By using micro\u2010CT scans of in\u2010situ prepared lung casts, tracheobronchial airway morphometry for four strains of mice were obtained: Balb\/c, AJ, C57BL\/6, and Apoe<jats:sup>\u2212\/\u2212<\/jats:sup>. The automated tracheobronchial airway morphometry algorithms for airway length and diameter were successfully verified against previously published manual and automated tracheobronchial airway morphometry data derived from two identical in\u2010situ Balb\/c mouse lung casts. There was also excellent agreement in tracheobronchial airway length and diameter between the automated and manual airway data for the AJ, C57BL\/6, and Apoe<jats:sup>\u2212\/\u2212<\/jats:sup> mice. Differences in branch angle measurements were partially due to the differences in definition between the automated algorithms and manual morphometry techniques. Unlike the manual airway morphometry techniques, the automated algorithms were able to provide a value for inclination to gravity for each airway. Inclusion of an inclination to gravity angle for each airway along with airway length, diameter, and branch angle make the current automated tracheobronchial airway data suitable for use in dosimetry programs that can provide dosimetry estimates for inhaled material. The significant differences in upper tracheobronchial airways between Balb\/c mice and between C57BL\/6 and Apoe<jats:sup>\u2212\/\u2212<\/jats:sup> mice highlight the need for mouse strain\u2010specific aerosol dosimetry estimates.<\/jats:p>","DOI":"10.1002\/ar.24596","type":"journal-article","created":{"date-parts":[[2021,2,7]],"date-time":"2021-02-07T22:56:29Z","timestamp":1612738589000},"page":"2050-2067","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Use of <scp>micro\u2010CT<\/scp> to determine tracheobronchial airway geometries in three strains of mice used in inhalation toxicology as disease models"],"prefix":"10.1002","volume":"304","author":[{"given":"Michael J.","family":"Oldham","sequence":"first","affiliation":[{"name":"Altria Client Services LLC  Richmond Virginia USA"},{"name":"Oldham Associates LLC  Manakin Sabot Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9724-5455","authenticated-orcid":false,"given":"Francesco","family":"Lucci","sequence":"additional","affiliation":[{"name":"Philip Morris International Research and Development  Neuch\u00e2tel Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clement","family":"Foong","sequence":"additional","affiliation":[{"name":"Philip Morris International Research Laboratories Pte.
