The primary objective of the current study is to investigate the value of rMRI in diagnosing intraarticular injury to the shoulder. Specifically, this project aims to determine whether rMRI can be used to evaluate for labral pathology, and whether the polar-coordinate based sequences provide further diagnostic value compared to traditional planar sequences. This primary objective will be accomplished by radiographically evaluating the shoulders of patients with clinical examinations concerning for shoulder pathology using MRI, MRA, rMRI and rMRA, and using the results of the images to compare incidence of tears found on the different imaging modalities as well as to compare sensitivity and specificity using intraoperative findings as a gold standard.
A secondary goal of this project is to qualitatively evaluate labral tears using radial sequence MRIs by developing a new classification system for labral tears based on the location and morphology of the labral injury. This system will be applied to the MRI and rMRI data and the tear types enumerated for each imaging modality.
Study group: All patients 18 and older who are being treated by the Drs. Tashjian, Burks and Greis at the University of Utah with complaints of shoulder instability or shoulder pain are eligible for the study.
Pilot group: Patients between the ages of 18 and 30 presenting to the clinics of Drs. Tashjian, Burks and Greis who do not have a history of shoulder pain or instability will be eligible to be pilot participants.
Study group: Patients may be excluded if there is no clinical reason for an MRI evaluation. Patients are also to be excluded from the study if they have already received a shoulder MRI from an outside institution/facility. Additionally, we will exclude anyone who knows they cannot receive an MRI for any reason including but not limited to retained metal (such as pacemakers, aneurysm clips, deep brain stimulators, etc), or previously documented allergic reactions to contrast. Patients also are to be excluded if they have had previous fracture fixation in the shoulder imaged.
Pilot group: Patients will be excluded if they have a history of shoulder pain or instability or are outside the age range of 18-30. Additionally, we will exclude anyone who knows they cannot receive an MRI for any reason including but not limited to retained metal (such as pacemakers, aneurysm clips, deep brain stimulators, etc). Patients also are to be excluded if they have had previous fracture fixation in the shoulder imaged.
