明确有无门脉系分流,并使之定量化,对估计门脉高压的病理和预后甚为重要。作者将用于脑血流闪烁扫描的~(131)I-碘苯异丙胺(以下简IMP)作直肠给药法测定肝和肺的放射性,建立一种能够定量地测定门脉系分流的新方法。检查方法:禁食4小时以上,灌肠后取左侧卧位插入20 Fr导尿管至距肛20 cm处,注入IMP 1.3 mCi后使仰卧位,用大视野闪烁扫描机观察胸腹部扫描象 Clear portal vein shunt, and to quantify, to estimate the pathology and prognosis of portal hypertension is very important. The authors used ~ (131) I-iodine isopropylamine (hereinafter abbreviated IMP) for cerebral blood flow scintigraphy to determine the radioactivity in the liver and lung for rectal administration to establish a new assay capable of quantitatively measuring portal venous shunts method. Inspection methods: fasting more than 4 hours after the enema take the left lateral position into the 20 Fr catheter to the anus 20 cm from the IMP IMP 1.3 mCi into the supine position, with a large field scintilloscope scan chest and abdomen scanning
