Angiography of cerebral vessels
This method is a visualization diagnosis of blood vessels of the brain with a low dose of X-ray exposure through cerebral angiography, as well as cervical vessels supplying blood to the brain. Cerebral angiography is used, if there is a suspicion for brain tumor, cerebral hemorrhage or other vascular disease. In the neck, before a possible surgical intervention, the stenoses of the brachiocephalic artery and subclavian artery, as well as the carotid and vertebral arteries, are visualized.
Angiography of the lower extremities vessels
If vessels are being examined of the lower extremities and pelvis within magnetic resonance angiography, possible stenoses or vascular ruptures should be identified. This method is used, for example, in diabetics or when there is a suspicion of the presence of the pathology of the vessels of the lower limbs and pelvis.
Risks associated with MR-angiography
With MR angiography, a relatively small number of complications occur. The most common possible complications include the sensation of heat and unpleasant taste in the mouth that may occur during the injection of contrast medium.
Hypersensitivity to contrast agent or even an allergic reaction is manifested only in rare cases. However, during the preparation for the study, the doctor should ask the patient about the presence of kidney failure. If the patient responds positively, it may be necessary to avoid using contrast media.
