MRI Long Bone Upper Extremity (Anatomy & Pathology) - Video Lesson

Hey, everyone. Welcome to today's lesson on MRI for the long bones of the upper extremity. In this lesson, we will review anatomy on different planes of MRI imaging and identify bony and soft tissue structures relating to the humerus, ulna, and radius, and discuss common pathologies associated with these scans. Let's get started. The humerus extends from the shoulder to the elbow and includes a rounded head that articulates with the glenoid cavity of the scapula. On this coronal view, we are looking at an anterior slice position. A small portion of the humeral head is visible. Moving posteriorly, the rounded humeral head and surgical neck are visible. The surgical neck is important as it is a common fracture site. The deltoid muscle is located on the lateral side of the shoulder, and the bicep brachii muscle can be seen vertically. We know this is the bicep brachii as this is an anterior slice. On this slice, starting in the
