Visceral radiocolloid angiography was performed in 1230 consecutive patients studied with scintigraphy of the reticuloendothelial system (RES). The hepatic arterial flow was considered increased if an early and obviously increased accumulation of the radiocolloid occurred in the liver during the visceral radionuclide angiography, i.e. that the early part of the liver time-activity curve coincided with the early parts of the kidney and spleen time-activity curves with respect to time and steepness. A generalized increase of arterial blood flow to the liver was found in 70 patients, of whom 54 per cent had alcoholic liver disease. 20 per cent metastatic liver disease, 19 per cent had various diagnoses, and in 7 per cent no certain diagnosis was found. Generalized increase of arterial blood flow to the liver gives a typical appearance in radiocolloid angiography and the corresponding time-activity curves. It may be a sign of severe disease, most often localized in the liver, but in some cases it may be of extrahepatic origin. In 27 per cent it was the only obvious pathologic finding. It was in a few cases a reversible condition. Generalized increase of arterial blood flow to the liver is a clinically important finding that could escape detection if radionuclide angiography is not included in the RES scintigraphy.
对1230例连续接受网状内皮系统（RES）闪烁扫描的患者进行了内脏放射性胶体血管造影。如果在内脏放射性核素血管造影期间肝脏中放射性胶体出现早期且明显增加的积聚，即肝脏时间-活性曲线的早期部分在时间和斜率方面与肾脏和脾脏时间-活性曲线的早期部分一致，则认为肝动脉血流增加。在70例患者中发现肝动脉血流普遍增加，其中54%患有酒精性肝病，20%患有转移性肝病，19%有各种诊断结果，7%未发现明确诊断。肝动脉血流普遍增加在放射性胶体血管造影及相应的时间-活性曲线中呈现出典型表现。它可能是严重疾病的一个迹象，最常见于肝脏，但在某些情况下可能源于肝外。在27%的病例中，它是唯一明显的病理发现。在少数情况下，它是一种可逆情况。肝动脉血流普遍增加是一项具有临床重要性的发现，如果RES闪烁扫描中不包括放射性核素血管造影，可能会漏检。
