In plain language
In one interventional cardiologist tracked over 1,282 procedures, dosimeters suggested a lead cap lowered measured head dose more than a ceiling shield alone, and the wearer found it comfortable. This is a dosimeter result, not evidence of reduced brain tumour risk.

What it found
Head dose outside the cap without the ceiling shield was much higher than when the ceiling-suspended screen was used.
Key figures: 2.4 to 12.5 times higher
The ceiling shield reduced head dose only partly; a notable head dose remained despite its use.
The authors concluded the lead cap was more effective than the ceiling-suspended screen at reducing head exposure.
The single operator reported the 1,140 g cap as reasonably comfortable for daily use over 18 months.
Key figures: 1,140 grams; 18 months
The ceiling shield also reduced the lower-trunk dosimeter reading outside the apron.
Limits to keep in mind
Single operator at one centre, with non-randomised sequential periods (3 months without and 15 months with the ceiling shield) and quarterly dosimeter readings. Table values are missing from the source, and comfort was self-reported by one person.
