The third ventricle is easily accessible in more than 90% of children and adults using ultrasound (US) via the transtemporal bone-window; thus it can be assessed quickly and free of radiation. In order to use transtemporal US determination of TVD instead of MRI\/CT in clinical practice, it is important to know if there is a correlation and bias between both methods, which is addressed in this study.<\/jats:p><jats:p>\n          Materials and Method\u2003This prospective study investigates 122 children (newborn\u201318 years). Diagnoses encompassed hydrocephalus (50%), tumors (14.8%), and other intracranial pathologies (35.2%). US-based TVD was measured via the transtemporal bone-window using a phased array 1 to 4MHz transducer. Results were compared with TVD measured on simultaneously acquired axial T1-weighted axial MRI or computed tomography (CT) scans.<\/jats:p><jats:p>\n          Results\u2003Overall mean values for TVD were 6.56\u2009\u00b1\u20095.84 and 6.47\u2009\u00b1\u20095.64\u2009mm for US and MRI, respectively. There was an outstanding correlation between TVD measured by MRI and US (r\u2009=\u20090.991, p\u2009&lt;\u20090.01). Bland\u2013Altman analysis showed a mean bias of 0.096\u2009mm with limits of agreement of \u20130.99 and 1.18\u2009mm.<\/jats:p><jats:p>\n          Conclusion\u2003US- and MRI-based TVD measurements correlate excellently and measure almost identical TVD values. US-based TVD is in mean \u223c0.096\u2009mm larger than MRI-based TVD due to a more angulated measurement plane. US is equal to the gold-standard MRI, a fact, opening new avenues for US-based TVD as a first-line assessment tool of ventricular width.<\/jats:p>","DOI":"10.1055\/s-0039-3400978","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T00:23:02Z","timestamp":1575332582000},"page":"185-191","source":"Crossref","is-referenced-by-count":7,"title":["Transtemporal Ultrasound (US) Assessment of Third Ventricle Diameter (TVD): Comparison of US and MRI TVD in Pediatric Patients"],"prefix":"10.1055","volume":"51","author":[{"given":"Susanne R.","family":"Kerscher","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Division of Pediatric Neurosurgery, University Hospital of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louise L.","family":"Schweizer","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Division of Pediatric Neurosurgery, University Hospital of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"N\u00e4gele","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Hospital of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Bevot","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurology and Developmental Medicine, University Children' s Hospital of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Alber","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurology and Developmental Medicine, University Children' s Hospital of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin U.","family":"Schuhmann","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Division of Pediatric Neurosurgery, University Hospital of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,12,2]]},"container-title":["Neuropediatrics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-3400978.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,15]],"date-time":"2020-05-15T22:41:30Z","timestamp":1589582490000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-3400978"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,2]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2020,5,15]]},"published-print":{"date-parts":[[2020,6]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-3400978","relation":{},"ISSN":["0174-304X","1439-1899"],"issn-type":[{"value":"0174-304X","type":"print"},{"value":"1439-1899","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,12,2]]}}}
