| Abstract | 「要旨」肝硬変15例を対象に99mTc-in vivo赤血球標識を行い, 腹部のSPECTを施行した. 99mTcO4-は20mCiを静注, SPECTは楕円軌道で360°を64方向から1方向30秒でデータを収集した. 冠状断面像で15例中12例に門脈本幹が描出され, 胃冠状静脈, 脾腎短絡路, 臍静脈などの門脈側副血行路も明瞭に描出された. これら側副血行路の像はScintiphotosplenoportography(SSP)あるいは経動脈性門脈造影像とよく一致した. したがって, 99mTc標識赤血球による腹部SPECTは門脈圧亢進症における門脈側副血行路の非侵襲的な診断法として臨床上きわめて有用と考えられた. 「I. はじめに」Single Photon Emission CT(SPECT)はわが国において現在急速に普及しつつあり, その臨床応用も脳, 心臓, 肝臓などに試みられているが, X線CTに比し空間分解能が劣り, 検査に比較的長時間を要するなどの問題点を有している. |

| Abstract | [Summary]Single photon emission CT (SPECT) was performed for the intra-abdominal blood pool with 99mTc autologous red blood cells (RBC) in 15 patients with liver cirrhosis. Twenty mCi of 99mTc-RBC labeled by in vivo technique were administered intravenously and tomographic imaging of the intra-abdominal vascular blood pool was performed as follows. For each subject, 64 views were obtained over 360° of elliptic rotation at 30 seconds per view using a high resolution low energy parallel-hole collimator. Portal vein and portosystemic collaterals were clearly observed in coronal images. In 12 of 15 patients, portal vein was delineated. Portosystemic collaterals such as coronary vein, splenorenal shunt and umbilical vein were also showed in 12 patients. These images were well consistent with images obtained by scintiphotosplenoportography or arterial portography. Therefore, it is considered that SPECT study for the intra-abdominal blood pool is clinically very useful for the diagnosis of abnormality of portal venous system in portal hypertension. |
