| Abstract | 「要旨」 中枢性めまいへのIMPシンチグラフィの応用の可能性の検討のため, 正常者8名のIMPの両側小脳半球への集積差を左右差指数(A.I.)で求め, 中枢性めまい患者のA.I.と比較した. また推定病巣別にIMPシンチグラフィ所見とX線CT所見を比較検討した. 正常者のA.I.は5.8±2.1%で, 中枢性めまい36症例では12.7±7.5%であった. A.I. 8%以上をIMPシンチグラフィ上の異常所見とすると, 小脳半球に病巣の推定できる14症例中11例が, 小脳虫部を含めた小脳全体では20症例中16例が異常と判定できた. 脳幹では11症例中7例が, 椎骨脳底動脈不全症では5例中4例が異常と判定された. IMPシンチグラフィは, 小脳半球に病巣の推定できる中枢性めまい患者においては臨床症状とよく一致し, X線CTよりも有用な検査法である可能性が示唆された. |

| Abstract | [Summary] To study the application of cerebral blood flow scintigraphy with 123I-IMP for the evaluation of central dizziness, the difference in 123I-IMP accumulation between the right and left cerebellar hemispheres was determined as an asymmetry index (A.I.) in 8 normal subjects and compared with A.I. from patients with central dizziness. According to estimated lesions, 123I-IMP findings were compared with CT findings. The normal subjects had A.I. of 5.8+-2.1%, whereas 36 patients with central dizziness had A.I. of 12.7+-7.5%. On the basis of an A.I. of 8% or more as an abnormal finding on IMP scintigraphy, 11 of the 14 patients with estimated lesions of cerebellar hemispheres and 16 of the 20 with those of the whole cerebellum including the vermis were evaluated to have had abnormalities. Seven of 11 with estimated lesions of the brainstem and 4 of 5 with vertebrobasilar arterial insufficiency were evaluated to have had abnormalities. The findings of 123I-IMP cerebral blood flow scintigraphy were in good agreement with clinical symptoms in patients with central dizziness with estimated lesions of the cerebellar hemispheres, suggesting the possibility that this method is more useful than CT. |
