Abstract
Supraspinatus calcifying tendinosis is an uncommon finding in dogs. Although its radiographic appearance has been described previously, radiographs alone do not provide detailed information about the tendon parenchyma. Tendon ultrasonography has been widely applied for the diagnosis of human tendinosis, but it remains underused in dogs. This article reviews the ultrasonographic technique and variable appearance of canine supraspinatus calcifying tendinosis observed in 33 tendons. The ultrasonographic findings are described. The most common ultrasonographic finding was a hyperechoic area accompanied by distal acoustic shadowing. No relationship with bicipital tenosynovitis was found. A color Doppler examination was possible in only five of the tendons, revealing no blood flow in those tendons. There was evidence that the presence of a hypoechoic area surrounding the calcification was related to clinical signs of pain, suggesting an active inflammatory process. Ultrasonography was an excellent technique to evaluate lesions of the supraspinatus tendon and it revealed details not apparent on radiographs.

Abstract
Increasing sports participation, and the inevitable sports injury, is a significant contributor to total healthcare expenditure in the United States. With sports-related injury ever increasing, and technology rapidly expanding in the areas of diagnosis and treatment of musculoskeletal trauma, a continual revisiting of the latest in technology is critical for the sports physician. Advances particularly in the areas of magnetic resonance imaging, diagnostic office ultrasound, and 3-dimensional reconstruction computed tomography, offer the clinician a myriad of diagnostic options in patient evaluation. Care must be exercised, however, as one pursues additional radiographic data in the patient care arena. The information must be interpreted with a firm foundation and understanding of not only the patient history and physical examination, but also the availability, indications, contraindications, sensitivity, specificity, and even the cost implications of the great spectrum of diagnostic options.
