Joint Pain Undergoes a Transition in Accordance with Signal Changes of Bones Detected by MRI in Hip Osteoarthritis

Fig. (4) MRI showing high signal change in the entire femoral head and acetabulum. Broad low intensity signal by T1-weighted image (a) and high intensity by T2-STIR (arrows) (b) in the right femoral head and acetabulum. Note that there was continuous joint pain when MRI was performed.
