The purpose of this study was to investigate the variation of cerebral temperature and T1 and T2 values by varying the temperature of the formalin-fixed brain, assuming various temperatures during postmortem MRI. It was suggested that the midpoint of the correlation time was around 20℃.
Contrast variation with temperature for T1 and T2WI.
Contrast ratio at different temperatures in T1WI and T2WI
