No imaging modality with an efficacy comparable to that of DSA has been established. This study was conducted to determine the efficacy of contrast-enhanced delay alternating with nutation for tailored excitation (DANTE) T1\u2013sampling perfection with application-optimized contrasts by using different flip angle evolution (SPACE), a high-resolution vessel wall magnetic resonance imaging technique for evaluating the occlusion status of intracranial aneurysms after FD treatment, with DSA serving as the reference standard.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>This retrospective study included 23 patients with 26 aneurysms who had undergone FD treatment between April 2016 and May 2022. Contrast-enhanced DANTE T1-SPACE and DSA were performed as postoperative follow-up imaging studies at 45 time points, both in the same period. The agreement rates for aneurysm occlusion status in the 45 imaging studies were examined.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Contrast-enhanced DANTE T1-SPACE had a sensitivity and specificity of 96.3% (26\/27) and 83.3% (15\/18), respectively, for detecting aneurysm remnants. Overall, 91.1% (41\/45) of findings detected on contrast-enhanced DANTE T1-SPACE were consistent with those on DSA. The findings detected on contrast-enhanced DANTE T1-SPACE were completely consistent with those of intraaneurysmal residual blood flow identified on DSA or high-resolution cone-beam computed tomography images in 74.1% (20\/27) of the examinations that showed incomplete occlusion on DSA. Furthermore, parent artery status after FD treatment on contrast-enhanced DANTE T1-SPACE was consistent with that observed on DSA in 97.8% (44\/45) of examinations.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Contrast-enhanced DANTE T1-SPACE is a very useful option in the follow-up of aneurysms after FD treatment.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2024.5.jns24174","type":"journal-article","created":{"date-parts":[[2024,8,31]],"date-time":"2024-08-31T01:25:06Z","timestamp":1725067506000},"page":"1-10","source":"Crossref","is-referenced-by-count":4,"title":["Efficacy of high-resolution vessel wall MRI in the postoperative assessment of intracranial aneurysms following flow diversion treatment"],"prefix":"10.3171","author":[{"given":"So","family":"Matsukawa","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Ishii","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasutaka","family":"Fushimi","sequence":"additional","affiliation":[{"name":"Diagnostic Imaging and Nuclear Medicine, Kyoto University Graduate School of Medicine, Faculty of Medicine, Kyoto, Japan;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Grinstead","sequence":"additional","affiliation":[{"name":"Siemens Healthineers, Portland, Oregon; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sinyeob","family":"Ahn","sequence":"additional","affiliation":[{"name":"Siemens Healthineers, San Francisco, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayuki","family":"Kikuchi","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Yamada","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masakazu","family":"Okawa","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukihiro","family":"Yamao","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Abekura","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natsuhi","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirofumi","family":"Tsuji","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryo","family":"Akiyama","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiki","family":"Arakawa","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"AJNR Am J Neuroradiol","first-page":"34","article-title":"The pipeline embolization device for the intracranial treatment of aneurysms trial","volume":"32","author":"Nelson PK","year":"2011","unstructured":"Nelson PK, Lylyk P, Szikora I, Wetzel SG, Wanke I, Fiorella D.
