Side Effects Of Angiography On The Liver

Angiography is a kind of X-ray projection examination technique in which contrast agent is directly injected into blood vessels to develop the cerebrovascular system. Through angiography, we can specifically understand whether there are malformed blood vessels, whether the blood vessels are unobstructed, whether the blood vessels are narrow and the degree of stenosis, and the morphological changes of the blood vessels, such as the changes in the course, distribution, displacement, thickness and circulation time. Finally, it was determined whether the lesion was caused by the vascular changes or the lesions in other parts of the intracranial, so as to provide the basis for clinical diagnosis and treatment.
