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 1 2 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 1例中发现门静脉癌栓 ,基波显像检出 4 9例 ,检出率分别是 4 7.7%和 38.3% ,两者有显著差异 (P<0 .0 5 ) ;癌栓边界显示能力 THI明显优于基波显像 (P<0 .0 5 ) ;两者的测值也有一定差异(P<0 .1 0 )。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 value of tissue harmonic imaging (THI) in the diagnosis of portal vein tumor thrombus. Methods: Radionuclide imaging and THI were performed on the 1 ~ 3 portal vein branches of 128 patients with primary liver cancer in order to find the existence of tumor embolus: the control both in the detection rate of tumor thrombus, the border display ability and measurement Value and other indicators of the difference. Results: The thrombosis of portal vein was found in 61 cases of THP. Forty-nine cases were detected by fundamental imaging with the detection rates of 4 7.7% and 38.3%, respectively, which were significantly different between the two groups (P <0.05). The thrombus boundary display ability THI was significantly better than the fundamental imaging (P <0. 05); There was also some difference between the two measurements (P <0.01). Conclusion: The high detection rate of thrombosis in portal vein by THI indicates that this technique is valuable in the field of ultrasonic diagnosis and can be used as an important supplementary means of fundamental imaging
