关于骨骼疾患的诊断,以往主要依靠X线诊断来显示其形态的变化。在各种骨疾患的初期,骨质的密度变化较少时,用X线诊断具有一定困难。近年来,将放射性核素或标记化合物引入人体,使骨骼显象,不仅能观察到骨骼的形态,而且能获得局部骨骼的代谢功能和血液的供应状况,确定病变的部位,且能早期发现某些骨骼的疾患。 With regard to the diagnosis of skeletal diseases, in the past, X-ray diagnosis was mainly used to show the changes in its morphology. In the early stages of various bone diseases, X-ray diagnosis has certain difficulties when bone density changes less. In recent years, radionuclides or labeled compounds have been introduced into the human body to visualize bones. Not only can the morphology of bones be observed, but also the metabolic function of local bones and the availability of blood can be obtained. The site of lesions can be identified and early detection can be made. Some bone disease.
