T2*-weighted imaging

T2*-weighted imaging of the brain 26 weeks after subarachnoid hemorrhage, showing hemosiderin deposits as hypointense areas.[1]

T2*-weighted imaging is an MRI sequence to quantify observable or effective T2 (T2* or "T2-star"). In this sequence, hemorrhages and hemosiderin deposits become hypointense.[2]
