There was considerable variation in image interpretation among observers and between use of various imaging modalities; these imaging techniques should be considered complementary in assessment of dogs with DAWS.

This study was performed to provide a detailed atlas of the normal arterial and venous canine vasculature in the cranial abdomen by dual-phase computed tomographic angiography. Five adult beagles were positioned in dorsal recumbency on a multislice helical CT scanner. An unenhanced survey CT scan from the diaphragm to the pelvic inlet was performed. Bolus-tracking software was used for the dual-phase angiogram, and contrast medium was administered in a cephalic vein. The arterial phase was scanned from the mid-abdomen to the cranial aspect of the diaphragm; the portal phase was scanned a few seconds after the arterial phase in the opposite direction. The DICOM studies from all dogs were analysed. Representative images were selected and anatomic structures labelled. Maximum intensity projections and three-dimensional images were generated using software techniques. A detailed atlas of the venous and arterial vasculature of the cranial canine abdomen was created with the help of bolus-tracking dual-phase computed tomographic angiography (CTA). Practitioners can use this anatomic atlas with its detailed venous and arterial phase CT angiograms of the canine cranial abdomen to compare normal versus abnormal vascular anatomy.

CTA was useful for seeing articular cartilage and both CTA and MRA were useful for seeing the normal glenohumeral ligaments; however, further research is needed to examine each technique's sensitivity for diagnosing the pathology of these ligaments and any associated lesions of the capsule, tendon, and bone, and for determining the clinical importance of CTA for evaluating loose fragments or osteochondral lesions.
