On oblique sagittal plane, a conventional spin echo (CSE) pulse sequence (TR=500ms, TE=20ms) was used in 121 patients with 4 excitations, 256×192 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, 256×190 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":"Abstract"},{"subitem_description":"1994年4月より1996年4月までの間に、のベ365例の顎関節症患者のMRI検査を施行した｡1.0T(tesla)の磁場強度の装置を用い、ヘッドコイルを使用し、スライス厚3mm･スライスギャップなしにて軸位断･冠状断･矢状断を撮像した｡矢状断については、121例にconventional spin echo(CSE)法(TR＝500ms、TE＝20ms)を使用し、number ofexcitation(NEX、加算回数)4回、マトリクス256×192、field of view(FOV)を150mmとした｡また244例にfastspin echo(FSE)法(TR=2500ms、TE＝22/90ms)を使用し、NEX
