This study was performed to identify the normal anatomic orientation of pulmonary arteries and to obtain the normal baseline parameters and the optimal contrast material delivery methods of computed tomographic pulmonary angiography (CTPA) on normal beagle dogs. Based on the contrast injection flow rate, the contrast volume, and the administration methods, the experimental groups were divided into 4 groups such as group 1 : 2 ml/s, 3 ml/㎏, and monophasic administration; group 2 : 5 ml/s, 3 ml/㎏, and monophasic administration; group 3 : 5 ml/s, 4 ml/㎏, and monophasic administration; group 4 : 5 ml/s and 2 ml/㎏ in first phase, 0.3 ml/s and 2 ml/㎏ in second phase, as biphasic administration.
