Type of neuroimaging
T2*-weighted imaging of the brain 26 weeks after subarachnoid hemorrhage, showing hemosiderin deposits as hypointense areas.[ 1]
T 2 *-weighted imaging is an MRI sequence to quantify observable or effective T 2 (T2* or "T2-star "). In this sequence, hemorrhages and hemosiderin deposits become hypointense.[ 2]
