Arteriography

X-ray inspection method. An inspection method in which the arterial system is developed by injecting the contrast agent directly into the artery (manual injection or high-pressure syringe) to fill the artery with contrast agent. 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 best 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 superselective angiography. Since the advent of DSA (digital subtraction angiography), most arterial angiography can be performed by DSA. B-type and Doppler-type ultrasound, CT, and MRI can also be used more and more to show the arterial system, but in the foreseeable future, these tests cannot replace arteriography. Arterial angiography requires an arterial intubation and is invasive.
