摘要：

Purpose The aim of the study was to establish and propose the utilisation of paediatric National Diagnostic Reference Levels (DRLs) for dose length product (DLP) and volume computed tomography dose index (CTDIvol) for most commonly routine computed tomography (CT) for paediatric examinations. Method These were based on the most commonly used routine brain protocol, the chest protocol and the abdominal-Pelvis protocol for head, chest and abdominal scans respectively. 200 images which met the selection criterion were used for the analysis. Results The measured median and 75th percentile CTDIVOL of head were 14.9 and 15.5 mGy, chest was 1.4 and 1.7 mGy, abdomen-pelvis were 5.1 and 15.3 mGy respectively. While DLP for head were 457 and 498 mGy-cm, chest was 13 and 14 mGy-cm, abdomen-pelvis were 26 and 29 mGy-cm. Similar trends were observed in aged 6.-10y and 11-16y. Conclusion The study recommends the use of the established CTDIVOL and DLP as reference values for clinical application in Ghana.
