Title: Absorbed dose in the presence of contrast agents during pediatric cardiac catheterization

Journal Article · · Med. Phys.; (United States)
OSTI ID:6740989

Administration of x-ray contrast agents during heart catheterization examination increases the absorbed radiation dose in tissue. To estimate the dose absorbed by the blood of children undergoing diagnostic heart catheterization and angiocardiography, a number of measurements and calculations were conducted including entrance and exit exposures to the patient. A dose enhancement factor and a mean absorbed dose to the patient's blood were calculated. For eight pediatric patients monitored, absorbed doses to the blood ranged between 3 and 12 rad. These values were two to three times greater than the expected dose without administration of a contrast agent.
