TI  - Comparison of Dorsoventral Erect and Ventrodorsal Supine Radiographic Views for 
      the Evaluation of Intracoelomic Organs in Clinically Normal African Grey Parrots 
      (Psittacus erithacus).

AB  - Standard positioning for radiographic evaluation may require sedation and can be 
      deleterious in critically ill birds. A prospective crossover study was performed 
      in 15 clinically normal African grey parrots (Psittacus erithacus) to describe an 
      alternative, unrestrained radiographic view. Whole-body radiographs were obtained 
      in unrestrained dorsoventral erect (DVE) views and in anesthetized ventrodorsal 
      supine (VDS) views. Visualization of various anatomic items in each view was 
      scored by 3 observers. The surface area of the air sacs and the width of the 
      heart, liver, thorax, and cardiohepatic waist were measured in DVE and VDS views. 
      Measurements were obtained by 3 observers, and 1 observer repeated the 
      measurements twice. Intraobserver and interobserver agreement were assessed. 
      Major rotation of the coelom and superimposition of the limbs over the coelom 
      were, respectively, observed in 4 of 15 (27%) and 15 of 15 (100%) of the DVE 
      views and not observed in VDS views. The evaluation of the respiratory tract 
      structures was considered limited in DVE views compared with VDS views, and the 
      surface areas of the air sacs were significantly smaller. The proventriculus and 
      ventriculus were more visible in the DVE view. The visualization of the heart was 
      not significantly different between the 2 views. The absolute measures of heart, 
      liver, and cardiohepatic waist width were significantly larger in the DVE view 
      compared with the VDS view. Moderate intraobserver and interobserver agreement 
      was observed in the evaluation of the 2 views. In conclusion, the DVE view could 
      be adequate to assess the heart and the upper digestive tract. This positioning 
      is likely to provide clinically relevant information for cases in which general 
      anesthesia or dorsal recumbency is contraindicated.
