The aim of this study was to investigate the advantages and disadvantages of JOG technique in pancreatic perfusion computed tomography (CT) imaging.


First, 40 male patients with nonpancreatic diseases, aged 40 to 60 years, were averagely assigned into 2 groups (A and B). Patients in group A and B underwent nonspiral axial perfusion and JOG technique CT scans of the pancreas, respectively. Second, 23 patients with pancreatic masses were randomly assigned into nonspiral axial scan and JOG groups.


There were no significant differences in all perfusion parameters among the pancreatic head, body, and tail within groups (P > 0.05). Perfusion and time to peak of the pancreatic head, body, and tail differed significantly between groups A and B (P < 0.05). There were significant differences in perfusion parameter values between pancreatic carcinoma tissue and normal pericarcinoma tissue in the nonspiral axial scan group. In the JOG group, perfusion and time to peak differed significantly (P < 0.05).


The JOG technique should be cautiously selected on pancreatic perfusion CT scans.
