Abstract: The aim of the present study was to evaluate the feasibility of contrast-enhanced computed tomography for organ morphology and perfusion in five captive terrapins. Native scans were performed and afterwards an iodinated non-ionic contrast media was manually administered through the jugular vein catheter. Post-contrast CT scans were taken 20 (T20), 60 (T60) and 180 (T180) seconds after the contrast medium administration. Maximum contrast enhancement of the kidneys and the liver was detected at T20 and T60, respectively. The gall bladder content, the urinary bladder content and ovarian follicles were all without contrast enhancement in all five terrapins. Gall bladder wall thickness was 0.9 mm in all terrapins. Enhancement of the gall bladder wall in post-contrast studies was considered excellent, good or poor in two terrapins, two terrapins and one terrapin, respectively, with a mean score of 1.8 ± 0.84 over all contrast studies. Enhancement of the ureters in post-contrast studies was considered excellent in all terrapins in all contrast studies. Peak aortic enhancement was reached 20 seconds after contrast medium administration with the peak enhancement of 213.5 ± 41 HU in four terrapins and 560 HU in one terrapin. Peak hepatic vein enhancement after contrast medium administration was recorded 20 and 60 seconds in two and three terrapins, respectively. In conclusion, contrast-enhanced computed tomography proved to be a valuable method for clinical examination of the liver, gall bladder, kidneys, ureters, urinary bladder and ovarian follicles in red-eared terrapins.
