Abstract:
Objective To evaluate the application value of superb micro-vascular imaging (SMI) technology in gastric cancer.Methods Data of color Doppler flow imaging (CDFI) and SMI of 69 patients with gastric cancer confirmed by pathology were analyzed retrospectively.The positive rate in displaying the blood flow,the thickness of gastric carcer lesion with blood flow signal and the grade of blood flow obtained with CDFI and SMI were compared.Results The positive rate of blood flow was 75.36％ (52/69) of CDFI and 95.65％ (66/69) of SMI,respectively.The difference of positive rate between the two methods was statistically significant (x2 =11.461,P=0.001).The thickness of gastric cancer lesion with blood flow signal measured with CDFI was (19.92±4.54)mm,and that measured with SMI was (16.92±5.77)mm (t=2.048,P=0.043).There was statistical difference of the grades of blood flow between SMI and CDFI (Z=5.354,P＜ 0.001).Conclusion SMI technology is more sensitive for the low flow velocity of micro vessels signal in gastric carcinomas compared with CDFI,which can provide valuable reference for clinic.
