A Study of Diagnostic Accuracy of The Mi-eye2™ Compared to Magnetic Resonance Imaging in Knee Arthroscopy Patients


About this study

The objective of this study is to investigate the clinical utility of the mi-eye 2™ device. This will be done by measuring the frequency with which the MRI and mi-eye 2™, respectively, change the Investigator’s primary diagnosis, confidence in diagnosis and management plan, in a routine clinical setting.
