Comparison of fitted parameters from the two-stage ASL model in tumour tissue and contralateral healthy gray matter.

<p>Box and whisker plots of mean fitted values of (A) cerebral blood flow (CBF), (B) pre-capillary blood volume (f_pc), (C) pre-capillary transit time (pcTT) and (D) bolus arrival time at the capillaries (BAT_c). Data are shown for healthy tissue and tumor regions in all patients, with horizontal lines = group median, box edges = 25th and 75th percentiles, and outliers (+) defined as values larger than q3+1.5*(q3−q1) or smaller than q1−1.5*(q3−q1). Significant difference between groups, determined using a two-tailed paired <i>t</i> test, is indicated by * (p<0.05).
