超声造影诊断肝脏多发性病灶

Contrast-enhanced ultrasonography in diagnosis of multiple focal liver lesions

目的探讨超声造影(CEUS)在肝脏多发性病灶中的应用价值。方法对43例肝脏多发性病灶患者(共86个病灶)行CEUS检查,观察其造影增强模式。所有病灶均经病理或增强CT/MRI证实。结果 43例患者中恶性22例,良性21例。恶性患者中,同一患者的2个病灶增强模式不同者10例(10/22,45.45%);良性患者中,同一患者的2个病灶增强模式不同者3例(3/21,14.29%),两组间差异有统计学意义(P<0.05)。结论在肝脏多发性病灶患者中,恶性患者各病灶CEUS增强模式差异较大,而良性患者各病灶的增强模式基本相同。

Objective To explore the diagnostic value of contrast-enhanced ultrasound（CEUS） in patients with multiple focal liver lesions.Methods Fourty-three patients with multiple focal liver lesions underwent CEUS,and the enhancement features of 86 lesions were observed.All the patients were confirmed with histopathology or contrast-enhanced CT/MRI.Results In 43 patients,22 had malignant and 21 had benign liver tumors.Two different enhanced modes in the same patient were observed in 10 patients（10/22,45.45%） with malignant tumors and 3 patients（3/21,14.29%） with benign tumors.There was statistical difference between malignant and benign tumors（P〈0.05）.Conclusion In patients with multiple focal liver lesions,different CEUS enhancement patterns are more obvious in malignant tumors,while the enhancement modes of benign lesions keep basically compatible at the same patient.
