| Abstract | 「要旨」脳内出血20症例にて123I-IMPによる脳SPECTを撮像し, 同時期に施行したX線CTの所見と対比し, IMP-SPECTの臨床的意義について検討した. X線CTにおける高吸収域をCT-Central area, 低〜正吸収域をCT-Peripheral area, IMP-SPECTにおける欠損をIMP-Central area, 摂取低下をIMP-Peripheral areaとした. またIMP-Peripheral areaの初期分布と晩期分布を比較し, 視覚的に3群に分類し, X線CTより求めた血腫と比較した. IMP-Central areaはCT-Central areaとほぼ一致した血腫およびその吸収に伴う線維組織化による領域であり, 脳血流低下が著明であった. IMP-Peripheral areaはCT-Peripheral areaより広範囲に認められ, 血腫の大きさにより経時的動態が異なっていた. このことにより, IMP-SPECTにより脳内出血に伴う脳障害領域を推定できうると考えられた. |

| Abstract | [Summary] To evaluate cerebral blood flow in intracerebral hemorrhage, we performed single photon emission computed tomography using N-isopropyl[I-123]p-iodoamphetamine (IMP-SPECT) in 20 patients. IMP-SPECT was carried out using rotating gamma camera at 30 min, and 4 hrs after injection. The results were compared with those by computed tomography (CT) . In all cases, the extent of hematoma by IMP-SPECT was larger than that of CT. All cases were divided into 3 groups according to the extent of peripheral area zone of hematoma by IMP-SPECT. There were 10 cases with initial hypoperfusion and complete redistribution (Group I) , 6 with initial perfusion defect and complete redistribution (Group II) , 4 with initial perfusion defect and incomplete redistribution (Group III) . Group III had extensive hematoma compared to Group I. The extent of peripheral area zone of hematoma could be considered as the decreased blood flow area by increased intracerebral pressure and the amplitude of redistribution may be correlated with celler damage. In conclusion, IMP-SPECT was useful to asses the viability of peripheral zone of hematoma. |
