Dr. Neeraj Chaudhary is a neurointerventionalist by practice. He works under the auspices of the department of radiology and neurosurgery. He has a strong depth in his post graduate training (12 years) including 4 years of general surgery residency (1998 – 2002) and 4 years of Radiology residency (2002 – 2006) in the UK. He moved to the UK after his graduation from medical school in India (University of Calcutta – Kolkata Medical College & Hospital; 1989 – 1997) yearning to get to the source of Medicine (London, England) to get the best training in medicine in the world.
Dr. Chaudhary completed his training in two specialties with UK Board certification in each (Gen Surg – Member of the Royal College of Surgeons MRCS – 2000 & Radiology – Fellow of Royal College of Radiologists FRCR - 2006). His interest in Neurosciences led him to enhance his post graduate training initially in diagnostic neuroradiology (Fellowship – 2006 to 2007 – National Hospital for Neurology & Neurosurgery NHNN, Queen Square, University College London Hospitals NHS Trust) and then 2 years neurointerventional radiology (Fellowship: 2007 to 2008 – NHNN London UK & 2008 – 2009 University of Michigan Health System, Ann Arbor). His training in neurodiagnostic and neurointerventional Radiology was further reinforced by apprenticeship in advanced neuroimaging and neurointerventional procedures in the pediatric population at the Great Ormond Street Children’s Hospital, UK (probably one of the busiest Neurovascular practices in the world) as part of his training at NHNN Queen Square, UK (2006 -2008). He then joined the department of radiology at the University of Michigan as faculty from 2009.
Dr. Chaudhary works in a team of excellent and very talented practitioners across the departments of radiology, neurosurgery and neurology as a neurointerventional radiologist treating patients with neurovascular diseases of the entire neural axis (brain and spinal cord) including head, neck, face and orbit vascular malformations in adults and pediatric age groups. His research interests are in understanding the patho mechanisms of neural injury in hemorrhagic and ischemic stroke. He is involved in both clinical outcomes research and bench side basic science research where he collaborates with the cerebrovascular lab at BSRB with Professors Guohua Xi and Richard Keep.

Dr. Kripfgans’ research focus is centered on clinical implementation and physical aspects of medical ultrasound (diagnostics and therapeutics). As an experimental physicist by training with over 20 years in ultrasound, his expertise ranges from basic science to clinical implementation. The latter involves regular interactions with physician colleagues in Radiology and other departments.
High intensity focused ultrasound (HIFU) is investigated by Dr. Kripfgans (PI) for therapeutic applications in curative and palliative medicine. Together with colleagues from Radiology and Cardiology, myocardial microlesions are generated under ultrasonic and electrocardiographic guidance. Here, ultrasound contrast agents for cardiac imaging are exposed to HIFU to promote the focal treatment of hypertrophic cardiomyopathy by said microlesions. With this method, the clinical operator can non-invasively monitor procedure using real-time ultrasonic imaging, rather than by traditional scaring procedures such as surgical intervention or alcohol ablation. Sonoactive agents are investigated by Dr. Kripfgans for Magnetic Resonance guided thermal ablation procedures such as uterine fibroid ablation or treatment of hepatic cell carcinoma. Together with colleagues from Radiology ultrasound and MRI divisions, the basic science of effective energy conversion from acoustic waves to thermal energy is developed for expeditious procedure times. As a result, HIFU lesions placed by clinical MR guidance are created 15x faster than by current methods. In a collaborative effort of other these and other Radiology and Internal Medicine faculty, these sonoactive agents are engineered to carry infliximab to treat inflammatory bowel disease.
Together with basic scientists and physician scientists from the Departments of Radiology, Internal Medicine, Cardiology, Dentistry, Maternal-Fetal Medicine, and Emergency Medicine, Dr. Kripfgans investigates how quantitative blood volume flow can be assessed avoiding current limitations when acquired in three dimensions. The nature of this approach is straight forward and will revolutionize ultrasonic blood volume flow imaging of the vascular system. As a clinical example, Transjugular Intrahepatic Porto-systemic Shunts are sonographically assessed by basic scientists and Interventional Radiology faculty. This non-invasive and quantitative blood volume flow assessment will potentially set a new industry standard for guiding the treatment of portal hypertension and its sequelae including variceal bleeding and ascites.
Implementation of this quantitative blood volume flow technique on clinical ultrasound scanners is now moving ahead with GE Medical Systems for initial application in Maternal-Fetal Medicine. In a study with OB/Gyn faculty and others, Dr. Kripfgans correctly identified two cases of intrauterine growth restriction and preeclampsia, demonstrating the potential for clinical diagnosis and identification of at-risk pregnancies.
