Improved Luminal Visualization of Flow Diverters after Deployment Using Non-Contrast-Enhanced 3D-TOF-MRA: A Comparison between the Flow-Redirection Endoluminal Device and the Pipeline Flex Embolization Device with Shield Technology

Key Points

• The study aims to enhance luminal visualization of flow diverters through non-contrast-enhanced imaging.
• Compared the effectiveness of non-contrast-enhanced 3D-TOF-MRA for flow diverters.
• Analyzed two devices: the Flow-Redirection Endoluminal Device and the Pipeline Flex Embolization Device with Shield Technology.
• Assessed luminal evaluation accuracy post-deployment of both devices.
• Improved accuracy of luminal visualization using non-contrast 3D-TOF-MRA was observed.
• The Flow-Redirection Endoluminal Device showed significant enhancement in imaging quality.
• The Pipeline Flex Embolization Device also demonstrated improved evaluation but with different performance metrics.
