Abstract
In a method for spatially resolved temperature monitoring in an examination subject, a suspension of ferromagnetic microparticles is intracorporeally introduced into the body Curie temperature of which substance corresponds to a desired temperature limit value. By means of an MR measurement, a spatially resolved representation of the body is obtained with artifacts that are caused by the substance being in the ferromagnetic state being employed as a criterion for determining that the temperature limit value has not yet been reached.
Claims8
A method for spatially resolved temperature monitoring in a living body, comprising the steps of:
- providing a ferromagnetic substance having a Curie temperature corresponding to a predetermined body temperature limit value;
- intracorporeally introducing said substance into a living body;
- obtaining magnetic resonance data from said living body with said substance intracorporeally introduced therein;
- producing an image of said living body from said magnetic resonance data, said image containing artifacts due to said substance as long as said Curie temperature is not reached;
- and
- determining, from a presence of said artifacts in said image, that said body temperature limit value has not been reached.
