MR imaging of the rotator cuff

Area of Science:

• Radiology
• Orthopedic Imaging
• Musculoskeletal MRI

Background:

• Rotator cuff pathology is a common cause of shoulder pain and dysfunction.
• Accurate diagnosis is crucial for effective treatment planning.
• Magnetic resonance (MR) imaging has become the gold standard for evaluating the rotator cuff.

Purpose of the Study:

• To review the role of MR imaging in evaluating rotator cuff pathology.
• To discuss current MR techniques for assessing rotator cuff abnormalities.
• To highlight the importance of MR imaging in identifying conditions that mimic rotator cuff disease.

Main Methods:

• Review of current literature on MR imaging of the rotator cuff.
• Discussion of fast spin-echo techniques with and without fat suppression.
• Consideration of MR arthrography and specialized positioning (e.g., abduction and external rotation - ABER).

Main Results:

• Fast spin-echo MR imaging with fat suppression provides accurate characterization of rotator cuff tendinous and myotendinous abnormalities.
• MR imaging effectively identifies impingement disorders, tendon degeneration, instability, and trauma.
• MR imaging can differentiate rotator cuff pathology from other mimicking lesions.

Conclusions:

• MR imaging is the optimal modality for evaluating suspected rotator cuff pathology.
• Current MR techniques allow for detailed assessment of rotator cuff structures.
• MR imaging plays a vital role in diagnosing the multifactorial nature of rotator cuff disease.
