MEDLINE, Embase, Cochrane CENTRAL, Scopus, and Web of Science were searched from inception to April 2025. Two reviewers independently screened studies, extracted 2\u2009\u00d7\u20092 diagnostic data, and assessed the risk of bias using QUADAS\u20102. Pooled sensitivity, specificity, positive and negative likelihood ratios (LR\n                    <jats:sup>+<\/jats:sup>\n                    , LR\n                    <jats:sup>\u2212<\/jats:sup>\n                    ), diagnostic odds ratios (DOR), and area under the hierarchical summary receiver\u2010operating characteristic curve (AUROC) were estimated via bivariate random\u2010effects models. Fifty\u2010two studies (38 TCD; 14 EEG), encompassing 1278 DCI\u2010positive and 3033 DCI\u2010negative assessments, met inclusion. For TCD, pooled sensitivity was 0.79 (95% CI: 0.71\u20130.85) and specificity 0.82 (0.75\u20130.87), with LR\n                    <jats:sup>+<\/jats:sup>\n                    4.3 (3.1\u20136.1), LR\n                    <jats:sup>\u2212<\/jats:sup>\n                    0.26 (0.19\u20130.36), DOR 17 (9\u201331), and AUROC 0.87 (0.84\u20130.90). EEG yielded sensitivity 0.92 (0.83\u20130.97) and specificity 0.70 (0.58\u20130.80), with LR\n                    <jats:sup>+<\/jats:sup>\n                    3.1 (2.1\u20134.6), LR\n                    <jats:sup>\u2212<\/jats:sup>\n                    0.11 (0.05\u20130.27), DOR 27 (9\u201383), and AUROC 0.89 (0.86\u20130.91). Deek's tests showed no publication bias. TCD and EEG both demonstrate strong diagnostic accuracy for DCI after aneurysmal subarachnoid hemorrhage. EEG offers superior sensitivity and rule\u2010out value, while TCD provides balanced rule\u2010in and rule\u2010out performance.\n                  <\/jats:p>","DOI":"10.1002\/jcu.70175","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T05:35:56Z","timestamp":1767850556000},"page":"972-988","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Diagnostic Accuracy of Transcranial Doppler and Electroencephalogram for Delayed Cerebral Ischemia Following Aneurysmal Subarachnoid Hemorrhage: A Systematic Review and Meta\u2010Analysis"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-5184-6881","authenticated-orcid":false,"given":"WenMin","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Neurology Hebei Medical University Third Hospital  Shijiazhuang Hebei Province China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XiaoYun","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Neurology Hebei Medical University Third Hospital  Shijiazhuang Hebei Province China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YaWen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Neurology Hebei Medical University Third Hospital  Shijiazhuang Hebei Province China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,7]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1982.57.6.0769"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12028\u2010023\u201001812\u20103"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00134\u2010022\u201006854\u20103"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2018.06.013"},{"key":"e_1_2_12_6_1","volume-title":"Electroencephalography (EEG): An Introductory Text and Atlas of Normal and Abnormal Findings in Adults, Children, and Infants","author":"Britton J.
