Interventional Neuroradiology

Experience counts. And we do more interventional neuroradiology procedures than any other group in the region.

Our interventional neuroradiology (INR) program is one of the oldest and busiest INR services in the nation with the most experienced practitioners. It consists of four full-time staff, one nurse coordinator and two endovascular surgical neuroradiology fellows. We perform a large volume of diagnostic cerebral angiography (over 1,000 per year) and interventional procedures (approximately 500 per year). 

Our Team

Akash P. Kansagra, MD, Director of Endovascular Surgical Neuroradiology

Assistant Professor of Radiology & Neurological Surgery

Co-Director, Stroke and Cerebrovascular Center at Barnes-Jewish Hospital


Akash P. Kansagra, MD, is board certified in radiology and neuroradiology and CAST certified in interventional neuroradiology. Kansagra’s clinical interests span the full spectrum of interventional neuroradiology, including diagnosis and treatment of brain aneurysms, dural arteriovenous fistulas, arteriovenous malformations, carotid disease and acute ischemic stroke. He treats patients of all ages.

Kansagra's research interests include technical development of artificial intelligence and large-scale computer simulation to clinical applications in medicine and particularly neurological disease. He has published extensively in areas of clinical outcomes research and procedural quality improvement and leads several research studies at Washington University.



Christopher J. Moran, MD, Professor of Radiology & Neurological Surgery

Christopher J. Moran, MD, helped establish the endovascular surgical neuroradiology program and has participated in the training of over 40 neurointerventionalists over the past 25 years. Moran’s interests in hemorrhagic and ischemic intracranial vascular disease have led him to lecture more than 250 times across the world. He has trained more than 500 physicians in procedures to treat intracranial aneurysms with coils, stents and liquid materials.

Moran is especially adept with the Pipeline Embolization Device, which has revolutionized the treatment of impossible aneurysms. He is a consultant for major device manufacturers and has received numerous patents for his devices. Moran has published over 350 peer-reviewed papers, abstracts, and invited chapters on a myriad of topics.


Joshua W. Osbun, MD, Assistant Professor Neurological Surgery & Radiology

Joshua W. Osbun, MD, is a board-certified neurosurgeon and CAST certified interventional neuroradiologist. He currently serves as the Associate Neurosurgery Residency Program Director and Director of the Endovascular Surgery Fellowship Program. Osbun's expertise includes clipping, coiling and flow diversion for brain aneurysms; surgical resection and embolization of brain arteriovenous malformations and dural arteriovenous fistulas; surgical treatment of cavernous malformation, meningioma and moya-moya disease; carotid stenting and carotid endarterectomy for carotid artery stenosis; and mechanical thrombectomy for acute ischemic stroke. 

Osbun's research interests include clinical outcome measures in the surgical, endovascular and medical treatment of cerebrovascular disease, new device development and evaluation for use in interventional neuroangiography techniques, and transradial access techniques for neurointervention.



Arindam R. Chatterjee, MD, Assistant Professor of Radiology & Neurological Surgery

Arindam R. Chatterjee, MD, is an attending interventional neuroradiologist specializing in treating stroke, brain aneurysms, brain arteriovenous malformations, brain and spinal dural arteriovenous fistulae, carotid artery stenosis, and congenital vascular malformations using minimally invasive, image-guided procedures and the latest technological advancements. He is board-certified by the American Board of Radiology with additional subspecialty certification in neuroradiology.

 Chatterjee has studied neuronal white matter tract integrity in Alzheimer's patients using MR diffusion kurtosis imaging, evaluated amyloid plaque imaging with PET in patient mild cognitive impairment, and the role of stem cells in the progression of metastatic disease in patients with glioblastoma. Using experience from his NIH-funded research, he also helped develop a mouse model for medulloblastoma at St. Jude Children’s Research Hospital. More recently, Chatterjee has focused on utilizing advances in brain and cerebrovascular imaging technology with minimally invasive treatments for patients suffering from neurovascular disease.
