Guidance Levels in the Nordic Countries: A Preliminary Report for Selected Interventional Procedures

Abstract
The Nordic radiation protection authorities have already published recommended guidance levels for patient doses for six conventional radiological examinations. Over the past two years a similar protocol has been in progress for three interventional procedures. Measurements have been performed in 22 different hospitals in the Nordic countries on patients in the weight range 40-100 kg. The selected procedures are percutaneous transluminal coronary angioplasty (PTCA), percutaneous transluminal angioplasty (PTA) and endoscopic retrograde cholangio- and pancreatio-graphy (ERCP). A total of 281 PTCA procedures, 304 PTA procedures and 147 ERCP procedures are included in the study. The results from this survey are presented as a first attempt to set guidance levels.
