目的探讨B-flow超声显像技术对肝脏肿瘤鉴别诊断的价值。方法对43例共61个肝脏肿瘤分别进行彩色多普勒血流显像、B-flow超声显像以及脉冲多普勒血流分析,其中原发性肝脏恶性肿瘤18例,转移性肝肿瘤11例,肝血管瘤14例。肝脏恶性肿瘤病例经手术病理证实,肝血管瘤病例经手术病理或临床确诊。结果 B-flow技术对肝脏肿瘤内血流检出率(90%,55/61)明显高于彩色多普勒血流显像(54%,33/61),肝脏恶性肿瘤的平均RI明显高于肝血管瘤(P<0.001)。如果以B-flow联合多普勒超声测及血流,且RI≥0.6作为诊断肝脏恶性肿瘤的指标,则敏感性为79.5%,特异性为86.7%。结论 B-flow技术在肝脏肿瘤的鉴别诊断中有一定的临床实用价值。
Objective to investigate differential diagnosis value of B-flow ultrasound imaging for liver tumor.Methods carry on color Doppler flow imaging, B-flow ultrasound imaging and pulse Doppler blood-flow analysis for 43 cases 61 liver tumors, and there were 18 cases primary liver malignant tumor, 11 cases metastatic liver tumor, 14 cases hepatic hemangioma. Liver malignant tumor cases were confirmed by operation pathology, and hepatic hemangioma cases were confirmed by operation pathology or clinical diagnosis. Results detection rate of B-flow technique for liver tumor blood flow (90%, 55/61) was significantly higher than color Doppler flow imaging (54%, 33/61), and average RI of hepatocellular carcinoma was significantly higher than hepatic hemangioma (P<0.001). If detect blood flow with B-flow combined with Doppler ultrasound, and RI≥0.6 were diagnosis index for malignant liver tumor, sensitivity was 79.5%, specificity was 86.7%.Conclusion B-flow technology has some certain clinical value in differential diagnosis of liver tumors.
