Recent MR sequences with ultrashort TE (UTE) coupled with respiratory compensation promise to overcome these obstacles. So far, there are very few studies on the relevance of these sequences in children. The aim of the study was to compare the diagnostic value of a respiratory\u2010self\u2010gated three\u2010dimensional UTE sequence versus a conventional respiratory\u2010triggered T2\u2010weighted turbo spin echo (T2\u2010TSE) sequence in a pediatric collective.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Seventy\u2010one patients between 0 and 18 years of age, who were scheduled for a thoracic MRI based on diverse clinical indications, were examined on a 3T MRI system. The UTE and T2\u2010TSE sequences were evaluated by two readers regarding quality features and visualization of eight common pathology patterns.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The image quality of both sequences was equally high, with UTE depicting pleural and central bronchi more clearly. In pathologies, UTE was superior to T2\u2010TSE for so\u2010called \u201cMR\u2010negative pathologies\u201d, significant for air trapping, and in tendency for bullae and cysts. In all remaining pathologies, T2\u2010TSE proved to be at least equivalent to UTE.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>At present, UTE cannot serve as a universal replacement for conventional T2\u2010TSE for all pathologies. It yields, however, a substantial benefit in the context of hyperinflation, emphysema, cysts, or pathologies of the bronchial system.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ppul.25664","type":"journal-article","created":{"date-parts":[[2021,9,7]],"date-time":"2021-09-07T12:59:48Z","timestamp":1631019588000},"page":"3899-3907","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Pediatric MR lung imaging with 3D ultrashort\u2010TE in free breathing: Are we past the conventional T2 sequence?"],"prefix":"10.1002","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7680-0990","authenticated-orcid":false,"given":"Daniel","family":"Gr\u00e4fe","sequence":"first","affiliation":[{"name":"Department of Pediatric Radiology University of Leipzig Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Anders","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology University of Leipzig Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2838-593X","authenticated-orcid":false,"given":"Freerk","family":"Prenzel","sequence":"additional","affiliation":[{"name":"Department of Pediatrics University of Leipzig Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ina","family":"Sorge","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology University of Leipzig Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6080-9993","authenticated-orcid":false,"given":"Christian","family":"Roth","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology University of Leipzig Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Benkert","sequence":"additional","affiliation":[{"name":"MR Application Predevelopment Siemens Healthcare GmbH Erlangen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0960-3740","authenticated-orcid":false,"given":"Franz Wolfgang","family":"Hirsch","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology University of Leipzig Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,9,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-015-3420-y"},{"key":"e_1_2_7_3_1","first-page":"1","article-title":"Pediatric lung MRI: currently available and emerging techniques","author":"Serai SD","year":"2021","journal-title":"Am J Roentgenol"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13244-011-0146-8"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-019-04594-z"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1055\/a-0715-2246"},{"key":"e_1_2_7_7_1","unstructured":"FieldenS MuglerJ MillerW et al.
