Bone three-phase imaging

Bone three-phase imaging can observe bone blood flow and blood pool, and provide more objective indicators for clinical differential diagnosis. (1) Local large blood vessels can be seen 8 to 12 seconds after the blood phase is injected with the imaging agent. The outline of the soft tissue gradually shows that the bone tissue is less radioactive. Corresponding arteries and parts of the two sides have basically the same imaging time. (2) Most of the blood pool phase bone imaging agents remain in the blood, the soft tissue outline is clearer, the radioactive distribution is more uniform, the bone site is slightly sparse, and the sides are basically symmetrical. (3) Each bone in the delayed phase showed the same static and whole body bone imaging.
