road mapping
Fluoroscopic technique displaying vessel anatomy as reference overlay during interventional procedures.
Full Definition
A fluoroscopic imaging technique that captures and stores a contrast-enhanced image of vascular anatomy, which is then displayed as a transparent overlay on real-time fluoroscopic images during interventional procedures. This road map serves as a navigation guide, allowing operators to advance catheters and guidewires through vessels while maintaining visualization of the anatomical landmarks. The technique reduces contrast use and procedure time by providing continuous anatomical reference. Road mapping is particularly valuable in complex vascular interventions where precise navigation is critical.
Usage
Usage note: Often written as one word 'roadmapping' in procedural contexts.
In Context
- "Road mapping was used to guide the wire through the tortuous iliac artery." — Peripheral intervention report
- "The roadmap image quality degraded due to patient movement during the procedure." — Procedural complication note
