1 From the Departments of Radiology (J.S.L., E.M.M., J.L.D., R.W.T.), Oncology (J.S.L.), and Biomedical Engineering (J.L.D.), University Hospitals of Cleveland, Case Western Reserve University, 11100 Euclid Ave, Cleveland, OH 44106, and the Department of Radiology, University of Ulm, Germany (E.M.M.). Received February 25, 1998; revision requested May 4; revision received October 13; accepted November 19. Supported in part by research collaborations with Siemens Medical Systems, Minrad, and Radionics. Also supported in part by grants from the Whitaker Foundation, American Cancer Society, Mary Ann S. Swetland Fund, M.E. and F.J. Callahan Foundation, and the Deutsche Forschungsgemeinschaft grant Me 1593/1-1. Address reprint requests to J.S.L.

Fourteen percutaneous sclerotherapy procedures with magnetic resonance (MR) imaging guidance were performed in three patients with low-flow vascular malformations. All targeted vascular malformation compartments were filled with sclerosing agent without complications in a mean procedural time of 29 minutes. Follow-up imaging demonstrated reduction in size of the treated portions in all patients. In conclusion, sclerotherapy with MR imaging guidance can be performed safely and allows monitoring of injection.
