  Purpose
This study will prospectively compare the findings of two diagnostic tests, Direct Magnetic Resonance Arthrography(MRA) and Indirect MRA, to the findings during shoulder arthroscopy in patients with shoulder pain. The sensitivity and specificity of both Direct and Indirect MRA's in diagnosing specific pathologies of the shoulder will be determined using shoulder arthroscopy as the gold standard.

Condition Intervention
Shoulder Pain Procedure: Indirect MRA of shoulder Drug: Gadopentetate Dimeglumine

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Prospective Comparison of Indirect and Direct MR Arthrography of the Shoulder Using Arthroscopic Correlation

Primary Outcome Measures:
  • Sensitivity and specificity of Direct and Indirect MR Arthrograms in detecting pathologies of the shoulder when compared with Arthroscopic findings. [ Time Frame: Patients will be foollowed from their Indirect MRA to their arthoscopic shoulder surgery, approximately one month from time of consent ]
    This study will compare the findings of the Indirect MRA and the retrospective data of the Direct MRA, to the results obtained during their arthroscopic shoulder surgery in patients with shoulder pain. The incidence of partial and full thickness rotator cuff tears, long head biceps dislocation/tearing, and grade IV cartilage lesions will be recorded for each type of MRA of the shoulder. The sensitivity and specificity of both direct and indirect MR arthrography in diagnosing shoulder problems will be determined by what was actually visualized during their arthroscopic shoulder surgery.

Arms Assigned Interventions
Experimental: Indirect MRA
After patient has signed consent and had blood tests to ensure normal kidney function (BUN and Creatinine) as well as serum and urine pregnancy tests for females to ensure there is no pregnancy, the patient will have an Indirect MRA. The participant will be weighed and the correct dose of 0.1 mmol/kg calculated. An IV will be inserted into participant's arm. The gadopentetate dimeglumine will be injected into the IV and the patient will be asked to gently exercise the shoulder (small windmills and flexion/extension) for 5 minutes. The patients then undergo MRI imaging 15-30 minutes after the injection. Contraindications include known allergy to gadopentetate dimeglumine, and renal failure with creatinine clearance of less than 30ml/min.

Detailed Description:
Direct MR arthrography (MRA) requires the injection of a contrast agent into the shoulder under fluoroscopic or ultrasound guidance, followed by magnetic resonance imaging (MRI). This is invasive, risks infection, and requires time and resources. It has recently been shown that the intravenous administration of gadopentetate dimeglumine enhances the joint cavity during an MRI and thus indirectly produces an arthrographic effect(Indirect MRA). The study will enroll patients who have already had a Direct MRA as part of their standard of care diagnostic test for shoulder pain, if it is determined by their surgeon that arthroscopic surgery is indicated they will be asked if they would be willing to have an Indirect MRA prior to their arthroscopic surgery. The patient will need to have a blood test(BUN and Creatinine)done to ensure kidney function is normal, and a serum and urine pregnancy test, if female, to ensure there is no pregnancy, prior to the completion of the Indirect MRA. After the patient's scheduled shoulder arthroscopic surgery, the results of the two MR arthrography techniques will be compared for sensitivity and specificity in detecting partial and full thickness rotator cuff tears, labral tears, long head biceps dislocation/tearing, and grade IV cartilage lesions by comparing the results to the actual arthroscopic findings. The Direct MR arthrography and arthroscopic surgery are standard of care and would occur regardless of this study, the Indirect MR arthrography is the diagnostic intervention that is study-related.
