Background/Introduction
Neurointerventional procedures have the potential for greater radiation exposure compared with other radiological procedures.
While the benefits of the procedures outweigh the risks,
patient radiation exposure can cause adverse effects such as radiation burn,
cataracts and malignancy and should be kept as low as possible.
Article 56(1) of the European Union Directive 2013/59/Euratom requires that all member states ensure that radiation doses for interventional procedures are kept as low as reasonably achieveable.
Article 56(2) states that all member states must ensure the establishment,
and use of diagnostic reference levels for radiodiagnostic examinations,
and where appropriate,
interventional radiology procedures[1].
The introduction of dose tracking software in Ireland is a welcome addition to radiology departments to aid in patient dose monitoring.
Dose tracking software allows faster analysis of patient dose,
decreased risk of input error,
and alert to increased dose.
The use of dose monitoring software will aid in analysis of patient dose levels with the end goal of producing accurate national dose reference levels for individual types of neurointerventional procedures (which is currently lacking).
Combining this data with national hospitals performing such procedures will allow for the formation of national dose reference guidelines for these procedures which can be used national as guidelines and as a reference both within the European Union and internationally.
Aim
The aim for this study was to analyse neurointerventional radiation dose levels using dose-tracking software to find determinants of increased radiation dose
Objectives
- Review radiation dose for neurointerventional procedures performed over a one-year period
- Analyse aneurysm coiling procedure variables to determine dose technique relationships
