Image guided interventional procedures
On this page:
The Image Guided Interventional Procedure (IGIP) survey will determine diagnostic reference levels (DRL) for five (5) common interventional and diagnostic angiography fluoroscopic procedures:
- 'Normal’ coronary angiogram
- Cerebral angiogram (1-3 vessels)
- Cerebral angiogram (4+ vessels)
- Abdominal angiogram
- Endoscopic retrograde cholangiopancreatography (ERCP)
The procedure definitions are explained on the survey protocol data sheets. Participants choose which protocols they wish to submit and for statistical accuracy 30 patients per procedure are requested.
To undertake the survey, participants are requested to initially register with ARPANSA. Registered participants will then be sent the Excel survey spreadsheets for completion and email return. Additional copies of the worksheets, for surveying more than one room, may be generated by saving the workbook as a new document.
Each compliant submission will result in a dose report being sent to the participating facility. The report structure will be similar to the MDCT DRL survey report. All submitted data and reports will be strictly confidential between ARPANSA and the facility.
No identifying patient information is required or sought. This means that Human Research Ethics approval is NOT required.
