The main points of differentiation between cerebral hemorrhage and cerebral infarction on MRI are as follows: 1. In the hyperacute phase, cerebral hemorrhage presents T1 and T2 isosignal on MRI, while cerebral infarction also presents isosignal on T1 and T2, but can present high signal on DWI sequences. 2. In the subacute phase, cerebral hemorrhage shows high signal on T1 and T2, while cerebral infarction remains T1 low signal and T2 high signal.4 In the chronic phase, hematoma turns to low signal on T1 and T2 remains high signal, while the lesion of cerebral infarction softens to form a softening foci with significant prolongation of T1 and T2, forming a signal similar to cerebrospinal fluid. In addition, cerebral hemorrhage generally develops significant occupancy effects with marked edema that can lead to a shift in midline structures, whereas cerebral infarction does not show these manifestations on MRI.
