Radionuclide sparing is a relatively normal diagnostic finding on an ECT bone scan, which means that the concentration of radionuclides is low and there may be no lesions. If a high concentration of radionuclides is detected on an ECT bone scan, this indicates a risk of localized lesions, but if radionuclide sparing is detected, this means that the concentration of radionuclides is relatively low and there may be no lesions, which is a normal diagnostic result. However, with only one radionuclide diagnosis, it is not possible to accurately identify the presence of lesions, and it is generally recommended that the patient be followed up regularly for 2 to 3 consecutive tests. If the radionuclides have been sparse and there is no change in the concentration, then it is clear that the problem is not significant, and malignant lesions can be basically excluded. At present, the radionuclide test is sparse, can also be analyzed by pathological examination, if you have symptoms of physical discomfort, you should go to the hospital in a timely manner, consult the physician’s guidance.
