Clinical Trial Summary

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.


Description:

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.

Outcome

Type Measure Description Time frame Safety issue
Primary Modified Whole-Organ Magnetic Resonance Imaging Score (WORMS) Modified Whole-Organ Magnetic Resonance Imaging Score (WORMS) of the knee is a validated instrument utilized to grade structural abnormalities found in MRI.
Only the cartilage sub-score of the full WORMS will be scored in the study. Cartilage will be scored on a range from 0-6 for 6 different regional subdivisions for a minimum score of 0 and maximum score of 36. A lower score is considered a better outcome, with a score of 0 equating to normal thickness and signal of cartilage.
