| Abstract | 「要旨」865症例, 1078検査を対象として67Gaの肩関節およびその周囲への集積を左右で比較した. 約50%の症例で左右差は認めなかった. 約40%は右側に, 約10%は左側に集積の相対的亢進が認められた. 2回以上67Gaシンチグラフィを施行した症例のうち約30%の症例は経過中に左右差に変化が見られた. 左右差の原因は, 不明なものが多かったが, 約1/8の症例に骨転移, 放射線の照射, 麻痺による筋肉の萎縮, 手術が原因と推定された. 99mTc-MDPの集積と比較したとき, 67Gaの集積の左右差を認める範囲はより広範囲であり, 軟部組織の描出は優れていた. 99mTc-MDPの集積は67Ga集積の中央部にはっきりとした左右差として認められた. 骨, 関節が異常の時は99mTc-MDPは67Gaよりも診断能が高かった. 67Gaと99mTc-MDPの集積増多側は72%で一致しており, 両者の集積機序には同じfactorが関与しているものと考えられた. |

| Abstract | [Summary] 67Ga scintigraphy was performed in 865 patients, and in 1078 examinations. 67Ga accumulation was evaluated retrospectively for asymmetric accumulation in the shoulders. Approximately 50% of patients showed no asymmetric distribution of 67Ga in the shoulders. About 40% of patients showed increased accumulation in the right side and about 10% of patients showed increased accumulation in the left side. A change of 67Ga distribution in the shoulder joints was recgnized in about 30% of patients during the follow-up study. Reasons for asymmetric distribution of 67Ga in the shoulders were considered to be due to bone metastasis, changes of local blood flow, edema, irradiation, muscle atrophy after cerebral paralysis, and operation. 67Ga scintigraphy showed a broader range and more prominent accumulation in the soft tissues around the shoulder joint than 99mTc-MDP scintigraphy. The accumulation of 99mTc-MDP was recognized to be in the center of the region of 67Ga accumulation. 99mTc-MDP scintigraphy showed more prominently increased accumulation than 67Ga scintigraphy in patients with osseous lesions. Similar factors appeared to have had an influence on the abnormal accumulation of 67Ga and 99mTc-MDP around the shoulder joint. |
