Apart from the knowledge about normal perfusion patterns in the preterm and term neonatal brains, the use of ASL sequence provided important additional information in 11 cases (10.8%): increased CBF correlating with electroencephalographic seizure localization in otherwise normal MRI (n = 1), increased CBF in the cortex without clinical information about seizures and with posthaemorrhagic changes (n = 1), increased CBF in the brain stem and decreased in the upper parts of the brain (n = 2), probably reflecting the homeostatic mechanism which allows preferential perfusion of the vital structures of the brain stem, hypoperfusion (n = 1) or hypoperfusion with peripheral hyperperfusion (n = 1) in the area of stroke, hypoperfusion of the posterior areas of the brain in the presence of subarachnoid or epidural haemorrhage (n = 3), significantly increased CBF in the presumed nidus of arteriovenous malformation causing haemorrhage (n = 1), and lack of perfusion in the supratentorial compartment in a\u00a0case of suspected brain death (n = 1).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our short experience but relatively large volume of material encourages the use of ASL in routine neonatal MRI as a\u00a0useful and non-time-consuming tool providing additional important clinical information in a\u00a0significant percentage of cases.<\/jats:p><\/jats:sec>","DOI":"10.5114\/pjr.2021.108165","type":"journal-article","created":{"date-parts":[[2021,9,16]],"date-time":"2021-09-16T09:04:55Z","timestamp":1631783095000},"page":"415-424","source":"Crossref","is-referenced-by-count":2,"title":["Arterial spin labeling in neonatal magnetic resonance imaging \u2013 first experience and new observations"],"prefix":"10.5114","volume":"86","author":[{"given":"Monika","family":"Bekiesi\u0144ska-Figatowska","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylwia","family":"Szkudli\u0144ska-Pawlak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"Kwa\u015bniewicz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnieszka","family":"Duczkowska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Ring","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beata","family":"Iwanowska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Sawicki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3061","published-online":{"date-parts":[[2021,7,10]]},"reference":[{"key":"ref-1148427","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1148\/radiol.2016150789","article-title":"Arterial spin labeling perfusion of the brain: emerging clinical applications","volume":"281","author":"Haller S","year":"2016","unstructured":"Haller S, Zaharchuk G, Thomas DL, et al.
