A comparison approach to explain risks related to x-ray imaging for scoliosis
نویسندگان
چکیده
Methods Starting point of the analysis is the Linear Non Threshold (LNT) assumption for radiation stochastic effect [1]: for effective doses (E) below 100 mSv, the probability of future stochastic damage is linearly related to E. This allows to add E from different sources to calculate a cumulative risk of health detriment. Data coming from literature were gathered to determine the average E delivered during X-ray investigation of scoliosis. Subsequently, the major natural sources of radiation, namely cosmic rays, 40K, 222Rn and other radionuclides, were considered. The average E due to these natural sources was compared with E due to the imaging of the vertebral column.

A comparison approach to explain risks related to X-ray imaging for scoliosis, 2012 SOSORT award winner
BACKGROUND X-ray imaging is frequently used as diagnostic approach for scoliosis in children and adolescents. X-ray procedures are considered as justified only when expected benefits exceed related risks. While benefits are well known to physicians, radiological risk awareness can be vague, impeding an optimal communication with patients' parents and possibly leading to discomfort and anxiety. ...
