| 目的 通过比较彩色多普勒血流成像(CDFI)和超声造影成像技术(CEUS)对食管静脉曲张(EV)和胃底静脉曲张(GV)血流信号的显示,探讨CEUS在食管胃底静脉曲张(EGV)诊断中的应用价值。方法 在B型超声检查基础上,对23例EGV患者先后行CDFI和CEUS检查,比较二者对EV和GV血流信号的显示率。结果 CDFI和CEUS对EV的血流信号显示率分别为42.11%(8/19)、73.68%(14/19),对GV的血流信号显示率分别为76.47%(13/17)、94.12%(16/17)。CEUS对EV的血流信号显示效果明显优于CDFI(χ2=4.17,P＜0.05),二者对GV的血流信号显示差异无统计学意义(χ2=1.33,P＞0.05)。结论 CEUS可弥补CDFI对EGV血流信号检出的不足,明显提高EV的血流信号检出率。 |

| Objective To explore the value of contrast-enhanced ultrasonography (CEUS) in diagnosis of esophagogastric varices (EGV) compared with color Doppler flow imaging (CDFI). Methods CDFI and CEUS were performed on 23 variceal patients based on the B mode ultrasound examination. The blood flow of esophageal varices (EV) or gastric varices (GV) displayed with CDFI and CEUS were compared. Results The flow signal demonstration rate of EV with CDFI and CEUS was 42.11% (8/19) and 73.68% (14/19), while that of GV with CDFI and CEUS was 76.47% (13/17) and 94.12% (16/17), respectively. CEUS displayed the flow signal of EV better than CDFI did (χ2=4.17, P＜0.05), but the flow signal demonstration rate of GV was not significantly different (χ2=1.33, P＞0.05). Conclusion CEUS can be used more extensively in clinic practice for diagnosis of EGV. |
