Example images of subject 2 showing three consecutive slices of the PCL from four MR imaging sequences, including i) PD TSE sagittal, ii) PD FS TSE sagittal, iii) PD FS TSE axial, iv) PD FS TSE coronal. This subject was a 28-year old male with a chronic PCL injury from a fall. On original imaging evaluation the radiologist noted minimal focal increased signal within the mid PCL substance likely indicative of mild scarring and/or degeneration. However, a secondary review of the images identified some irregularity in the proximal region of the PCL (white arrows)
