1 From the Departments of Radiology (N.H., T.M., T.O, O.A., S.A., K.O.) and Plastic Surgery (N.K., K.T.), Faculty of Medicine, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-8655, Japan. Received January 14, 2002; revision requested March 5; revision received June 3; accepted July 1. Address correspondence to N.H. (e-mail: naoto-tky@umin.ac.jp).

The feasibility of a method of magnetic resonance (MR)-guided sclerotherapy for hemangioma was evaluated. The distribution of a test injection and a contiguous sclerosant injection was monitored clearly with MR fluoroscopy. Postsclerotherapy T2-weighted MR images depicted areas with and those without effective sclerosant concentration, which enabled performance of selective supplemental sclerotherapy. This method of MR-guided sclerotherapy seems feasible for clinical application.
