Digital subtraction angiography was the standard of reference.<\/jats:p>\n                  <jats:p>Material and Methods: Fifty consecutive patients with suspected internal carotid artery stenosis underwent CE\u2010MRA and digital subtraction angiography. CE\u2010MRA was performed on a 1.5\u2010T superconducting scanner with the CareBolus technique. CareBolus combines a nearly real\u2010time 2D\u2010FLASH (fast low angle shot) sequence for fluoroscopic triggering and a high\u2010resolution 3D\u2010FLASH with elliptical centric view order for the angiographic pulse sequence (6.0\/2.16\u2009ms [TR\/TE], 30\u00b0 flip angle, 30.98\u2009s acquisition time, 0.88\u2009mm effective (interpolated) partition thickness and a 160\u00d7512 matrix). Intra\u2010arterial digital subtraction angiography and CE\u2010MRA studies were evaluated independently by four blinded readers. Internal carotid artery stenoses were graded according to the NASCET criteria.<\/jats:p>\n                  <jats:p>Results: CE\u2010MRA had an accuracy of 92.53%, a sensitivity of 95.64%, and a specificity of 90.39% for the identification of carotid artery stenoses \u226570% (grade 3). Image quality for suppression of stationary tissue and venous contrast was good, but was reduced in five cases due to patient motion.<\/jats:p>\n                  <jats:p>Conclusion: The CareBolus technique is a useful non\u2010invasive method for high\u2010resolution imaging of the supra\u2010aortic vessels because of its easy application and high sensitivity and specificity. Limitations can occur in non\u2010compliant patients due to motion artifacts during the measurement time.<\/jats:p>","DOI":"10.1080\/02841850410003699","type":"journal-article","created":{"date-parts":[[2004,4,2]],"date-time":"2004-04-02T11:55:26Z","timestamp":1080906926000},"page":"164-170","source":"Crossref","is-referenced-by-count":20,"title":["High\u2010resolution contrast\u2010enhanced magnetic resonance angiography of the carotid arteries using fluoroscopic monitoring of contrast arrival: diagnostic accuracy and interobserver variability"],"prefix":"10.1177","volume":"45","author":[{"given":"B.","family":"Butz","sequence":"first","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U.","family":"Dorenbeck","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Borisch","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Zorger","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Lenhart","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Feuerbach","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Link","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Regensburg Hospital, Regensburg, Germany; Department of Neuroradiology, University of Homburg Hospital, Homburg, Germany; Department of Radiology, Spitalregion St. Gallen, St. Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,8,30]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850410003699","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850410003699","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:46:07Z","timestamp":1777383967000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/02841850410003699"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,4]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2004,4]]}},"alternative-id":["10.1080\/02841850410003699"],"URL":"https:\/\/doi.org\/10.1080\/02841850410003699","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,4]]}}}
