摘要
目的 评价组织谐波显像 (THI)对诊断门静脉癌栓的应用价值。方法 对 12 8例原发性肝癌患者的 1- 3级门静脉分支分别进行基波显像和THI检查 ,以期发现癌栓存在 ;对照两者在癌栓检出率、边界显示能力和测值等指标的差异。结果 THI在 6 6例中发现门静脉癌栓 ,基波显像检出 4 5例 ,检出率分别是 5 1.5 6 %和 35 .16 % ,两者有显著差异 (P <0 .0 1) ;癌栓边界显示能力THI明显优于基波显像 (P <0 .0 0 5 ) ;两者的测值也有一定差异。结论 THI对门静脉癌栓的较高检出率说明此技术对拓宽超声诊断领域是有价值的 ,可做为基波显像的一个重要补充手段。
Objective: To evaluate the tissue harmonic imaging(THI) diagnosis of cancer embolus in portal vein. Methods In a group of 128 cases with primary liver cancer, fundamental imaging and tissue harmonic imaging were respectively used to find embolus in portal vein; and their diagnosis ratios, embolus margin showing ability and measurement data were statistically compared. Results In 66 cases embolus was picked up by THI, and in 45 cases by fundamental imaging. Their diagnosis ratios had remarkable difference (P<0.01). On embolus margin showing ability, THI is superior to fundamental imaging(P<0.005). Measurement data of embolus size by the two techniques showed difference. Conclusion THI is valuable in expanding the field of ultrasound diagnosis and can be a supplementary means to the conventional fundamental imaging.
