| Abstract | 「要旨」 脳血管障害20例に計22回のN-isopropyl-p-I-123-iodoamphetamine (IMP) による脳血流検査を行い, X線CT (XCT) , ポジトロンCT (PCT) との比較検討を行った. IMPとXCTとの比較ではIMPの有所見率は, 20/22 (91%) とXCTに比し低かった. しかしながら, IMPでは16検査でXCTよりも病変範囲が広く, 9検査でCrossed cerebellar diaschisisが観察された. つぎにPCTの行われている15症例17検査におけるIMPとPCTとの比較ではIMPの有所見率は, 16/17 (94%) とPCTに比し低かったが, 病変の指摘しえた16検査の所見は, PCTとよく一致しており, より正確な病変範囲の把握, 形態変化を伴わない機能的変化をとらえるのに有用と思われた. また, 浅側頭動脈-中大脳動脈吻合術の経過観察にも有用であった. |

| Abstract | [Summary] Twenty-two brain perfusion studies were performed on 20 patients with cerebrovascular disorders using N-isopropyl-p-I-123-Iodoamphetamin (IMP) . X ray computed tomography (XCT) and positron computed tomography (PCT) were compared with IMP brain scans to evaluate the clinical significance of IMP for the brain perfusion imaging agent. Compared with XCT, the positive rate of IMP was 20/22 (91%) and was lower than that of XCT. But perfusion defect was larger than the lesion seen on XCT in 16 studies, and crossed cerebellar diaschisis was observed in 9 studies. Compared with PCT, the positive rate of IMP was 16/17 (94%) and was lower than that of PCT. But IMP findings agreed very well with those of PCT in 16 IMP positive studies. These findings showed the usefulness of IMP to demonstrate exact extent of the lesions and the functional changes which were not accompanied by morphological changes. After superficial temporal artery-middle cerebral artery anastomosis, IMP scan showed reperfusion in previously ischemic area. |
