Patient with progressive disease. a) Post-contrast T1-weighted turbo-FLASH. Source image shows the region of interest (ROI) drawn around the tumor, AATH-calculated kep parametric map (1/min) from b) pre-treatment c) intra-treatment and d) post-treatment study are shown. At intra-treatment study, tumor showed an increase in kep as well as in size. At the post-treatment study, a decrease in kep and a slight increase in tumor size is seen. Significant heterogeneity of the tumor can be observed
