Synopsis

On this study, the impact of temperature and postmortem interval (PMI) on QSM were evaluated for a total of 21 subjects. Temperature and PMI were correlated with values from CSF, white matter (WM) and gray matter (GM). Only the GM presented a significant correlation with both temperature and PMI.
