Fig. 13From: Advanced imaging of colorectal cancer: From anatomy to molecular imagingTumour hypoxia. BOLD images (fusion of T2 and T2*) pre- and following the administration of oxygen may demonstrate a mucinous adenocarcinoma of the rectum. In basal conditions, the tumour showed high signal on T2* map. After O2 administration, the signal decreased with an ascending curve of ΔR2* (red line), which is related to tumour radioresistanceBack to article page
