Initially, ROIs were drawn on the MIP images, on the solid part of tumour, trying to exclude areas with necrosis or vessels. The ROIs were then automatically copied onto the perfusion maps and corresponding CBV, CBF and K Trans values were acquired. For every patient, reference ROIs were also drawn on the healthy contralateral hemisphere and perfusion parameters were obtained as control values.","tracks":[]}
