Conventional imaging modalities are presently recommended for the detection of liver metastases. However, the presence of liver micrometastases is a major diagnostic problem. It has been known that micrometastases could be associated with changes in the liver blood flow.
We examined several parameters by color Doppler ultrasound to estimate hepatic artery flow in 30 patients without and 17 patients with liver metastases from colon cancer.
Mean values of hepatic artery diameter (4.25 + or - 0.81 mm in patients with liver metastases were not statistically different from those in patients without metastases (3.98 + or - 0.81). Patients with liver metastasis had significantly higher (p=0.007) mean values of systolic speed (61.33 + or - 30.01 cm/s) in comparison to patients without metastasis (41.38 + or - 16 cm/s).
Based on these results we suggest that color Doppler examination can be an additional quick noninvasive method in the detection of circulatory changes in the estimation of liver metastases.
目前推荐使用传统成像方式来检测肝转移。然而，肝微转移的存在是一个主要的诊断难题。已知微转移可能与肝脏血流变化有关。
我们通过彩色多普勒超声检查了几个参数，以评估30例无结肠癌肝转移患者和17例有结肠癌肝转移患者的肝动脉血流。
肝转移患者的肝动脉直径平均值（4.25±0.81毫米）与无转移患者（3.98±0.81）相比，无统计学差异。与无转移患者（41.38±16厘米/秒）相比，肝转移患者的收缩期速度平均值（61.33±30.01厘米/秒）显著更高（p = 0.007）。
基于这些结果，我们认为彩色多普勒检查可以作为一种额外的快速非侵入性方法，用于在评估肝转移时检测循环变化。
