| 摘 要： | 目的探讨低机械指数谐波超声造影在肝脏局灶性病变良、恶性诊断的价值。方法对2004年3月～2005年1月129例超声检测的局灶性肝脏病变患者进行低机械指数灰阶超声造影、增强MR／CT和／或病理检查。结果低机械指数谐波超声造影对恶性病变诊断的的敏感性、特异性和准确性分别为96％、90．7％和93．8％。结论超声造影可较好地鉴别良恶性局灶性肝脏病变。

| Abstract: | Objective To investigate the clinical merit of contrast-enhanced harmonic ultrasonography with low mechanical index in the differential diagnosis of focal liver lesions (FLL). Methods From March 2004 to January 2005, one hundred and twenty-nine patients with FLL were examined by CEHU, contrast-enhanced CT/MR and/or pathology. Results The sensitivity, specificity and accuracy of diagnosing malignant liver tumors by contrast-enhanced harmonic ultrasonography with low mechanical index were 96%?90.7%?93.8% respectively. Conclusions Contrast-enhanced harmonic ultrasonography with low mechanical index is helpful for differentiating benign from malignant focal liver lesions. |
