估价肝转移存在与否,对许多恶性肿瘤的分期很重要。因肝体积大和难易达到定位,准确测定肝肿瘤的累及仍是一个困难的临床问题。本研究系前瞻方式比较不用对比剂CT(NC—CT),用水溶对比剂CT(WSC—CT)和用乙碘油乳剂CT(EOE—CT)检测肝转移的可靠性。
Estimating the presence or absence of liver metastases is important for the staging of many malignancies. Due to the large volume and difficulty in liver positioning, accurate determination of the involvement of liver tumors remains a difficult clinical problem. This study is a prospective way to compare the reliability of liver metastasis without contrast agent CT (NC-CT), water soluble contrast agent CT (WSC-CT) and the use of ethyl acetate oil emulsion CT (EOE-CT).
