Evolution of early perihemorrhagic changes-ischemia vs. edema

T2*-WI and DWI are accurate for the diagnosis of hyperacute ICH. According to serial and crossectional ADC analysis, there is no hint towards the existence of a perihemorrhagic ischemic area that might be saved by early intervention. Future studies should focus on perfusion and metabolic/neurotoxic studies of this particular area and neurotoxic properties of the surrounding edema.
