【摘要】：目的探討超微血管成像(SMI)技術(shù)在胃癌超聲成像中的應(yīng)用價(jià)值。方法對(duì)69例經(jīng)病理證實(shí)的胃癌患者的CDFI及SMI資料進(jìn)行回顧性分析。比較CDFI與SMI顯示血流信號(hào)陽(yáng)性率、有血流信號(hào)的胃癌病灶厚度、血流信號(hào)分級(jí)的差異。結(jié)果 CDFI顯示血流信號(hào)的陽(yáng)性率為75.36%(52/69),SMI陽(yáng)性率為95.65%(66/69),差異有統(tǒng)計(jì)學(xué)意義(χ~2=11.461,P=0.001)。CDFI測(cè)量有血流信號(hào)的胃癌病灶厚度為(19.92±4.54)mm,SMI所測(cè)為(16.92±5.77)mm,差異有統(tǒng)計(jì)學(xué)意義(t=2.048,P=0.043)。CDFI與SMI顯示血流信號(hào)分級(jí)差異有統(tǒng)計(jì)學(xué)意義(Z=5.354,P0.001)。結(jié)論 SMI技術(shù)對(duì)胃癌病灶低流速微小血管血流信號(hào)較CDFI更敏感,可為臨床提供重要的參考信息。
[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 鹵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 鹵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.
