title: Radiographic anatomy of the thorax and abdomen of the common marmoset (Callithrix jacchus).
abstract: A standard radiographic procedure was developed for the thorax and abdomen in the common marmoset. A description and reference values for the corresponding radiographic anatomy are given. Radiographs were obtained from 17 anaesthetized healthy mature marmosets ranging from 1.5 to 9 years and 328 to 506 g. Left-to-right lateral recumbent and ventrodorsal whole-body radiographs made at end inspiration are recommended. Images of the heart, lungs, liver, gastric axis, and at least one kidney could be evaluated consistently. A generalized interstitial/peribronchial pattern was normally present. The mean of the vertebral heart size +/- SD on dorsoventral or ventrodorsal views was 9.42 (+/- 0.44), ranging from 8.8 to 10.6. Abdominal detail was generally poor. The gastrointestinal structures could often only be identified because of their luminal gas. The right liver lobes were prominent and extended caudally beyond the costal arch. The pylorus was in a central position and the spleen could not be distinguished. Additionally, pancreas, lymph nodes, urinary bladder, and ureters were not identified. A statistically significant difference (P < or = 0.05) between female and male kidney length existed. This study emphasizes that significant species differences exist, and simply applying canine or feline radiographic interpretation will result in misinterpretation.
