Which imaging modality provides best evaluation for suspected rotator cuff tears when persistent symptoms remain after initial management?

• A. X-ray
• B. CT
• C. Ultrasound
• D. MRI

Answer: (D)

When persistent shoulder symptoms raise suspicion for a rotator cuff tear, you need imaging that can clearly visualize the soft tissues of the shoulder. MRI provides high-resolution images of the rotator cuff tendons and surrounding muscles, allowing you to determine whether a tear is present, and if so, its type (partial- or full-thickness), size, and degree of retraction. It also assesses muscle quality, including atrophy and fatty degeneration, which are important for predicting prognosis and guiding treatment. In addition, MRI can evaluate related structures such as the biceps tendon, labrum, and the acromiohumeral joint, giving a complete picture for planning management or surgery. Other modalities have limitations: X-ray mainly shows bone and calcifications, CT excels at bone detail but not soft tissue, and ultrasound, while useful and dynamic, depends on the operator and may miss some partial-thickness tears. Thus MRI offers the most comprehensive assessment when symptoms persist after initial management.
