MR imaging provides excellent spatial resolution and
anatomical soft tissue contrast, yet there are still
limitations in detecting and delineating early-stage
cancer lesions when they are curable. In hopes of
extending ideas for a multiparametric, quantitative MRI
data set, we evaluated a unique approach for MR contrast
by utilizing the thermal responses of heat-sensitive MR
parameters. We look for the accuracy and repeatability
in measuring these parameters, and evaluate if
heat-induced contrast mechanisms have the potential to
add information to conventional MR imaging contrast
types for better identification and characterization of
in vivo tumors.
