In plain language
In 25 prostatic artery embolization procedures by one interventional radiologist, patient skin doses averaged about 2.4 Gy and the operator's effective dose averaged 17 μSv per case, with higher left-side eye, hand and foot doses.

What it found
Average effective dose to the interventional radiologist per PAE procedure was 17 μSv, despite apron, thyroid collar, ceiling-suspended screen and table curtain.
Key figures: 17 μSv (range, 4-47 μSv)
Operator doses to eyes, hands and feet were all greater on the left side.
Mean total dose-area product per procedure was high.
Key figures: 450.7 Gy·cm2 (range, 248.3-791.73 Gy·cm2)
Digital subtraction angiography accounted for most of the total dose-area product (DAP).
Key figures: 71.5%
Mean patient peak skin dose was about 2.4 Gy, with long fluoroscopy times.
Key figures: 2,420.3 mGy (range, 1,390-3,616 mGy); fluoroscopy time 30.9 min
Limits to keep in mind
Single operator at a single center with only 25 procedures; protective equipment was used but not compared, so its effect cannot be judged. Abstract only.

How this summary was made
ORSIF prepared this summary with AI assistance from the abstract of the paper. A program then checked that the passage supporting each finding appears word for word in that source. A person has not yet reviewed each summary, so read the original before relying on a number. ORSIF summarizes research and does not endorse any product or company. Report a problem with this summary.
