On oblique sagittal plane, a conventional spin echo (CSE) pulse sequence (TR=500ms, TE=20ms) was used in 121 patients with 4 excitations, 256\u00d7192 matrix and 150mm field of view, whereas a fast spin echo (FSE) sequence (TR=2500ms, TE=22/90ms) was used in 244 patients with 3 excitations, 256\u00d7190 matrix and 150mm field of view. There was no remarkable diference in delineation of the disk between CSE and FSE pulse sequences according to a subjective judgement by three trained observers. On MRI, 253 joints (34.7%) had normal superior disk position ; 230 joints (31.5%) showed anterior disk displacement with reduction (completely anterior 105 joints, anterolateral rotational 36 joints, anteromedial rotational 8 joints, partially lateral anterior 67 joints, partially medial anterior 14 joints, respectively) and 212 joints (29.0%) showed anterior disk displacement without reduction (completely anterior 145 joints, anterolateral rotational 48 joints, anteromedial rotational 14 joints, partially lateral anterior 5 joints, respectively) ; 16 joints (2.2%) showed lateral sideways displacement and 19 joints (2.6%) showed medial sideways displacement. On T2-weighted image, we defined a more hyperintense area in the joint than the bone marrow as a joint effusion. One hundred fourty-one joints (19.3%) had line-shaped effusions and 180 joints (24.7%) had larger amount of effusions, whereas 365 joints (50.0%) had no effusions.", "subitem_description_type":
