Advanced Imaging of the Forelimb: Use of Musculoskeletal Ultrasound and MRI of the Shoulder and Brachial Plexus.

Abstract

Advanced imaging (ultrasound, computed tomography, MRI) is a key component in defining and localizing the underlying cause of forelimb lameness. Given the propensity of soft tissue injury/disease of the shoulder and brachial plexus, ultrasound and MRI are of particular utility in defining tendinous, muscular, and nerve lesions. An advanced knowledge of shoulder and brachial plexus anatomy is necessary for both image acquisition and interpretation. To determine clinical significance, interpretation of both normal anatomy and suspected pathology must be correlated with clinical signs and orthopedic examination findings.
