  • Abstract
  • Look Inside

T2* weighted gradient echo image has heightened diagnostic sensitivity to hemorrhage, which is attrib-uted to magnetic susceptibility-induced static field in-homogeneities arising from paramagnetic blood break-down products such as hemosiderin, which shorten T2*. We examined 4 cases of head injury in chronic stage by T2* weighted images and assessed the clini-cal application of this sequence for diagnosis of the in-tracranial lesion. All patients underwent CT scan on acute stage and long-term follow up was performed.
