Structural and vascular hippocampal and medial temporal lobe imaging at 7T in an older adult. a T2-weighted coronal 7-T MRI scan through the body of the hippocampus, immediately distal to the hippocampal head. Color legend of segmented regions: entorhinal cortex brown, Brodmann area 35 (transentorhinal) teal, Brodmann area 36 dark blue, subiculum mauve, CA1 red, CA2 green, CA3 yellow, dentate gyrus blue. b High-resolution time of flight imaging of hippocampal vascularization allowing to identify supplying vessels from the anterior choroidal artery (solid arrow) and the posterior cerebral artery (dashed arrow). c A structural T1-weighted coronal 7-T MRI in a patient with mild cognitive impairment and markedly enlarged perivascular spaces, particularly in the insular regions (long arrow) but also in the hippocampus (middle arrow). The scan also shows linear perivascular spaces alongside vessels (short arrow). d A microbleed in the anterior temporal lobe (white arrow) in a patient with cerebral amyloid angiopathy imaged with QSM at 7T. e A microbleed with a venous connection, as visualized with a QSM based venography
