This study combined computed tomography (CT) imaging and Rodopas\u2013casting to assess structural and volumetric changes in the lungs of adult male European pond turtles (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Emys orbicularis<\/jats:italic>\n                    <\/jats:styled-content>\n                    ) between extended and flexed postural states of the head, neck, and limbs. Five turtles (550\u2009\u00b1\u200910.22\u2009g) were evaluated under anaesthesia. CT scans quantified lung dimensions, volume, parenchymal thickness, and percentage coelomic occupancy, while Rodopas casts provided detailed bronchial architecture. CT imaging revealed bilateral wedge\u2010shaped lungs positioned dorsally in the coelomic cavity, with the trachea entering from the right side and bifurcating into a longer left and shorter right bronchus. Each lung contained three lateral and four medial secondary bronchi, terminating in sac\u2010like chambers, plus a large caudal terminal chamber. Lateral chambers were larger than medial ones; tertiary bronchi were denser in cranial lung regions. Casting confirmed bronchial branching but showed smaller terminal sac volume than CT, likely due to post\u2010mortem differences. Morphometric analysis showed no significant differences in lung length or height between sides or postures. Cranial lung width decreased significantly in the flexed state (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05), while overall lung volume dropped markedly from 29.93\u2009\u00b1\u20090.33\u2009cm\n                    <jats:sup>3<\/jats:sup>\n                    (left) and 29.77\u2009\u00b1\u20090.33\u2009cm\n                    <jats:sup>3<\/jats:sup>\n                    (right) in extension to 23.41\u2009\u00b1\u20090.33\u2009cm\n                    <jats:sup>3<\/jats:sup>\n                    and 23.31\u2009\u00b1\u20090.32\u2009cm\n                    <jats:sup>3<\/jats:sup>\n                    in flexion (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). Caudal parenchymal thickness was significantly reduced in flexed posture (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05).

Differences between CT and casting highlight the complementary value of both techniques, with CT capturing functional, in\u00a0vivo configurations and casting revealing intricate bronchial anatomy. The data provide new insights into respiratory adaptation and volumetric modulation in semi\u2010aquatic chelonians, with relevance for comparative anatomy, evolutionary biology, and clinical imaging applications.\n                  <\/jats:p>","DOI":"10.1111\/ahe.70125","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T13:20:28Z","timestamp":1779715228000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Combined\n                    <scp>CT<\/scp>\n                    and Rodopas Casting Assessment of Postural Variations in Lung Morphology of European Pond Turtles (\n                    <i>Emys orbicularis<\/i>\n                    )"],"prefix":"10.1111","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4343-4453","authenticated-orcid":false,"given":"Omid","family":"Zehtabvar","sequence":"first","affiliation":[{"name":"Anatomy Sector, Department of Basic Science, Faculty of Veterinary Medicine University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8048-7124","authenticated-orcid":false,"given":"Ali Reza","family":"Vajhi","sequence":"additional","affiliation":[{"name":"Department of Surgery and Radiology, Faculty of Veterinary Medicine University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3276-4649","authenticated-orcid":false,"given":"Hesameddin","family":"Akbarein","sequence":"additional","affiliation":[{"name":"Department of Food Hygiene and Quality Control, Faculty of Veterinary Medicine University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6245-0160","authenticated-orcid":false,"given":"Somaye","family":"Davudypoor","sequence":"additional","affiliation":[{"name":"Veterinary Radiologist, Graduated From Faculty of Veterinary Medicine, University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8940-3620","authenticated-orcid":false,"given":"Seyyed Hossein Modarres","family":"Tonekabony","sequence":"additional","affiliation":[{"name":"Department of Surgery and Radiology, Faculty of Veterinary Medicine University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Navid chavoshi","family":"tehrani","sequence":"additional","affiliation":[{"name":"Veterinarian (DVM), Graduated From Faculty of Veterinary Medicine, University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4709-3538","authenticated-orcid":false,"given":"Muhammad shahbazi","family":"dastjerdi","sequence":"additional","affiliation":[{"name":"Department of Surgery and Radiology, Faculty of Veterinary Medicine University of Tehran  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,25]]},"reference":[{"key":"e_1_2_11_2_1","volume-title":"Exotic Animal Formulary\u2014E\u2010Book","author":"Carpenter J.
