动脉注射CO2与数字减影荧光透视相结合，在17例患者中始终产生了临床有用的动脉图像。偶尔也获得良好的实质图像和静脉造影。气体的浮力要求感兴趣区域处于非依赖位置，以确保良好的动脉灌注。气体的极低粘度应允许通过微导管输送CO2，这将降低动脉损伤的风险。CO2不会产生超敏反应，即使是大体积，也不会产生碘化造影剂相关的不适。
Arterially injected CO2 coupled with digital subtraction fluoroscopy consistently produced clinically useful images of arteries in 17 patients. Occasionally good parenchymal images and venograms were also obtained. The buoyancy of the gas requires that the area of interest be in a nondependent position to insure good arterial perfusion. The exceedingly low viscosity of gas should permit delivery of the CO2 via microcatheters which would lessen the risk of arterial injury. CO2 does not produce hypersensitivity reactions and, even in large volumes, should not produce the discomfort associated with iodinated contrast material.
