Facilities for monitoring blood flow during MB-guided diagnostic and therapeutic interventions

In this paper we describe a hardware and software environment for making av ailable quantitative blood now data inside and outside the magnetic resonan ce (MR) scanner room during MR-guided diagnostic and therapeutic interventi ons. The configuration allows for triggered and non-triggered examinations and provides the interventionalist with updated results within 1 second fro m data acquisition. The practicality of the setup and its potential for cli nical and investigative purposes are demonstrated in vitro and in vivo. (C) 1999 Wiley-Liss, Inc.
