摘要
目的 探讨B Flow技术在下肢静脉曲张症中的应用价值。方法 应用B Flow显像技术、彩色血流显像 (CDFI)和血流功率图 (PDI) ,对 33例 (4 4条下肢静脉 )经临床及X线造影确诊为下肢静脉曲张症的患者 ,进行术前超声血流动力学检测。结果 B Flow技术结合CDFI或PDI、频谱可明确病因和范围、严重程度。结论 B Flow有更高帧频、高分辨力和全景显示功能。为下肢静脉曲张症提供可靠的病因、定位诊断和半定量诊断 。
Purpose To evaluate the value in varicosis of lower limb (VLL) by B Flow. Methods 33 cases with VLL diagnosed by angiography were observed by B Flow and CDFI. Dynamics of blood flow were detected pre operation. Results The causes of the disease and range involved could be defined combined with CDFI or PDI. The degrees of the venous lesion may be classified . Conclusion B Flow has more functions of high frame rate, high dynamic range and bandwidth. B Flow can provide effective evidences of the disease, the locating diagnosis and semi quantificational diagnosis.
