Patient: A week ago, half of the body could not move and speech was slurred. I was given an injection and got better. The hospital asked to do an angiogram, saying there are risks, should I do it? Wu Wei, Department of Neurology, Qilu Hospital, Shandong University: The old man has a plaque in the right common carotid artery, leading to cerebral infarction, and should do a vascular assessment. You can do carotid ultrasound and MRA non-invasive examination first, so that you can decide whether you need to do angiography. Cerebral angiography is now a mature examination technique, and it should not be a big problem for an experienced doctor. I wish the elderly a speedy recovery.
