Abstract：Objective To evaluate the clinical value of CT perfusion orbital subtraction imaging in the treatment of primary
hepatocellular carcinoma after transcatheter arterial chemoembolization (TACE). Methods A total of 98 patients with primary
liver cancer who underwent TACE were successfully followed up in our hospital from January 2013 to June 2017. Liver dynamic
enhancement MRI scan and 320-row volume CT perfusion scan were performed one month after surgery, and CT orbital subtraction
imaging were used to obtain CT subtraction images. The interval between the two examinations was less than one week. Two
imaging methods were evaluated to determine the consistency of the residual area of the residual arterial phase. Results The two
imaging methods had a good agreement on the determination of the residual enhancement zone (Kappa=0.5) and the measurement
of the maximum diameter of the tumor in the arterial phase (t=1.895，P=0.068), and the measurement of the shortest diameter of
the tumor arterial phase was statistically different (t=2.298, P=0.033). Conclusion CT perfusion orbital subtraction technique can
effectively evaluate the tumor residual tissue and its enhancement after TACE, and it has certain clinical value for guiding follow-up
treatment.
