A hybrid PRF/T1/T2* sequence is used to measure tissue
temperature and the relaxation parameters T1 and T2* in
real time during MR-guided focused ultrasound (MRgFUS)
heating of in vivo and ex vivo rabbit thigh muscle. T1
and T2* are analyzed as functions of temperature and
thermal dose to investigate whether they are sensitive
to the various processes that occur during the onset and
progression of tissue thermal damage.
