title: Potential for optimisation of paediatric chest X-ray examination.
abstract: The purpose of this study was to compare the important aspects of paediatric radiological practice and the patient doses from chest X-ray examinations performed in three hospitals in Bulgaria. Data from 163 paediatric patients were recorded using a standardised form. Entrance surface air kerma (ESAK) to patient was calculated from the air-kerma air product (KAP) and field size measurements. Large variations were found for KAP and ESAK. Inappropriate film size and insufficient collimation were often used. Inappropriate use of automatic exposure control and antiscatter grid was found. In most cases, no attention was paid to reduce dose to sensitive organs by means of shielding or proper collimation. Recommendations were given to the hospitals on how to reduce patient doses in paediatric chest radiography.
