Neurointerventional Radiology Procedures

MIR performs more neurointerventional radiology procedures than any other provider in St. Louis and the surrounding areas. We diagnose and treat a variety of conditions that primarily affect the head, neck and spine. Often utilizing catheters and image-guided techniques, most procedures are performed through blood vessels rather than through open surgery.
