27-year-old male patient with normal knee cartilage. Normal cartilage on PDW-SPAIR (a) (3.0 Tesla, TR/TE=415msec/8msec, Slice Thickness=3mm), T2 mapping (b) (3.0 Tesla, TR/TE=2400 msec/15, 30,45,60,75,90msec, Slice Thickness = 3mm) and DWI image (c) (3.0 Tesla, TR/TE = 2000 msec/70 msec, Slice Thickness = 3mm) were expressed as a continuous cartilage and uniform signal (arrows).
