BACKGROUND AND PURPOSE Various calculation methods are available to estimate the transit-time on MR perfusion-weighted imaging (PWI). Each method may affect the results of PWI. Steno-occlusive disease in the parent vessels is another factor that may affect the results of the PWI. The purpose of this study was to elucidate the effect of the calculation methods and underlying vasculopathy on PWI. METHODS From a pool of 113 patients who had undergone PWI during the study period, a total of 12… CONTINUE READING
