Division of Neuroradiology & Neurointerventional Radiology

Delivering excellence in neuroimaging with a focus on patient care, education, research, and global health leadership

The mission of the U-M Medical School Department of Radiology, Division of Neuroradiology & Neurointerventional Radiology, is to provide exceptional patient care through accessible and dependable clinical services, serve as a center of excellence in education, community service, research, and technology, and advance healthcare through leadership locally, nationally, and globally.

Clinical Care

The division consists of a remarkable team of neuroradiologists and neurointerventionalists. The division is responsible for all neuroimaging performed at the main University Hospital, Mott Children's Hospital, UH satellite clinics and the Ann Arbor Veteran's Administration Hospital. The faculty is a mix of senior, mid-level and junior members.

Neurointerventional Radiology

The multidisciplinary division of Neurointervention consists of physicians and providers from Neurointerventional Radiology (NIR) and Neurovascular Surgery who together are dedicated to the diagnosis and treatment of the entire scope of neurovascular pathology. The Neurointerventional team works in close collaboration with both Adult and Pediatric Neurointensive Care, Stroke Neurology, Emergency Medicine, Otorhinolaryngology, Ophthalmology, and Hematology-Oncology. 

In the common pursuit of neurovascular wellness for our patients, the Neurointerventional team is an integral part of the Comprehensive Stroke Center, Spine Oncology Program, Vascular Anomalies Program, and Retinoblastoma Program, among others at Michigan Medicine. Together, we treat and manage diseases of the brain and spinal cord, their bony coverings, and pathologies of the head, neck, face, and orbit, including vascular malformations in both the adult and pediatric populations. We are supported by an excellent and equally dedicated team of NIR Nurse Practitioners, NIR technologists, and nurses.

Education

The division has an ACGME accredited Neuroradiology fellowship program and is accredited for six fellows per year.

Neurotinterventional Radiology

All NIR providers are proud to be certified through ABNS-, ABPN-, and ABR-supervised Recognition of Focused Practice (RFP) in CNS Endovascular Surgery (CNS-ES). One of our providers is also certified by the European Board of Neurointervention (EBNI). The Neurointerventional Fellowship offered as part of our combined curriculum is also CAST/RFP CNS-ES certified. 

Our Fellowship curriculum provides a comprehensive experience encompassing the full spectrum of Neurointervention in both adults and children.

Research

Research is a major emphasis of our division, and all faculty and fellows are involved in ongoing research projects.

The research is supported by the modern, well-equipped facilities at U-M Health hospitals. This includes a dedicated 3T Philips Acieva, which is sited within the hospital and fully administered by the Department of Radiology and a global CT research agreement with GE. Ample support resources are also available to interested faculty through the Associate Chair for Research.

The research interests cover all areas of neuroradiology including brain, spine and head and neck. Specific interests include neuro-oncology, pediatric malformations, psychiatric disorders, autoimmune disorders, multiple sclerosis and fibromyalgia. Because of our tandem clinical and research 3T units, there is a strong emphasis on advanced metabolic and physiologic modalities in the CNS which include diffusion, diffusion tensor imaging, CT and MR perfusion (stroke and tumor imaging), and fMRI in a variety of clinical disorders. 

There is also a strong emphasis on investigating emerging metabolic and physiologic imaging techniques to evaluate head and neck cancer and to differentiate recurrent tumors from post-therapeutic changes in previously treated patients. These technologies include PET-CT, Thallium-201, magnetic resonance spectroscopy, MR perfusion and CT perfusion. Most recently, we have been investigating metabolic and molecular imaging of head and neck neoplasms at 3T.

Faculty members are principle investigators or co-investigators on numerous externally funded grants and clinical trials focused on physiologic and metabolic imaging and multi-institutional trials.

Neurotinterventional Radiology

The Neurointerventional group has produced at least 10 peer-reviewed publications per year over the last 15 years. Faculty have two R21s and three R01s funded by the NIH, centered around intracerebral hemorrhage (ICH). We have participated in several multicenter clinical trials (DEFUSE 3, TIMELESS, MISTIE III) and have contributed to the development of Level 1 evidence in the field of Neurointervention. We have a strong research base with close ties to the basic neuroscience section of the Crosby Center at the Biomedical Science Research Building (BSRB), and we also collaborate extensively with the Biomedical Engineering department.
