MRI for SI joints, Sacrum, and Coccyx (Procedures) - Video Lesson

Hey everyone. Welcome to today's lesson on the MRI of the sacrum, coccyx, and sacroiliac joints. In this lesson, will discuss patient setup and slice positioning, indications for this exam, MRI anatomy and some imaging challenges associated with this study. Let's get started. An MRI of the sacrum, coccyx, and sacroiliac, or SI joints, is used to assess the bony details, joints, and soft tissues of these structures. Common indications include sacroiliitis, Infection, degenerative or osteoarthritis, and tumors or neoplasms. An MRI may be ordered because it demonstrates subtle details and structural changes not visible on a radiograph or computed tomography scan. Patients needing a sacrum, coccyx, or SI joint study will typically be positioned on the
