In plain language
In 106 patients undergoing liver chemoembolization, a newer-generation angiography system roughly halved patient dose-area product for fluoroscopy and digital subtraction angiography (DSA) while improving image quality. Staff dose was not measured, though lower patient dose usually means less scatter for the fluoroscopy team.

What it found
Fluoroscopy dose-area product was about halved with the second-generation angiography system.
Key figures: 1.4 ± 1.1 vs 2.8 ± 3.4 Gy·cm; P = 0.001
DSA dose-area product was also roughly halved with the newer system.
Key figures: 2.2 ± 1.2 vs 4.7 ± 2.3 Gy·cm; P = 0.003
Image quality scores improved with the newer system for both DSA and fluoroscopy.
Key figures: DSA +30% (P = 0.004); fluoroscopy +76% (P = 0.001)
Reader agreement on image quality was good to excellent.
Key figures: κ = 0.75 and κ = 0.74
Limits to keep in mind
Single-centre-style retrospective comparison of 106 patients with non-randomized groups; only patient dose-area product was measured, so staff exposure reductions are inferred, not shown.
