To accurately determine the perfusion territory of a single vessel, super\u2010selective p\u2010CASL is still recommended. <jats:bold>Magn Reson Med 71:2059\u20132070, 2014. \u00a9 2013 Wiley Periodicals, Inc.<\/jats:bold><\/jats:p><\/jats:sec>","DOI":"10.1002\/mrm.24872","type":"journal-article","created":{"date-parts":[[2013,7,22]],"date-time":"2013-07-22T15:13:59Z","timestamp":1374506039000},"page":"2059-2070","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Validation of planning\u2010free vessel\u2010encoded pseudo\u2010continuous arterial spin labeling MR imaging as territorial\u2010ASL strategy by comparison to super\u2010selective p\u2010CASL MRI"],"prefix":"10.1002","volume":"71","author":[{"given":"Nolan S.","family":"Hartkamp","sequence":"first","affiliation":[{"name":"Department of Radiology University Medical Center Utrecht Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Helle","sequence":"additional","affiliation":[{"name":"Philips Technologie GmbH, Innovative Technologies Research Laboratories Hamburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Chappell","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Engineering Department of Engineering Science University of Oxford Oxford UK"},{"name":"Centre for Functional Magnetic Resonance Imaging of the Brain Nuffield Department of Clinical Neurosciences, University of Oxford Oxford UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas W.","family":"Okell","sequence":"additional","affiliation":[{"name":"Centre for Functional Magnetic Resonance Imaging of the Brain Nuffield Department of Clinical Neurosciences, University of Oxford Oxford UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeroen","family":"Hendrikse","sequence":"additional","affiliation":[{"name":"Department of Radiology University Medical Center Utrecht Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reinoud P.
