Figures
- Fig 1.
MR images of a patient with intracerebral hemorrhage in the left thalamus. T2*-weighted images reveal multiple foci of signal-intensity loss (microbleeds) in the brain stem, thalamus, and cerebral hemispheres.
- Fig 2.
MR images of a patient with recurrent cardioembolic infarction. A, DWI shows hyperintense signal-intensity alterations in the right frontal lobe, indicating acute cerebral infarction. B and C, T2*-weighted images do not show cerebral microbleeds.
