Purpose:To investigate the value of contrast-enhancement boost(CE-Boost)technique based on abdominal enhanced CT in improving the image quality of blood supply vessels for gastric cancer.Methods:Seventy-three patients with gastric cancer who underwent abdominal enhanced CT were collected prospectively.Flexible subtraction was performed on plain and enhanced arterial phase thin-slice images(group A)to obtain CE-Boost sequence images(group B).The CT value and image noise(SD)of the proximal segment of left gastric artery and the erector spine muscle were measured,and the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.The number of left gastric artery branches displayed in the two groups of images was counted,and the two groups of images were subjectively scored.Results:Compared with group A,the CT value,CNR and SNR of blood supply vessels of gastric cancer were significantly increased in group B(P＜0.001).There was no significant difference in SD value(P=0.068).Compared with group A,the CT value was higher and the SD value was decreased in group B,and the differences were with statistical significance.The number of left gastric artery branches in group B was more than that in group A(Z=-7.47,P＜0.001),and the subjective score in group was significantly higher than that in group A(Z=-10.12,P＜0.001).Conclusion:The blood supply vessels of gastric cancer can be optimally displayed by CE-Boost technology,which provides more accurate basis for surgical plans.
