  • Title: [Estimation of radiation exposure in interventional neuroradiology of the head in children compared to exposure of adult patients].
    Author: Hentschel F, Habermaas I, Bien S, Seeger W.
    Journal: Rofo; 1996 Aug; 165(2):176-80. PubMed ID: 8924671.
    Abstract:
    PURPOSE: We reviewed different dosimetric results in three children investigated for haemangioma, arteriovenous malformation, and angioma of the head in comparison to global results in 11 adults. METHOD: The detailed patient dosimetry was performed using thermoluminescence dosimetry (TLD), area-dose exposure meter (ADE), and Alderson phantom. RESULTS: The patient doses of relevant organs ranged in the milli-Grays (mGy) level. The irradiation-induced risk is on a per mil level in respect of ICRP-60. The risk of cerebral angiographic procedures, radiotherapy, or surgical interventions is on a per cent level. The organ doses for staff are on a micro-Gray (microGy) scale and are higher in examination of children than of adults. A statistical limit of examinations depends on yearly or life-time dose limits with regard to the "Röntgenverordnung" (Germany).
