Ultra-high resolution imaging of ischemic stroke. Axial 7 T contrast-enhanced 3D-FLAIR image of 50-year-old female with a recent right-sided ischemic stroke with hemorrhagic transformation, repetition time 8000ms, echo time 300ms, inversion time 2200 ms, acquired voxel size 0.8×0.8×0.8 mm³, reconstructed voxel size 0.5×0.5×0.5 mm³, field-of-view 250x250×190 mm³, scan duration 10:48 min. A hyperintense border is seen to surround the lentiform nucleus (putamen and globus pallidus, arrowheads), which appears hypointense due to blood components. A smaller infarct is also seen in the insular region (black arrow), and multiple hyperintense dots are also seen along the ventricular border of the head of the caudate nucleus (white arrow), all of which are compatible with satellite infarctions.
