This study introduces a new approach using a patient\u2010specific circle of Willis (COW) blood flow model, based on non\u2010invasive quantitative MR angiography (qMRA) measurements, to predict the outcomes of BTO.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We developed individualized COW blood flow models for 43 patients undergoing BTO. These models simulated blood flow and pressure under normal conditions and with the ICA occlusion. We then compared the model's predictions of blood flow changes due to the simulated ICA occlusion to actual qMRA measurements before the BTO.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For all 31 BTO failures, the ipsilateral hemisphere showed an average flow decrease of 15 \u00b1 10% (mean \u00b1 standard deviation), compared to 3 \u00b1 2% in the contralateral hemisphere. In all 12 BTO passes, these figures were 6 \u00b1 3% and 1 \u00b1 0.8%, respectively. Notably, all BTO passes had less than a 10% reduction in the ipsilateral hemisphere. In contrast, 65% of BTO failures and 67% single\u2010photon emission computed tomography (SPECT) failures exhibited a decrease of 10% or more in the same region.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Blood flow reduction exceeding 10% in the ipsilateral hemisphere during BTO is a strong predictor of failure in both BTO and SPECT. Our patient\u2010specific COW blood flow models, incorporating detailed flow and arterial geometry data, offered valuable insights for predicting BTO outcomes. These models are especially beneficial for situations where conducting BTO or SPECT is clinically impractical.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jon.13198","type":"journal-article","created":{"date-parts":[[2024,3,23]],"date-time":"2024-03-23T06:13:35Z","timestamp":1711174415000},"page":"438-444","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A patient\u2010specific circle of Willis blood flow model in predicting outcomes of balloon test occlusion"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3930-5966","authenticated-orcid":false,"given":"Jianmin","family":"Li","sequence":"first","affiliation":[{"name":"Department of Neurosurgery University of Illinois Chicago  Chicago Illinois USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Orthopedics The Ohio State University  Columbus Ohio USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Alaraj","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery University of Illinois Chicago  Chicago Illinois USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinjian","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery University of Illinois Chicago  Chicago Illinois USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kezhou","family":"Wang","sequence":"additional","affiliation":[{"name":"VasSol Inc.
