| 目的 探讨超微血管成像（SMI）技术在胃癌超声成像中的应用价值。方法 对69例经病理证实的胃癌患者的CDFI及SMI资料进行回顾性分析。比较CDFI与SMI显示血流信号阳性率、有血流信号的胃癌病灶厚度、血流信号分级的差异。结果 CDFI显示血流信号的阳性率为75.36%（52/69），SMI阳性率为95.65%（66/69），差异有统计学意义（χ2=11.461，P=0.001）。CDFI测量有血流信号的胃癌病灶厚度为（19.92±4.54）mm，SMI所测为（16.92±5.77）mm，差异有统计学意义（t=2.048，P=0.043）。CDFI与SMI显示血流信号分级差异有统计学意义（Z=5.354，P<0.001）。结论 SMI技术对胃癌病灶低流速微小血管血流信号较CDFI更敏感，可为临床提供重要的参考信息。 |

| 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 (χ2=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. |
