| Abstract | 「要旨」びまん性肝疾患に対し, SPECTにより得た脾肝容積比, 平均脾肝計数比, および蓄積像における肝肺計数比の診断的有用性を検討した. 蓄積像はシンチカメラ下仰臥位の患者に99mTc-phytate 111-222 MBq (3-6 mCi)を肘静脈より急速静注後, 100秒間のデータを加算し, 一画像に表示し, 右下肺野および肝右葉中心部のカウントの比をもって肝肺計数比とした. 肝機能障害例の検出において蓄積像における肝肺計数比は肝疾患の進行度を反映する有用な指標であることが示された. 単位有効肝血流量当たりの肝容積の指標(単位灌流肝容積)として肝容積と蓄積像における肝肺計数比との比をとり, その有用性を検討した. 病因の如何にかかわらず肝疾患の病態の進行とともに単位灌流肝容積が増加することが示された. |

| Abstract | [Summary] It is widely accepted that informations about hepatosplenic volume and blood flow are very important for diagnosis of diffuse hepatic disease and understanding its pathophysiological conditions. Many papers about these topics have already been published, but there are few papers in which both hepatosplenic volume and blood flow are determined in many cases, and the clinical usefulness of these methods has been discussed. The purpose of this paper is to determine the clinical usefulness of the informations about hepatic blood flow estimated by integrated radionuclide images, hepatosplenic volume and spleen to liver count ratio obtained by single photon emission computed tomography (SPECT). In 79 patients with various hepatic diseases, cardiopulmonary circulation and hepatic accumulation of the activity were collected for 100 sec after bolus injection of 111- 222 MBq (3-6 mCi) of 99mTc-phytate, and then integrated as a single image. Liver to lung count ratio (L/P) was estimated by the integrated image. Liver volume (HV), spleen volume (SV) and liver to spleen count ratio (MSC/MHC) were calculated using the data obtained by SPECT. The L/P value was useful as an index of effective hepatic blood flow and showed a high clinical value in evaluating the severity of diffuse liver diseases. |
