WebDWI is the first sequence to show pathology, and can demonstrate hyperintensity in the affected areas within hours of the inciting event. Increased T2-signal can typically be seen after approximately 24 hours in the early subacute phase. 7 This is due to increased edema in the injured gray matter structures. Acute Hypertensive Encephalopathy WebThe hyperintensity on T2-weighted imaging supposedly results from an abnormal myelin signal [ 1 ]. Increased signal on diffusion-weighted sequences may be seen with normal, decreased, or elevated ADC values within the basal ganglia and pons and is most consistent with myelin destruction [ 9, 10] ( Fig. 2C ).
