JOG Technique Versus Nonspiral Axial Scan in Pancreatic Perfusion Computed Tomography Imaging and Their Preliminary

Objective:
The aim of this study was to investigate the advantages and disadvantages of JOG technique in pancreatic perfusion computed tomography (CT) imaging.
Methods:
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.
Results:
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).
Conclusions:
The JOG technique should be cautiously selected on pancreatic perfusion CT scans.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
