ICA or VA dissection was defined by clinical and imaging, computed tomography angiography (CTA), MR angiography (MRA), and digital subtraction angiography (DSA) findings. The length of DWI hyperintensity was compared to length of the occlusion or stenosis on the angiographic examination.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>In 28 patients, 30 dissected arteries were analyzed. Time intervals from the onset of the first clinical symptoms to the radiological evaluation ranged from 1.5\u00a0h to 42\u00a0days. In 28 (93%) of the dissections, a high signal intensity of the affected artery was present on DWI. The measurement of the dissection length on DWI compared to DSA showed a mean deviation of 2.7\u00a0mm and a standard deviation of 3.7\u00a0mm.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>DWI is a highly sensitive and valuable pulse sequence for the detection of dissected cervical arteries even in the first hours after symptom onset. In contrast to CTA and MRA, DWI can be a potential tool for a reliable measurement of the dissection length.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00234-021-02842-4","type":"journal-article","created":{"date-parts":[[2021,11,13]],"date-time":"2021-11-13T05:02:58Z","timestamp":1636779778000},"page":"1135-1144","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["The potential role of diffusion weighted imaging in the diagnosis of early carotid and vertebral artery dissection"],"prefix":"10.1007","volume":"64","author":[{"given":"Mohammad","family":"Almohammad","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mete","family":"Dadak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Friedrich","family":"G\u00f6tz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Donnerstag","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anita Blanka","family":"Tryc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nima","family":"Mahmoudi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9298-2897","authenticated-orcid":false,"given":"Mike P.","family":"Wattjes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,11,13]]},"reference":[{"key":"2842_CR1","doi-asserted-by":"publisher","first-page":"898","DOI":"10.1056\/NEJM200103223441206","volume":"344","author":"WI Schievink","year":"2001","unstructured":"Schievink WI (2001) Spontaneous dissection of the carotid and vertebral arteries.
