Background: To optimize the high b values(>200s/mm2)for intravoxel incoherent motion imaging of rectal cancer and to observe the effect of high b values variation on IVIM parameters.Methods:Twenty two patients with rectal adenocarcinoma were included the prospective study.Three groups(A group with all 16 b values: 0,10,20,30,40,60,80,100,150,200,400,800,1000,1200,1500,2000,B group with 14 b values: 0,10,20,30,40,60,80,100,150,200,400,800,1000,1200 and C group with 12 b values: 0,10,20,30,40,60,80,100,150,200,400,800)were selected respectively for measurement by a radiologist(with 10 years of experience in gastrointestinal cancer imaging).
