A prospective study was performed in 12 green iguanas (Iguana iguana) to compare the radiographic appearance of coelomic viscera. Five radiographic projections (views) of the coelom were obtained: dorsoventral, right lateral vertical beam, left lateral vertical beam, right lateral horizontal beam, and left lateral horizontal beam. One week later, the same radiographic projections were obtained after oral administration of barium. In 4 of the 12 green iguanas, an additional vertical beam ventrodorsal view was obtained. In comparing lateral projections, lung, liver, and gonads were best imaged in horizontal beam lateral projections, before distention of the stomach with barium, whereas the gastrointestinal tract including the colon was best visualized in vertical beam lateral projections. The shape and size of the cardiac silhouette was considered equivalent between analogous lateral projections in most green iguanas (10 [83%] of 12). In comparing ventrodorsal and dorsoventral projections, the ventrodorsal projections improved visibility of the cardiac silhouette and lung in 4 (100%) of 4 green iguanas, while reducing cardiac length. Dorsoventral projections were preferred for the evaluation of the gastrointestinal tract. This study demonstrates that radiographic beam orientation and patient position result in obvious radiographic differences of the iguanid coelom and that projections are not interchangeable.
