The internal jugular veins (IJVs) are the main venous drainage pathway in supine position. Their patency and geometry should be evaluated under different body inclination angles over a three\u2010dimensional (3D) volume in the healthy situation to better understand pathological cases.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n To investigate whether positional changes in the body can affect the geometrical properties and patency of the venous system.<\/jats:p>\n <\/jats:sec>\n \n Study Type<\/jats:title>\n Prospective.<\/jats:p>\n <\/jats:sec>\n \n Population<\/jats:title>\n 15 healthy volunteers, of which seven males and median age 22\u2009years in a range of 19\u201359.<\/jats:p>\n <\/jats:sec>\n \n Field Strength\/Sequence<\/jats:title>\n A 0.25\u2010T tiltable MRI system was used to scan volunteers in 90\u00b0 (sitting position), 69\u00b0, 45\u00b0, 21\u00b0, and 0\u00b0 (supine position) in the transverse plane with the top at vertebra C2. A gradient echo sequence was used.<\/jats:p>\n <\/jats:sec>\n \n Assessment<\/jats:title>\n Three observers assessed IJVs on patency and created automatic centerlines from which diameter and patency were analysed perpendicular to the vessel at every 4\u2009mm starting at the level of C2.<\/jats:p>\n <\/jats:sec>\n \n Statistical Tests<\/jats:title>\n \n A Student's\n t<\/jats:italic>\n test was used to find statistical difference (\n p<\/jats:italic>\n \u2009<\u20090.05) in average IJV diameters per inclination angle.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The amount of fully collapsed IJVs increased from 33% to 93% (left IJV) and 14% to 80% (right IJV) when increasing the inclination angle from 0\u00b0 to 90\u00b0. In both IJVs, the mean diameter (\u00b1SD) of the open vessels was significantly higher at 0\u00b0 than 90\u00b0 with 6.3\u2009\u00b1\u20090.5\u2009mm vs. 4.4\u2009\u00b1\u20090.1\u2009mm (left IJV) and 6.6\u2009\u00b1\u20090.6\u2009mm vs. 4.3\u2009\u00b1\u20090.4\u2009mm (right IJV).<\/jats:p>\n <\/jats:sec>\n \n Data Conclusion<\/jats:title>\n Tiltable low\u2010field MRI can be used to assess IJV geometry and its associated venous pathways in 3D under multiple inclination angles. Next to a higher amount of collapsed vessels, the average diameter of noncollapsed vessels decreases with increasing inclination angles for both left and right IJVs.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n 2<\/jats:p>\n <\/jats:sec>\n \n Technical Efficacy Stage<\/jats:title>\n 1<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/jmri.28182","type":"journal-article","created":{"date-parts":[[2022,3,24]],"date-time":"2022-03-24T19:18:33Z","timestamp":1648149513000},"page":"1302-1308","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Internal Jugular Vein Geometry Under Multiple Inclination Angles with 3D Low\u2010Field MRI in Healthy Volunteers"],"prefix":"10.1002","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6393-0139","authenticated-orcid":false,"given":"Jordy K.","family":"van Zandwijk","sequence":"first","affiliation":[{"name":"Magnetic Detection & Imaging, TechMed Centre University of Twente Enschede The Netherlands"},{"name":"Department of Vascular Surgery Medisch Spectrum Twente Enschede The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koen M.","family":"Kuijer","sequence":"additional","affiliation":[{"name":"Magnetic Detection & Imaging, TechMed Centre University of Twente Enschede The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chrit M.","family":"Stassen","sequence":"additional","affiliation":[{"name":"Department of Radiology Ziekenhuisgroep Twente Hengelo The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernard","family":"ten Haken","sequence":"additional","affiliation":[{"name":"Magnetic Detection & Imaging, TechMed Centre University of Twente Enschede The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank F.J.","family":"Simonis","sequence":"additional","affiliation":[{"name":"Magnetic Detection & Imaging, TechMed Centre University of Twente Enschede The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,3,24]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.07.096"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.22001"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12987-017-0065-2"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/0268355515586526"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A3557"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2004.070409"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.00291.2017"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.24882"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.00291.2017"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultrasmedbio.2018.04.010"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.23736\/S1824-4777.18.01341-4"},{"key":"e_1_2_5_13_1","unstructured":"AsensioHA SimonisFFJ ten HakenB.
