也是较困难的问题,现将有关的几点体会,简述于下: 1.支气管影:一般认为明显者可能是结核;但实际意义不大,两者往往均可出现。 2.子灶:子灶是结核的特徵,但要注意是否具备其他结核的特点,如密度,形象等。 3.密度:结核多不均匀可有钙化灶。而硅肺融合的密度一般相对一致,从一系列照片来看,开始呈毛玻璃状,随后中心密度相对增大,直至边缘清楚,成为相当均匀高密度影像。 4.形状及边缘:结核形状多不规则,边缘多不整齐。融合形状较为规则,边缘也较整齐。
Silicosis and silicosis pulmonary tuberculosis X-ray differential diagnosis is an issue of interest to everyone, but also a more difficult issue, the relevant experience is now outlined below: 1. Bronchial shadow: It is generally believed that the obvious may be Tuberculosis; but the practical significance is not big, both can often appear. 2. Foci: Foci are tuberculous features, but pay attention to whether there are other characteristics of tuberculosis, such as density, image and so on. 3. Density: uneven tuberculosis may have calcification. The density of the silicosis fusion is generally relatively consistent, from a series of photos, began to frosted glass, and then the center of the relative increase in density until the edge is clear, a very uniform high-density images. 4. Shape and edge: Tuberculosis more irregular shape, more irregular edges. Convergence shape is more regular, the edge is more neat.
