Brief Summary:
The purpose of this study is to evaluate the diagnostic performance of three Tesla magnetic resonance imaging (3T MRI) compared to magnetic resonance arthrogram (MR arthrogram) in diagnosing superior labrum anterior posterior (SLAP) lesions. We hypothesize that 3T MRI will have non-inferior sensitivity compared to MR arthrogram in diagnosing SLAP lesions utilizing arthroscopy as our gold standard test. To evaluate our hypothesis, the investigators will include patients suspected to have a SLAP lesion on history and physical examination by a fellowship trained orthopaedic surgery. Patients will be offered advanced imaging (both 3T MRI and MR arthrogram) as well as arthroscopy for definitive diagnosis and treatment after consent is obtained. A fellowship trained musculoskeletal radiologist will perform and interpret the magnetic resonance tests while the arthroscopy will be performed by orthopaedic surgeons. The diagnostic characteristics of each imaging modality, including sensitivity, specificity, negative predictive value, and positive predictive value, will be compared to each other.
