Overview
MRA uses time of flight and contrast enhanced techniques to visualize arterial and venous anatomy without ionizing radiation.
Core Sequences
Include time of flight for intracranial vessels and contrast enhanced MRA for extracranial carotid and vertebral arteries.
Perfusion and Flow Quantification
Add phase contrast sequences for flow quantification and dynamic contrast sequences for arteriovenous malformation assessment.
Clinical Use Cases
Useful for stroke workup vascular malformation evaluation and pre surgical vascular mapping.
