肝脏转移瘤在肝脏恶性肿瘤中居第二位。转移瘤的诊断对于原发灶的诊疗及判断患者的生存率有着重要的帮助,但其早期明确诊断是一个十分棘手的问题。近年来,随着CT灌注成像技术的发展,将功能与形态相结合,由灌注参数和具有不同彩阶的函数图定量分析肝脏的血流动力学改变,能对肿瘤 Liver metastases rank second in liver malignancies. The diagnosis of metastases is of great help to the diagnosis and treatment of primary tumors and the survival rate of patients, but its early diagnosis is a very difficult problem. In recent years, with the development of CT perfusion imaging technology, the combination of function and morphology, quantitative analysis of the hepatic hemodynamic changes by perfusion parameters and function charts with different color scales,
