Proton resonance frequency-shift based MR temperature imaging was introduced into the rectal temperature measurement in cooling
dead bodies in order to estimate the time of death in legal medicine. A series of MR temperature difference maps in cooling dead rats
could be obtained. Moreover, distribution of cooling rates among pelvic tissues was observed and shown to be related to body
position.

We evaluated 31 ovarian tumors including 8 mucinous tumors by 1H-MR spectroscopy at 3T. High to moderate 2 ppm peaks were
observed in all 8 mucinous tumors, whereas low to slight 2 ppm peaks were observed in 14 of 23 non-mucinous tumors. The 2 ppm
concentration in mucinous tumors (7.39+/-2.85 mM) was significantly higher than that in non-mucinous lesions (3.12+/-1.42 mM)
