Patient grouping for routine protocols, dosimetry and establishment of diagnostic reference levels in paediatric radiology

  1. Kostova-Lefterova

Abstract.

The present study suggests critera for dividing children into groups, for dosimetry purposes, establishment of diagnostic reference levels (DRLs) and comparison with the existing DRLs, as well as for optimization of routine protocols. Anthropometric data for 255 patients was collected in 3 radiology departments, in order to select a criterion for patient groups for further research of the paediatric radiography practice. Equivalent Patient Diameter (EPD) was calculated based on registered patients weight and height. For dosimetry purposes and comparison with the existing DRLs five age groups were proposed: 0-1 month; 1-12 months; 1-4 years; 5-9 years and 10-15 years. For the purposes of optimization of thorax and abdomen conventional and CT examinations, the children were separated into groups, based on age and weight. For the x-ray examinations in the region of the head, the groups were based on the patient age, as the X-ray attenuation by the skull largely depends on the bone density, which changes with the age.

Key words: PAEDIATRIC RADIOGRAPHY. OPTIMIZATION. DIAGNOSTIC REFERENCE LEVEL. DOSIMETRY
