Crimps is a feature of collagenous tissues that has biomechanical significance. Utilizing ultra-high field strength MRI (11.7T), human crimp morphology is visible for the first time. Additionally, we provide the first description of macroscopic crimps (macrocrimps) on MRI with histologic correlation, which are visible in unloaded tendon on 3T MRI. Macrocrimps change tendon signal intensity and can potentially alter T2 measurements of tendons between loaded and unloaded states.
