Retrospective analysis establishes local diagnostic reference levels for low-dose embolization, suggesting it improves patient safety.

The aim is to optimize neurointerventional practices and minimize radiation exposure during coil-only aneurysm treatment.
Conducted retrospective analysis on 245 coil-only procedures
Collected data on dose-area product, reference air kerma, fluoroscopy time, and DSA frames
Calculated local diagnostic reference levels and compared with literature values
P75 values for DAP was 22.4 Gy·cm2, which is lower than the literature range
P75 for Ka,r was 268 mGy, significantly lower than published ranges
Fluoroscopy time averaged 18 min 56 s with 285 DSA frames for P75
P50 values were also lower than literature norms

Sowa et al. (2026) studied this question.
