【摘要】：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(χ~2=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,P0.001)。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。
[Abstract]:Objective to evaluate the value of CDFI and SMI in ultrasound imaging of gastric cancer. Methods the CDFI and SMI data of 69 patients with gastric cancer confirmed by pathology were analyzed retrospectively. The positive rate of blood flow signal between CDFI and SMI was compared. The thickness of gastric cancer with blood flow signal, Results the positive rate of CDFI showed that the positive rate of blood flow signal was 95.6566 / 69. The difference was statistically significant (蠂 ~ 2 / 11.461 / P ~ (0.001)). CDFI was 19.92 卤4.54 mm ~ (-1) and the difference was significant (P ~ (0.043)) and CDFI (P ~ (0.043)) and CDFI were significantly higher than those in control group (P = 2.048 ~ 0.043, P = 0.043.CDFI = 19.92 卤4.54 mm / min, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043, P = 0.043). There was significant difference in blood flow signal grading by SMI. Conclusion SMI is more sensitive to low flow velocity microvascular blood flow signal in gastric cancer focus than that of CDFI. It can provide important reference information for clinic.
