MRI ~ 7 days after symptom onset shows early subacute intracranial haemorrhage.
T1w hyperintense (slowly increasing signal intensity representing more Met-Hb, presumably intracellular in intact hypoxic erythrocytes)
T2w center hypointense, surrounding hyperintense perifocal oedema
SWI hypointense (susceptibility representing intracellular Desoxy-Hb and Met-Hb, both paramagnetic)
