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).

摘要

目的

我们回顾了3名因头部血管瘤、动静脉畸形和血管痣接受检查的儿童的不同剂量测定结果，并与11名成年人的总体结果进行比较。

方法

使用热释光剂量测定法（TLD）、面积剂量暴露计（ADE）和阿尔德森体模进行详细的患者剂量测定。

结果

相关器官的患者剂量在毫格雷（mGy）水平。就国际放射防护委员会（ICRP）第60号出版物而言，辐射诱发风险处于千分之一水平。脑血管造影程序、放射治疗或手术干预的风险处于百分之一水平。工作人员的器官剂量在微格雷（μGy）范围内，儿童检查中的剂量高于成人。检查的统计限值取决于德国《伦琴射线条例》规定的年度或终身剂量限值。
