Devices for interventional MRI must be evaluated for potential radiofrequency induced heating but phantom heating tests can be difficult to relate to intended uses in vivo. We examined in vivo and post-mortem in situ device heating in swine and more realistic phantom in vitro testing of an actively visualized guidewire for interventional cardiovascular MRI.
