EFFECTIVE DOSE IN PEDIATRIC INTERVENTIONAL CARDIOLOGY.

The aim of this study was to estimate the effective doses (EDs) to children undergoing pediatric interventional cardiology examinations in hospitals of St.-Petersburg, to calculate associated dose conversion coefficients (DCCs) and to investigate their dependence of different parameters of the various procedures. Basic parameters of pediatric cardiology examinations and patient doses were studied in three main pediatric city hospitals.

Patient doses from medical examinations in Russia: 2009-2015.

The aim of this study was to evaluate adult patient doses in Russia in the context of patient protection. Effective doses from x-ray and nuclear medicine examinations were assessed using two approaches. The first was based on data collection performed by the authors in hospitals in St.

Russian practical guidance on radiological support for justification of X-ray and nuclear medicine examinations.

An important part of the justification process is assessment of the radiation risks caused by exposure of a patient during examination. The authors developed official national methodology both for medical doctors and sanitary inspectors called 'assessment of radiation risks of patients undergoing diagnostic examinations with the use of ionizing radiation'. The document addresses patients of various age groups and a wide spectrum of modern X-ray and nuclear medicine examinations.

Studies of patient doses in interventional radiological examinations.

In Russia, especially in big cities like St. Petersburg, the annual number of interventional radiological (IR) examinations for both diagnostic and treatment purposes is increasing continuously. However, IR examinations might involve high patient doses and even the risk of skin injures that should be prevented.
