All participants underwent whole brain delay alternating with nutation for tailored excitation-prepared T1-weighted variable flip angle turbo spin echo (DANTE T1-SPACE) imaging before, immediately after, and 1\u20136\u00a0h after gadolinium injection. Additionally, a phantom experiment was conducted to assess the signal intensity according to T1 values using DANTE T1-SPACE and 3D real inversion recovery sequences.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All five large infarction cases (\u2265\u20095\u00a0cm) had delayed meningeal enhancement on the ipsilateral side, while none of the remaining six small infarction cases (&lt;\u20095\u00a0cm) exhibited delayed meningeal enhancement on MRI. More than half of the entire cases had delayed white matter enhancement adjacent to the infarction. No MMD cases showed delayed enhancement outside postoperative regions. In the phantom experiment, DANTE T1-SPACE (TR\u2009=\u2009700\u20131300 ms) demonstrated stable signal intensity across a T1 range of approximately 500\u20131000 ms. This T1 range corresponds to signal intensity\u2009\u2248\u2009200\u2013600 typically observed in regions showing delayed enhancement in clinical stroke and MMD cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Delayed meningeal enhancement observed in patients with large cerebral infarctions likely reflects alterations in brain clearance pathways. The absence of such enhancement in MMD supports that these enhancements are not attributable to collateral circulation.
