| Abstract | 「I. はじめに」Mooreが初めて1948年放射性diiodofluoresceinを使って脳腫瘍を診断して以来, 放射性同位元素による脳腫瘍の診断は脳神経外科領域には欠くことのできない重要な検査法となった. われわれは当教室の過去5年間において経験した脳腫瘍のうち132例について計209回の脳スキャンを施行したが, それらの結果を詳細に検討し, さらに頭部単純撮影, 脳血管撮影, 気脳・気脳室撮影, 脳波等の所見と種々の面から比較し脳腫瘍に対する脳スキャンの診断価値について検討を行った. 「II. 症例および方法」症例は東京医科歯科大学脳神経外科学教室において昭和45年7月から昭和50年7月までの5年間に経験した脳腫瘍132例である. 症例のうちわけはTable 1に示すごとく神経膠腫27例で最も多く, その他脳下垂体腺腫21例, 髄膜腫18例, 脳動静脈奇形18例等であった. 年齢別に見ると30歳台が最も多く25%を占めた. 15歳以下の小児は24例で18%を占めた, 男女別では男性が79例(59.8%), 女性が53例(40.2%)でやや男性が多かった. |

| Abstract | [Summary] The use of radioactive compounds for the diagnosis has become practical in the field of neurosurgery with the advent of short physical half-life or low energy or both. This paper is based on experience at Department of Neurosurgery, Tokyo Medical and Dental University Hospital. We performed 99mTc-pertechnetate brain scanning 209 times and 169Yb-DTPA cisternography 16 times on 132 brain tumors, in which the diagnosis was confirmed by operation or autopsy. The scanning gave positive results in 86.4%, doubtful positive in 9.1% and negative in 4.5%. High positiveness were obtained in meningiomas, acoustic neurinomas, and metastatic tumors and those poorly localized were midline tumors, tumors located at the base of the skull, and those of pediatric age group. The abnormalities were disclosed in 55% of cases in plain skull X-rays, 92% in cerebral angiography, 83% in air study, and 67% in EEG. There was a great difference in the positiveness of EEG between in children and adults. Former were 40% in positiveness, latter, 70%. There was a correlation between the vascularity of brain tumors and the positiveness of brain scan. Diagnostic value of brain scanning are compared with that of other diagnostic procedures. The results are that the values in the "localization diagnosis" were superior to other diagnostic adjuncts in 55%, equal in 33% and inferior in 12%. The values in the "nature" diagnosis were superior in 24%, equal in 48% and inferior in 28%. We conclude that the scans are the most useful in brain tumor localization. |
