超声造影对结直肠癌肝转移与原发性肝癌的鉴别诊断

Application of Contrast-Enhanced Ultrasonography in the Differential Diagnosis of Hepatic Metastasis of Colorectal Cancer and Primary Hepatic Carcinoma

目的:探讨超声造影对结直肠癌肝转移与原发性肝癌的鉴别诊断要点。方法:对结直肠癌肝转移与原发性肝癌患者各30例进行超声造影检查,并对超声检查过程进行定性和定量分析。结果:原发性肝癌组典型增强形态为病灶整体均匀增强,结直肠癌肝转移组的典型增强形态为病灶周边厚环状增强。两组患者的峰值增强强度和50%清除斜率的差异有统计学意义。结论:超声造影检查能对结直肠癌肝转移与原发性肝癌患者进行鉴别诊断,有一定的临床应用价值。

Objective： To evaluate the real time contrast-enhanced ultrasonography （CEUS） in the differential diagnosis of hepatic metastasis of colorectal cancer and primary hepatic carcinoma. Methods： Thirty cases of primary hepatic carcinoma and 30 cases of hepatic metastasis of colorectal cancer were examined with CEUS. Results： There were significant differences in CEUS images and parameters, such as peak enhancement intensity and wash-out 50% slope, between the two groups. Conclusion： CEUS is valuable in the differential diagnosis of primary hepatic carcinoma from hepatic metastasis of colorectal cancer.
