Contrast enhancement pattern, quantitative analysis parameters were observed and compared between intravenous and percutaneous CEUS.

观察两组淋巴结经静脉和经皮造影的增强模式，分析峰值强度等定量分析参数的差异。

In 6 patients (10%), the arterial contrast enhancement pattern could not be determined because of the very small size of the lesions or fibrotic nodules.

在6例(10%)病人中，由于病变很小或纤维结节的原因，动脉期增强模式不能确定。

The parameters for evaluation in dynamic contrast enhanced MRI included early enhancement rate, time signal intensity curve pattern and lesion's morphological features.

动态资料的评价参数包括：早期增强率、时间信号强度曲线类型以及病变的形态学特征。
