Retrospective study compares radiation doses in angiographic procedures, indicating increased exposure over a decade.

The aim is to assess changes in radiation doses associated with angiography at Attikon University Hospital over a decade.
Retrospective collection of radiation dose metrics from a newly installed angiographic system and a previous system.
Measured parameters included dose area product (DAP), fluoroscopy-related DAP, patient entrance dose indicators, and fluoroscopy time.
Comparison of these metrics with data from the published literature.
Median DAP values increased by an average of 96.4% over the decade.
Fluoroscopy times remained largely unchanged during the same period.
Current dose levels were lower than values reported in the international literature.

Antonakos et al. (2026) studied this question.
