摘　　要：目的探讨射频消融治疗肝脏恶性肿瘤术中超声声像图强回声区对消融范围的预测价值。方法测量50个肝脏恶性肿瘤射频消融过程中超声声像图上强回声的最大横径（D_1），并在相同切面上与术后超声造影无增强区域的最大横径（D_2）比较。结果强回声最大横径与超声造影无增强区域的最大横径高度线性相关，其线性回归方程和相关系数分别为：D_2=0．279＋0．988D_1，r=0．971，P〈0．001，两者的横径具有良好的一致性。结论射频消融术中对强回声的监测有助于预测消融范围，避免损伤邻近重要脏器。Objective To probe the value of hyperechogenic area to predict ablated area during radio-frequency ablation（RFA） of malignant hepatic tumor. Methods The maximum transverse diameter of hypere-chogenicity（D1） on conventional ultrasonogram and the maximum transverse diameter of no-enhanced zone on Contrast-enhanced ultrasonogram（D2） were measured at the same scan plane in 50 with RFA treatment. Results There was high linear relationship between D1 and D2 （r=0.971,P〈0.001）. The regression equation was D2=0.279＋ 0.988 D1.The D1 and D2 were considered highly consistent. Conclusion The monitoring of the hyperechogenicity during RFA in patients with malignant hepatic tumors can predict the coagulation area and might be helpful to prevent the ablation of adjacent organs and vessels.
