MRI Techniques for Shoulder Labral Tear
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to compare two MRI techniques to determine which better detects shoulder issues, such as labral tears and cartilage problems. Participants will undergo both the standard MR arthrogram, which requires dye injection and uses a 1.5 Tesla magnet, and a newer non-contrast MRI with a 3 Tesla magnet. The goal is to determine if the non-contrast MRI can be as effective without dye. The study seeks participants likely to need labral surgery and who have ongoing shoulder problems. As an unphased trial, it offers participants the opportunity to contribute to advancements in MRI technology for shoulder diagnostics.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the research team or your doctor.
What prior data suggests that these MRI techniques are safe for detecting shoulder labral and cartilage pathology?
Research has shown that both imaging methods used in this trial are safe for people. The 1.5 Tesla magnet MR arthrography is generally safe, though some patients might experience discomfort or pain from the contrast dye injected during the procedure. Previous studies have noted this, but it is usually manageable.
For the 3 Tesla magnet non-contrast MRI, studies indicate it is also safe and does not require contrast dye. This reduces the chances of side effects compared to MR arthrography. Overall, both imaging techniques are widely used in medicine and are considered safe for identifying shoulder problems.12345Why are researchers excited about this trial?
Researchers are excited about these MRI techniques because they aim to improve the detection of shoulder labral tears. Traditional methods often use 1.5 Tesla MR arthrography, which involves injecting a contrast dye into the joint. However, this study is testing a 3 Tesla non-contrast MRI, which doesn’t require any dye. This not only makes the process less invasive and more comfortable for patients, but the stronger magnet of the 3 Tesla MRI could potentially provide clearer, more detailed images, leading to better diagnosis and treatment planning.
What evidence suggests that these MRI techniques are effective for detecting shoulder labral tears?
Research has shown that MR arthrography, a type of MRI scan with contrast dye using a 1.5 Tesla magnet, effectively detects shoulder issues. It correctly identifies actual cases 88-100% of the time and rules out false ones 89-93% of the time for problems with the glenoid labrum, a part of the shoulder. This makes it quite reliable.
In this trial, participants will undergo both MR arthrography with a 1.5 Tesla magnet and a non-contrast MRI using a 3 Tesla magnet. Studies indicate that the non-contrast MRI excels at detecting labral tears, achieving 100% accuracy for tears in the front part of the labrum. This suggests that both scanning methods are strong options for identifying shoulder problems, each with distinct advantages.678910Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for English-speaking adults aged 18-65 who likely need labral surgery or have chronic shoulder issues. It's not for those with recent trauma or who can't complete both types of MRI scans.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- 1.5 Tesla magnet MR arthrography
- 3 Tesla magnet non-contrast MRI
Trial Overview
The study compares two MRI techniques: a standard MR arthrogram using a 1.5 Tesla magnet and a newer non-contrast method with a stronger, 3 Tesla magnet, to see which better detects shoulder damage.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Patients will be imaged with standard of care MRI shoulder arthrogram on a 1.5 T magnet and additionally with non-contrast MRI of the shoulder on a 3 T magnet. All patients will be dually imaged. Initial imaging will utilize the standard of care, and, subsequently, patients will be brought back within 2 weeks, for non-contrast MRI as part of the study protocol
