What is the purpose of the angiography needle?

The purpose of angiography examination is to better diagnose the organs that need to be examined, so that the size, shape and internal structure of the examined organs can be more clearly reflected, so as to achieve the purpose of diagnosis. Coronary angiography can show and understand whether there is stenosis inside the coronary vessels, the degree of stenosis, the condition of the vessel wall and the size of the lesion through contrast media.

At present, coronary angiography is considered as the golden index in the diagnosis of coronary heart disease. Contrast-occupying lesions can be clearly diagnosed by the third phase change of contrast media by contrast-enhanced ultrasound and CT. At present, angiography examination is more and more widely used in clinic, which can be applied to various organs of the body, including the heart, blood vessels, abdominal organs, reproductive system, eyes, brain and so on.
