SU-E-I-33: Advances in Dose Metrics and Dose Reduction Strategies for Interventional Fluoroscopy

Area of Science:

• Medical Imaging Physics
• Radiological Sciences
• Interventional Radiology

Background:

• Fluoroscopy procedures involve significant radiation exposure risks for both patients and healthcare professionals.
• Traditional dose metrics may not fully capture real-time exposure, necessitating advanced monitoring.

Purpose of the Study:

• To review current dose metrics and dose reduction strategies in fluoroscopy.
• To assess the impact of these advancements on patient and personnel safety during interventional procedures.

Main Methods:

• Exploration of advanced dose metrics like real-time dose mapping and DICOM-based dose calculation.
• Evaluation of dose reduction features including dose/frame rate settings, software options, and shielding.
• Investigation of real-time dose monitoring (e.g., DoseAware) and dose alert systems.
• Analysis of physician practices and implementation of a practice improvement cycle.
• Discussion of physician follow-up for potentially high-dose patients.

Main Results:

• Implementation of reviewed techniques led to reduced patient and personnel radiation doses in interventional settings.
• Recording technical parameters and fluoroscopy dose improved understanding of optimal settings and dose levels.
• Enhanced awareness and adherence to radiation safety protocols.

Conclusions:

• This review serves as a guide for radiological staff to optimize patient and self-protection during fluoroscopy.
• Provides criteria for healthcare providers to implement quality improvements in interventional radiology practices.
• Emphasizes the importance of continuous learning and adaptation of new technologies for radiation safety.
