In plain language
In one vascular surgeon's 81 endovascular procedures, a mobile C-arm gave higher upper-body doses, especially right neck and shoulder, while the hybrid room with a ceiling screen gave higher lower-body doses. Dosimeter readings, not health outcomes.

What it found
Dose at the lower part of the protective apron was much higher in the hybrid room than with the mobile C-arm.
Key figures: 8.43 mSv vs. 2.74 mSv
With the mobile C-arm, right neck and shoulder doses were higher than left side and higher than in the hybrid room.
Key figures: 1.77 mSv and 1.48 mSv vs. 0.88 mSv and 0.20 mSv
The suspended lead screen in the hybrid room attenuated dose by an estimated 85.6%.
Key figures: 0.18 mSv surgeon side vs 1.25 mSv patient side; 85.6% attenuation
Fluoroscopy time and dose-area product (DAP) did not differ significantly between groups, though DAP per second appeared higher in the hybrid room.
Key figures: 4.5 µGym2/sec vs. 3.1 µGym2/sec
With the C-arm, the chest had the highest dose among body sites.
Key figures: 2.83 mSv
Limits to keep in mind
Single surgeon at a single center, non-randomized sequential groups, with dosimeters worn outside protective equipment; differences in body-site doses were described without statistical testing and room comparison is confounded by screen use.
