7T MRI to Evaluate Cartilage Defects in the Knee

Improving Non-Invasive Diagnosis and Grading of Cartilage Defects in the Knee - Accuracy of Ultra High Field 7-Tesla MRI as Compared With Arthroscopy

The investigators propose to prospectively evaluate the accuracy of a novel 7-Tesla (7T) knee MRI protocol for the detection and grading of cartilage lesions in the knee, which is a significant limitation of current MRI techniques.

The investigators hypothesize that 7T MRI will be ~ 80% sensitive for detection of cartilaginous lesions. This will be tested in a prospective multi-reader study of 100 patients who are scheduled to have knee arthroscopy. Patients will have two MRIs of the knee: one standard of care and one experimental 7T MRI. Subjects will visit at one time point prior to scheduled knee arthroscopy, for a session time of ~1-2 hours for a single 7T MRI scan.

Inclusion Criteria:

• Confirmed Knee Symptomatology
• Scheduled Arthroscopic Treatment of Knee
• Adult (equal or greater than 18 years of age)

Exclusion Criteria:

• Active infections
• Less than 18 years of age
• Pregnant
