超声、CT、MRI、PET/CT及PET/MR在结直肠癌肝转移诊治中广泛应用,NCCN指南提出结直肠癌肝转移影像学诊断首选增强MR,但对于每个结直肠癌肝转移患者如何选择合适的影像学检查,充分合理地应用有限的资源是临床关注的重点。结合国内外文献及笔者多年的MDT经验,对于结直肠癌肝转移患者,在参照指南的基础上更要结合患者自身病情,由多学科专家讨论做出合理的影像诊断。

Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography CT (PET/CT) and positron emission tomography MR (PET/MR) are widely used in the diagnosis and treatment of colorectal liver metastases (CRCLM). Contrast-enhanced MR was the first choice in diagnosis of CRCLM by NCCN guidline. But it is important to choose the appropriate imaging modalities for each patient with CRCLM, and rationally use the limited medical resource.Combined with the literature and the authors experience in MDT. On the basis of reference to guidline and combined the patient′s own conditions, it could made reasonable decisions by multidisciplinary experts discussion for patients with liver metastases from colorectal cancer.
