In plain language
In one cath lab, adding a mobile leaded shield during radial diagnostic coronary angiography cut two cardiologists' measured eye dose by about a third to 43% and hand dose by 61-83%, without lengthening procedures. The study was very small.

What it found
Adding a mobile leaded shield reduced operator eye dose in both operators.
Key figures: 43% and 33% reduction (Operators 1 and 2)
The mobile shield reduced operator hand dose substantially.
Key figures: 61% and 83% reduction (Operators 1 and 2)
Chest dose under the apron was below the minimum measurable dose for both operators.
Key figures: <0.01 mSv
Using the shield did not change procedure duration, fluoroscopy time or contrast dose.
Nearly all procedures were done by radial access.
Key figures: 99%
Limits to keep in mind
Only two operators in a single cath lab over two months, with a before-after (non-randomised) design; number of procedures not reported in the abstract and results are dosimeter readings, not health outcomes.
