Colorectal cancer is a major cause of cancer death in Western Europe and United States; the liver is the most common site for colorectal metastases. PET has an important role in the management of patients with colorectal liver metastases. It is an effective tool to detect hepatic metastases and to monitor the response to systemic and local therapy. The major impact of PET-CT over PET alone is the improvement in the certainty of lesion location. PET-CT has the unique advantage to combine functional and anatomic imaging in an integrated scanner; it allows a thoroughly evaluation of patients with colorectal liver metastases.
结直肠癌是西欧和美国癌症死亡的主要原因；肝脏是结直肠癌转移最常见的部位。正电子发射断层显像（PET）在结直肠癌肝转移患者的管理中发挥着重要作用。它是检测肝转移和监测全身及局部治疗反应的有效工具。PET-CT相较于单独的PET的主要优势在于提高了病变定位的准确性。PET-CT具有在一台集成扫描仪中结合功能成像和解剖成像的独特优势；它能够对结直肠癌肝转移患者进行全面评估。
