The follow-up DSA after 6\u20138 months showed that the degree of stenosis was 40% (range, 30\u201372%), and ISR occurred in 4 of 15 (26.7%) lesions. The degree of stenosis assessed using the 3D T1-SPACE imaging technique was 35% (range, 30\u201375%). All four patients with ISR demonstrated significant enhancement. The Pearson correlation coefficient between the two methods was 0.959 (p &amp;lt; 0.05), and the Bland\u2013Altman plot showed that all data points were within the consistency limits (x- \u00b1 1.96 s).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>As a non-invasive imaging modality, 3D T1-SPACE showed great consistency with DSA in measuring the degree of stenosis after intracranial stenting.
