[Estimation of radiation exposure in interventional neuroradiology of the head in children compared to exposure of adult patients].
OBJECTIVE
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.


METHODS
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).
