Do hida scans expose patients to dangerous levels of radiation?
10 doctors weighed in across 3 answers
Small dose: If i recall correctly, the total dose of radiation from a hida scan is equivalent to about a year of exposure to the low-level radiation from the environment, so quite low.

Acceptable amount: Tc 99m hida is radioactivity injected intravenously .The liver extracts it from blood stream to show excretion into bile ducts, gall bladder as well as bowel.The amount of irradiation is equal to 3 yr natural background exposure.This isotope is utilized also in children because of relative low irradiation dose and the dose is determined by body weight test should be done if have biliary symptoms.

No: Radiation dose from a standard hida scan (5 mci of radiopharmaceutical administered) is 3.1 millisieverts, equal to just over 1 year of natural background radiation.
