ICH in MRI appearance

T1WI
Hyperacute (intracellular oxy-Hgb): Isointense
Acute (intracelluar deoxy-Hgb): Isointense
Subacute-early (intracellular met-Hgb): Hyperintense
Subacute-late (extracelluar met-Hgb): Hyperintense
Chronic-early (extraelluar met-Hgb & ferritin/hemosiderin wall): Hyperintense
Chronic-late (hemosiderin): Isointense
T2WI
Hyperacute (intracellular oxy-Hgb): Hyperintense with/without hypointense rim
Acute (intracelluar deoxy-Hgb): Hypointense
Subacute-early (intracellular met-Hgb): Hypointense
Subacute-late (extracelluar met-Hgb): HyperHyperintense
Chronic-early (extraelluar met-Hgb & ferritin/hemosiderin wall): Hyperintense with pronounced low signal rim
Chronic-late (hemosiderin): Hypointense
T2*GRE
All hypointense, senseitive to some lesions
DWI
Findings parallel that of convential T2WI
Significant correlation between lesion volume and degree of ADC elevation in perihematoma edema
T1WI with contrast
Ring enhancement appearance in subacute phase
