The MSV of bilateral thalamus veins, bilateral internal cerebral veins, and bilateral dentate nucleus veins had significant negative correlation with Mini-mental State Examination score; the MSV of bilateral thalamus veins, bilateral dentate nucleus veins, right septal vein had a significant negative correlation with Montreal Cognitive Assessment scores; a significant negative correlation between the MSV of bilateral thalamus veins, left dentate nucleus vein, right septal vein and the Clock Drawing Task score; the MSV of bilateral thalamus veins, left dentate nucleus vein had a significant negative correlation with Activity of Daily Living Scale score. The MSV of left dentate nucleus vein was positively correlated with the course of the disease, the MSV of bilateral septal vein were positively correlated with the total cholesterol, and the MSV of left septal vein had a positive correlation with LDL.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Decreasing cerebral venous oxygen level in AD patients may affect cognitive status, and associated with the deterioration of the disease in AD patients.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnins.2020.570848","type":"journal-article","created":{"date-parts":[[2021,1,18]],"date-time":"2021-01-18T05:38:05Z","timestamp":1610948285000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Correlation Between Cerebral Venous Oxygen Level and Cognitive Status in Patients With Alzheimer\u2019s Disease Using Quantitative Susceptibility Mapping"],"prefix":"10.3389","volume":"14","author":[{"given":"YangYingQiu","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JunYi","family":"Dong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"QingWei","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"WeiWei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BingBing","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ShiYun","family":"Tian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ChunBo","family":"Dong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ZhanHua","family":"Liang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LiZhi","family":"Xie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YanWei","family":"Miao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,1,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"441","DOI":"10.1002\/nbm.717","article-title":"Quantitative measurements of cerebral metabolic rate of oxygen utilization using MRI: a volunteer study.","volume":"14","author":"An","year":"2001","journal-title":"NMR Biomed."},{"key":"B2","doi-asserted-by":"publisher","first-page":"47","DOI":"10.1016\/j.mric.2008.12.002","article-title":"Susceptibility-Weighted Imaging: Clinical Angiographic Applications.","volume":"17","author":"Barnes","year":"2009","journal-title":"Magn.Reson.
