[Patient dose during interventional neuroradiology procedures: Results from a multi-center study]

Area of Science:

• Radiology
• Medical Physics

Context:

• Interventional neuroradiology procedures involve significant radiation exposure.
• Multicenter studies are crucial for establishing generalizable clinical benchmarks.

Purpose:

• To determine patient radiation doses during interventional neuroradiology procedures.
• To propose reference standards for dose monitoring and optimization.

Summary:

• A retrospective analysis of nine departments reviewed seven diagnostic and therapeutic neuroradiology procedures.
• Dose-area product (DAP), fluoroscopy time, and image counts were recorded, showing 4-7 fold variations.
• Reference standards were proposed for procedures like cerebral angiography and embolization using the 75th percentile method.

Impact:

• Provides clinicians with benchmarks to assess and enhance their interventional neuroradiology practices.
• Aims to improve patient safety by standardizing radiation dose management.
• Facilitates quality improvement initiatives in interventional radiology departments.
