Radiation exposure to the pediatric patient during cardiac catheterization and angiocardiography. Emphasis on the thyroid gland.

摘要: Thermoluminescent dosimetry was used to measure the radiation exposure skin, thyroid and gonads in 50 consecutive pediatric patients undergoing cardiac catheterization angiocardiography using cine photofluorography. Average exposures were 17.1 R 2.3 0.1 gonads. Fluoroscopy accounted for approximately 80% of skin photofluorography 20-25%. Occasional primary-beam irradiation major contributor gonad exposure. Internal scatter incident x-ray beam primarily responsible exposure, so that infants received relatively high exposures; one receiving 7.3 R. The not frequently primary beam. significance thyroid, particular its relationship carcinoma, are discussed. results compared with other series literature relative serial filming contrasted.
