| Abstract | 「要旨」 N-isopropyl-p-[123I]iodoamphetamineによる脳血流シンチグラフィを脳血管障害患者14例に対し施行した. 123I-IMP静注と同時に高感度コリメータを装着した島津製リング型ECTを用いて, 1フレーム 2スライス2分スキャンを15〜20回行い, 初期dynamic imageとした. これと, 静注30分後より回転型ECTを用いて撮像したearly imageの123I-IMP分布状態を比較し, delayed imageを参考に両者のdiscrepancy の有無を検討した. 初期dynamic imageで血流低下部位が存在するが, early imageでは血流低下部位が認められなくなったものが, 14例中2例あった. 軽度の血流低下部位の描出には初期dynamic imageが有用であることが示唆された. |

| Abstract | [Summary] N-isopropyl-p-[123I]iodoamphetamine (IMP) SPECT was done in 14 patients with cerebrovascular disease. Immediately after injection of 3 mCi IMP, sequential 2 minutes SPECT images (dynamic images) were obtained for 15 minutes using a circular detector array emission tomographic system (Shimadzu SET-030W) . Then standard SPECT images were obtained at 30 minutes (early images) and 5 hours (delayed images) using a rotating scintillation camera ECT system (GCA-601E, Toshiba) . Two patients out of 14 studies showed discrepancy of the findings between dynamic images and early images ; dynamic images revealed low uptake area though early images showed no defect. Possible mechanism of this phenomenon might be due to so called redistribution phenomenon occured during obtaining early images. In conclusion, early dynamic images is useful in cases with slightly decreased cerebral blood flow. |
