This gives a total scan time of 15–20 minutes. The technetium-99m radioisotope is used predominantly in bone and brain scans. For bone scans , the pertechnetate ion is used directly, as it is taken up by osteoblasts attempting to heal a skeletal injury, or (in some cases) as a reaction of these cells to a tumor (either primary or metastatic ...
