Patient dose in interventional radiology: a multicentre study of the most frequent procedures in France

In plain language

A French national survey of 4600 interventional radiology procedures found wide variation in patient dose for the same procedure and proposed reference levels for 15 procedures. Staff dose was not measured.

Type of study: Original research, Retrospective cohort study
Who was studied: Patients

Summary based on: the abstract

What it found

National data from 36 departments showed large variability in patient dose for the same procedure.
Key figures: 4600 procedures; 36 departments
Reference levels for cerebral angiography were 90 Gy.cm2 kerma-area product (KAP) and 11 minutes fluoroscopy time.
Key figures: 90 Gm.cm2 and 11 mins
Reference levels for biliary drainage, lower limb arteriography and vertebroplasty were proposed.
Key figures: 35 Gy.cm2/16 min; 75 Gy.cm2/6 min; 70 Gy.cm2/11 min
Proposed French reference levels were lower than most previously published values.
Reference levels should account for procedure complexity and be updated regularly.

Limits to keep in mind

Retrospective survey of patient dose indicators only, with 10 to 30 patients per procedure per centre; no staff dose was measured. Abstract only.
