How to find out how much radiation the patient is exposed to during a bone scan when they inject a dye?

5.27 mSv : The common bone scan with 600 mbq of technetium-99m-mdp has an effective dose of approximately 3.5 msv (3, 500 μsv). By the way they do not inject dye, they radioactive material. It is complicated issue. Read more:http://hps.Org/publicinformation/ate/q8077.Html.

4.4 mSv: Depending on the injected dose of the radiopharmaceutical the actual dose to the patient varies. The recommended dose for a whole-body bone scans is generally around 20 mci which gives a radiation dose of 4.4 msv to the patient. To give you a reference, a ct scan of the chest gives a radiation dose of 7 msv and a flight from ny to la gives you a radiation dose of 40 microsv.

Low end of rad, dose: With a bone scan the radiotracer or isotope is injected intravenously and accumulates after a couple of hours in the bones of the skeleton. The common bone scan with 600 mbq of technetium-99m-mdp has an effective dose of approximately 3.5 msv . This is higher radiation than several routine xrays but is thought not to increase cancer risk in adult patient.

Ask the technologist: The technologist at your facility should have recorded the exact dose given and may be able to give you the expected exposure to different body parts. Don't be afraid to ask for this information from the facility where you had the work done.
