In plain language
This review argues that the head and brain of interventional cardiologists and staff can receive substantial cumulative radiation, that evidence on brain cancer and cognitive effects is suggestive but inconclusive, and that head protection and systematic health studies are needed.

What it found
Without protection, lifetime head dose for a busy interventional cardiologist may reach 1 to 3 Sv, corresponding to a brain dose around 500 mSv.
Key figures: 1 to 3 Sv head; ~500 mSv brain
Head organ dose in interventional cardiologists is 10- to 20-fold higher than the dose recorded beneath the apron.
Key figures: 10- to 20-fold
Epidemiologic evidence for brain cancer in fluoroscopists is suggestive but not conclusive; a reported cluster of four brain tumours in interventional cardiologists were all left-sided.
Key figures: 3 gliomas and 1 meningioma, all left-sided
Cataracts may be found in up to half of interventional cardiologists; lead eyeglasses reduced eye dose per coronary angiography from 165 to 37 μSv.
Key figures: up to 50%; 165 μSv vs 37 μSv
Ceiling-suspended screens, lead caps or a radioprotection cabin greatly reduce scatter dose to the head.
Key figures: factor of 2000; >100 μSv to 1 μSv per procedure
Limits to keep in mind
Narrative review without systematic search; brain cancer evidence in fluoroscopists relies on small case-control studies with wide confidence intervals and anecdotal case clusters, and neurocognitive effects are extrapolated largely from animal and high-dose data.
