Interventional Radiology Research Lab

The IR Research Lab is a multi-disciplinary research group whose studies focus on basic, translational and clinical aspects of image-guided therapy. In collaboration with a large number of internal and external academic partners and external industry partners, the IR Lab’s accomplishments included novel endovascular devices, imaging techniques, in vitro and animal models of disease, and industry standard support of multi-center, international clinical device trials. The IR Lab has grown rapidly since its inception; over 100 papers have been published and $4.5 million have been awarded in grant funding from various government and industry sponsors.

Research Directions


Developing a family of novel ChemoFilter devices to remove drugs from the blood; this work has also led to additional sponsored funding as well as formation of a startup company.

Interventional MRI

  • developing tools to perform endovascular stroke treatment under 3T MRI guidance so stroke patients can be treated in any 3T MRI scanner or in a combined X-ray/MRI (XMR) suite
  • designing, prototyping, and testing endovascular devices in vitro and in vivo, the latter at our co-located large animal surgical and imaging facility
  • developing remote controlled endovascular catheter systems and testing them in vitro and in vivo in both the x-ray and 1.5T MRI environments
  • improving sensitivity and safety of endovascular MR imaging at 3T   
  • novel endovascular therapies for stroke, aneurysms, vascular malformations, and tumors of the brain, spine, head and neck
  • translational research on interventional MRI and endovascular therapy, including large animal studies and human studies
  • evaluating treatment of image-guided acute ischemic stroke in patients with wake-up stroke or uncertain time of stroke onset
  • multicenter international clinical trials evaluating of endovascular stents and flow diverters for the treatment of brain aneurysms
  • evaluating endovascular embolectomy devices for stroke treatment
  • evaluation of advanced applications in clinical x-ray angiography
