Despite these concerns, careful selection of sequences ensures that multiparametric MRI is well tolerated and widely used in acute stroke, and is the investigation of first choice in many stroke centres worldwide. 88 Nonetheless, given the large body of circumstantial evidence, best medical management for stroke includes advice on diet, exercise, smoking and alcohol use.

89 Surgery is most efficient when not delayed too long the risk of recurrent stroke in a patient who has a 50 or greater stenosis is up to 20 after 5 years, but endarterectomy reduces this risk to around. This position for tPA is based upon the findings of two studies by one group of investigators 146 which showed that tPA improves the chances for a good neurological outcome.
