In plain language
At one fenestrated endovascular aneurysm repair (FEVAR) centre, introducing fusion imaging with a team-based radiation safety approach was associated with lower patient skin dose, lower dose-area product (DAP) and shorter procedures. Staff dose was not measured, though lower patient dose generally means less scatter.

What it found
Air kerma (skin dose) was lower after the team-based, fusion-guided approach was introduced.
Key figures: Modern 1.6 Gy (IQR 1.09-2.1) vs Historic 4.4 Gy (3.2-7.05), p<0.001
Dose-area product was lower in the Modern group.
Key figures: 159 Gy.cm2 (IQR 123-226) vs 264.93 Gy.cm2 (173.3-366.8), p=0.006
Procedure time fell substantially in the Modern group.
Key figures: median 285 min (IQR 268-322) vs 450 min (IQR 360-540), p<0.001
Fluoroscopy time and renal function did not differ between groups.
Limits to keep in mind
Small single-centre before-after comparison (21 vs 21 patients) with historic controls; only patient dose metrics were reported, with no staff dosimetry, and structured dose reports such as frame-rate changes were unavailable.
