Recurrent atherothrombotic stroke in a 70-year-old male. There is a recent right occipital infarction evident by restricted diffusion in the DWI (b = 1000 s/mm²) (a) with corresponding low signal on the ADC map (b). Higher cuts reveal an old right posterior parietal infarction showing dark signal on the DWI (c) with high signal on the ADC map (d) denoting facilitated diffusion. Time of flight cerebral MRA (maximum intensity projection-MIP) (e) shows diffuse atherosclerotic changes of the cerebral arteries expressed by vessels beading, attenuation, and reduced peripheral branching
