In plain language
In 279 cardiac device implantations, a system with image noise reduction cut patient dose-area product by 60% overall, mainly in cardiac resynchronization therapy (CRT) procedures; staff dose was not measured, though lower patient dose generally lowers scatter to the fluoroscopy team.

What it found
In CRT implantation, total dose-area product (DAP) was substantially lower with the image noise reduction system than with the conventional C-arm.
Key figures: 1,544 ± 834 cGycm vs 7,252 ± 6,431 cGycm, P < 0.001
Across all device implantation procedures, total DAP fell by 60% with INRT.
Key figures: 60%
In pacemaker/ICD cases, DAP was similar between systems, attributed to pulsed fluoroscopy use on the C-arm and sparse cine.
Key figures: 423 ± 381 cGycm2 vs 417 ± 517 cGycm
CRT reductions came from both lower fluoroscopy DAP and lower cine DAP.
Key figures: 1,414 ± 757 vs 5,854 ± 6,767 cGycm; 130 ± 106 vs 1,399 ± 1,342 cGycm
Patient characteristics and procedure and fluoroscopy times were similar between systems.
Limits to keep in mind
Single-centre, non-randomized before-after comparison of different time periods and different equipment (fixed angiography vs mobile C-arm) with differing fluoroscopy modes; only patient DAP was measured, not staff dose.
