For interpreting radiologists and clinicians, evaluation of an injured knee using MRI requires knowledge of the proper imaging techniques, normal and aberrant anatomy, and the clinical significance of detected abnormalities. A coronal, proton-density (PD) MRI scan of the medial collateral ligament (MCL) is seen below.rade II medial collateral ligament tear seen on a coronal proton density image shows slight thickening of the medial collateral ligament and separation from the underlying cortices (arrows).
