In plain language
In 164 endovascular cases in a hybrid operating suite, adding dose reduction imaging software lowered patient dose-area product and the primary operator's measured dose, while real-time dose monitoring alone did not significantly change operator dose.

What it found
Primary operator exposure did not change with real-time dose monitoring but fell significantly after dose reduction software was installed.
Key figures: 0.08 ± 0.02 mSv vs 0.03 ± 0.01 mSv; P = .02
Mean dose-area product was significantly lower with dose reduction software than at baseline and than with real-time monitoring.
Key figures: 186,173 ± 16,754 vs 121,536 ± 11,971 mGy/cm2; P = .002 (P1 vs P3); P = .04 (P2 vs P3)
The software had the greatest effect in endovascular aneurysm repair, reducing room dose and primary operator exposure.
Key figures: 0.19 ± 0.04 mSv vs 0.03 ± 0.02 mSv; P < .01
Fluoroscopy time did not differ between phases, suggesting dose changes were not due to shorter procedures.
Limits to keep in mind
Single-centre sequential before-after phases with unequal, small group sizes and no randomization, so case mix and temporal changes may confound results; only abstract available.
