A normal bone scan report usually indicates that there is no abnormal concentration of nuclei in the bone, or no significant abnormal concentration of nuclei in the bone, which are all indicators of a normal report. Because bone scans often use radionuclide CT scans, according to the distribution of radionuclides in the blood to reach the bone, according to the different metabolic activity of the bone and blood circulation levels, and the detection of radionuclide concentrations appear different, so as to understand the metabolism of the bone and blood circulation. A normal report means that there is no concentration where there should not be, which is a normal performance.
