Cerebral blood supply insufficiency check which several items

Cerebral artery insufficiency is mainly due to insufficient cerebral blood flow caused by cerebral artery stenosis, and then caused by neurological dysfunction. The common cause of cerebral artery stenosis is atherosclerosis of the arterial wall. Therefore, when checking blood for cerebral artery insufficiency, the focus is on the risk factors of cerebral atherosclerosis, such as blood lipids, blood sugar, cholesterol, etc. Then, CT or magnetic resonance imaging, or even CT and magnetic resonance angiography of cerebral vessels, that is, CTA or MRA, is often done for imaging examination. If the stenosis is found to be serious, DSA may be further required, that is, a minimally invasive operation is performed in the intervention room to see if the cerebral artery is not narrowed, to what extent the stenosis is, and whether the compensation of cerebral vessels is good or not.
