Arteriography abnormalities

Arteriography is an examination method in which arteries are filled with a contrast agent and the arterial system is visualized. The distribution, number, and shape of the human arterial system are relatively constant. The angiographic examination is mainly an angiographic examination. In order to obtain the optimal display of the artery to be examined, it is desirable to introduce the catheter as close as possible to the artery of interest, and the local concentration can be as high as possible after injection of the contrast agent. According to the position of the catheter tip from the vessel of interest, it can be divided into non-selective angiography, selective angiography and super-selective angiography.
