Some indicative parameters on diagnostic radiology in Spain: first dose estimations

Area of Science:

• Medical Physics
• Radiology
• Radiation Protection

Background:

• A European Community project coordinated by the Complutense University of Madrid focuses on optimizing radiation protection in diagnostic radiology.
• The project aims to collect comprehensive data for accurate patient dosimetry across various examinations.

Purpose of the Study:

• To analyze patient dosimetry data for diagnostic radiology examinations.
• To estimate radiation doses and extrapolate findings to the Spanish population.
• To provide data on examination frequency, room utilization, organ doses, and effective dose-equivalent.

Main Methods:

• Data analysis from the National Institute of Health (NIH) covering 96% of the Spanish population.
• Inclusion of findings from Madrid's hospitals, outpatient centers, and private clinics.
• Extrapolation of dose estimations to the entire Spanish population.

Main Results:

• First estimations of annual examination frequencies and their variation from 1985-1986.
• Calculations of diagnostic room utilization based on annual examination volume.
• Presentation of organ doses, effective dose-equivalent, genetically significant dose, and collective dose for various examinations.

Conclusions:

• The project has successfully performed initial dose estimations for diagnostic radiology in Spain.
• The findings provide a foundation for optimizing radiation protection strategies.
• Further data collection and analysis will refine these estimations and inform public health policies.
