New research presented in Sydney yesterday (September 2) has found that a new measure of dose may be a more appropriate tool in reducing radiation exposure in children.
The findings were presented at the 63rd Annual Scientific Meeting of the Royal Australian and New Zealand College of Radiology by Dana Jackson and Professor Michael Ditchfield.
Professor Ditchfield – the Head of Paediatric Imaging at Melbourne's Monash Medical Centre – said that the risks associated with radiation exposure are likely to be "ten times greater" in young children compared to adults.
The Size Specific Dose Estimates (SSDE) was pointed out by Ms Jackson and Professor Ditchfield as a more accurate tool for measuring radiation dose. SSDEs take into account the "wide variation" in children's size, enabling a more reliable comparison of dose between institutions and for patients of varying ages and sizes.
Initiatives by various radiology departments and clinics to reduce radiation in children were also outlined, which included the use of breast and thyroid shields, automated exposure control and the use of ultrasound and MRI instead of CT scans.
