Applications of magnetic resonance techniques to deep tumor hyperthermia.

Magnetic resonance imaging and spectroscopy have the potential for supporting clinical hyperthermia advances in the treatment of deep tumors. Current spectroscopic techniques can monitor treatment delivery and effectiveness through changes in metabolism and blood flow. Spectra can be obtained in vivo, repetitively and noninvasively; furthermore, current techniques have been implemented to give spatially resolved information. Further advances in MRI/MRS techniques may make it possible to obtained the information necessary for individualized treatment planning, for qualitative monitoring and assessment of treatment results, and for the measurement of thermal fields in vivo.
