The authors describe a technique for visualizing and quantitating blood flow and cardiac dynamics following the intravenous administration of contrast material (less than 1 ml/kg). This method uses a digital radiographic device while motion by the patient or test subject is stopped. Preliminary flow studies of the carotid arteries and heart of a dog are presented. This technique has the potential to quantitate physiological parameters such as relative blood flow through pairs of arteries, cardiac output, regional ejection fraction, and heart-wall movement and thickening.
作者描述了一种在静脉注射造影剂（小于1毫升/千克）后可视化和定量血流及心脏动力学的技术。该方法在患者或受试对象停止运动时使用数字射线照相设备。文中展示了对一只狗的颈动脉和心脏的初步血流研究。这种技术有潜力对生理参数进行定量，如通过成对动脉的相对血流、心输出量、局部射血分数以及心脏壁的运动和增厚情况。
