Radionuclide Scanning
Disadvantages of Radionuclide Scanning
The amount of radiation exposure from radionuclide scanning depends on which radionuclide is used and how much is used. For example, with a lung scan, the dose is similar to that used in about 100 single-view chest x-rays. Other scans may involve more or less radiation. Radionuclide scanning can take hours to do because of the need to wait between injection and scan to give the radionuclide time to reach the target tissue. Radionuclide scanning images are not as precise as those of X-Rays , Because the Radiation risk during pregnancy , women who are pregnant or may be pregnant should tell their doctor.
