Incidence of Postangiographic Abnormalities Revealed by Diffusion-Weighted MR Imaging AJNR 21:55-59, Britt,P.M.,et al, 2000 See this aricle in Pubmed Article Abstract Neither clinical signs nor abnormalities on DW-MR images were found, which suggested no infarction after angiography in our patient sample. Based on this data, an upper bound of 9% (95% confidence) is predicted for the appearance of abno rmalities revealed by DW-MR imaging after cerebral angiography. Cerebral angiography is associated with an incidence of asymptomatic cerebral infarction of nor more than 9%. It well may be substantially lower than this estimate; a more accurate evaluati on of the true incidence would require a significantly larger study population. This test provides a convenient noninvasive means of assessing procedure-related cerebral infarction, such as that which occurs after carotid endarterectomy or vascular angio plasty and stenting.
