| Abstract | 「要旨」99mTc標識心筋血流製剤である99mTc-Tetrofosminを用いたSPECTにおいて, 180度データ収集と360度データ収集を比較した. 虚血性心疾患が疑われた8例で運動負荷時と安静時の検査を別の日に行った計16回の検査において, 180度収集(32方向, 1方向30秒)と360度収集(64方向, 1方向15秒)の両方を行い, 画質と診断の一致度を検討した. 画質に関しては, 16検査中14検査で180度収集による画像の方が鮮明と判定され, 360度収集の像の方が鮮明と判定された例はなかった. 診断は128領域中123領域(96.1%)で一致したが, 5領域では360度収集で病変を過小評価する傾向があった. 99mTc-Tetrofosminによる心筋シンチグラフィにおいて, 180度データ収集の方が鮮明な画像が得られ, 病変の描出も良好である可能性が考えられた. |

| Abstract | [Summary]We compared 360°data collection technique with 180°technique in SPECT using a new myocardial perfusion imaging agent, 99mTc-Tetrofosmin. Eight patients were examined at stress and at rest on separate days. Following the injection of 555 MBq 99mTc-Tetrofosmin, 64 views of 15 sec each were collected during a 360°rotation, and 32 views of 30 sec each during a 180°rotation. The 180°data collection provided superior images in sharpness in 14 of 16 scans. The interpretation was concordant in 123 of 128 regions (96.1%), and hypoperfusion was considered to be underestimated in 5 regions using the 360°technique. It was suggested that the 180°data collection technique is more effective in myocardial SPECT employing 99mTc-Tetrofosmin than the 360°technique. |
