Fig. 4From: Association between high-resolution MRI-detected extramural vascular invasion and tumour microcirculation estimated by dynamic contrast-enhanced MRI in rectal cancer: preliminary resultsBoxplots showed the relationships between mrEMVI status and kep (a) and ve (b) values. Lower kep values were noted among mrEMVI-positive patients than in mrEMVI-negative patients, while ve values in the mrEMVI-positive group were significantly higher than those in the mrEMVI-negative groupBack to article page
