摘　　要：目的探讨超声造影在不典型肝转移癌诊断中的应用价值。方法对59例不典型肝转移癌病灶进行常规超声（二维、彩色多普勒超声）和超声造影（CEUS）检查，观察转移癌造影剂灌注特征，比较造影前后超声诊断的准确性。结果CEUS较常规超声显示不典型肝转移癌血流的病灶数目增多（P〈0．05），血流灌注、增强类型复杂多样。CEUS和常规超声对不典型肝转移癌的诊断正确率分别为83％、37％。超声造影诊断的准确率显著提高（P〈0．05）。超声造影显示病灶最大径测值、新病灶数较常规超声增多。结论超声造影对不典型肝转移癌具有重要的诊断价值。Objective To evaluate the value of contrast - enhanced ultrasound （CEUS） in atypical metastatic liver tumors. Methods Fivty - nine patients with atypical metastatic liver tumors were studied both by conventional techniques and CEUS. The enhancement of echogenicity was evaluated. The diagnosis obtained by means of surgical biopsy. Results After CEUS, the number of flow lesions was significantly more than before CEUS（ P 〈 0.05 ）. The enhancement types of metastatic liver tumors were various, scarcing specificity compared with pathologic cell types of the primary tumors. The true diagnosis in CEUS and conventional ultrasound were 83% and 37% retrospectively. The increase in correct diagnosis was significiant（ P 〈 0.05 ） when conventional ul- trasound was tested against CEUS. The size and number of the lesions increased on CEUS compared with conventional ultrasound. Conclusions CEUS plays an important role in dignosis of atypical metastatic liver tumors.
