This study was designed to investigate the usefulness of MEMRI for in vivo detection of apoptosis for hypoxic-ischemic newborn rat brain. MEMRI showed high signal intensity regions at 72 hours after injury and Mn2+ administration. The signal intensity of the enhanced regions increased in time upto 1 week. Those enhanced regions in MRI were matched with TUNEL staining for apoptosis. The result of this study suggests that MEMRI can be an tool for in vivo staining of apoptosis.
