Whether it is cerebral hemorrhage or cerebral ischemia (cerebral infarction, cerebral transient ischemic attack), the root cause is a problem with cerebral blood vessels, which are like underground water pipes. If you want to diagnose the cause of the disease, blind treatment may aggravate the patient’s condition or delay the best time for treatment. A whole brain angiogram is the best choice for a definitive diagnosis. Whole brain angiography can show detailed images of all large blood vessels and capillaries from the heart and to the neck and brain, and it is also dynamic and fluid with blood flow, and it can also be seen all around like looking at fruits on a tree, forming a three-dimensional image of blood vessels. We can image the blood vessels of the neck, brain and face in detail. This guides the interventional or surgical treatment of vascular diseases of the head and neck.
