Imaging services are a vital component of our TOS Center, providing state-of-the-art applications of computed tomography (CT), magnetic resonance imaging (MRI), angiography, and interventional radiology. These services are located within the Mallinckrodt Institute of Radiology at Washington University (http://www.mir.wustl.edu), with facilities located at Barnes-Jewish Hospital (South Medical Campus) and Barnes-Jewish West County Hospital.
Vamsidhar R. Narra, MD, is associate professor of radiology (Abdominal Imaging Section, Division of Diagnostic Radiology), chief of radiology at Barnes-Jewish West County Hospital, and co-chief of Body MRI at Washington University School of Medicine. He is a graduate of Osmania University in Hyderabad, A.P, India (MD, 1990), where he also undertook residency training in diagnostic radiology (1993). Dr. Narra completed an additional residency in diagnostic radiology at Michigan State University in 1997 followed by a fellowship in body MRI at Washington University in St. Louis in 1998, and then remained on the faculty. He has clinical interests and broad experience in all aspects of body MRI, including angiography (MRA), cholangiopancreatography (MRCP), 3D imaging and complex post processing, and computer applications in radiology. Dr. Narra has developed and implemented unique protocols for positional upper extremity MRA in the evaluation of patients with venous TOS, as well as MRA applications for evaluation and follow-up of patients with arterial TOS.
Suresh Vedantham, MD, is professor of radiology (Interventional Radiology Section, Division of Diagnostic Radiology) and associate professor of Surgery at Washington University School of Medicine. He graduated with a BA in biochemistry from Northwestern University (Chicago, IL) in 1988, and an MD from the Pritzker School of Medicine at the University of Chicago in 1992. Dr. Vedantham completed residency training in diagnostic radiology at the University of California, Los Angeles Medical Center (1997) followed by a fellowship in Interventional Radiology at Stanford University Medical Center (1998), before joining the faculty at Washington University in St. Louis. Since that time, he has become widely recognized for expertise in all aspects of venous disease, including deep vein thrombosis (DVT), laser ablation of varicose veins, thrombolysis, mechanical thrombectomy, and application of stents, as well as having substantial experience in treatment of aortic dissection with fenestration and embolization of uterine fibroid tumors. Dr. Vedantham has received numerous awards and is widely published. He is a member of the Technical Advisory Panel for the JCAHO DVT Standards Project, and chairman of the Deep Vein Thrombosis Research Committee Venous Forum, the Varicose Vein Research Committee Venous Forum, and the Research Consensus Panel on Venous Disease of the Society of Interventional Radiology. Dr. Vedantham provides special expertise to our patients with TOS with regard to catheter-based venography, thrombolytic therapy, and pharmaco-mechanical thrombolysis for axillary-subclavian vein thrombosis associated with venous TOS, and applications of interventional radiology (arteriography, balloon angioplasty, endovascular stent placement) for other aspects of TOS.
