In plain language
In 212 coronary procedures by one operator team, dedicated cardiac angiography systems delivered 18% to 22% lower patient dose-area product than general-purpose systems, mainly from acquisition. Staff dose was not measured, though lower patient dose generally means less scatter.

What it found
In percutaneous coronary intervention (PCI), total dose-area product (DAP) was 22.1% lower with the dedicated cardiac system than with the general-purpose system.
Key figures: 3280 vs. 4210 μGy·m2, p < 0.001
In diagnostic angiography, total DAP was 18.3% lower with the dedicated cardiac system.
Key figures: 1850 vs. 2260 μGy·m2, p = 0.004
Acquisition DAP drove the difference; fluoroscopy DAP and fluoroscopy time did not differ significantly.
System type was an independent predictor of total DAP on multivariable regression.
Key figures: β = -0.28, p = 0.002
Estimated magnification mode usage was lower with the cardiac system.
Limits to keep in mind
Retrospective single-team study with non-random allocation by room availability; only patient dose metrics measured, staff dose not assessed; magnification usage was estimated.
