Rapid advances in imaging technology have improved the detection, characterization and staging of colorectal liver metastases. Multi-modality imaging approach is usually the more useful in staging colorectal liver metastases. Multi-detector computed tomography (MDCT) remains the main imaging modality for preoperative planning, lesion detection and tumour surveillance. Magnetic resonance imaging (MRI) and contrast enhanced ultrasonography (US) are invaluable in problem solving for characterization indeterminate lesions, while contrast enhanced intra-operative ultrasound (CE-IOUS) may be the new gold standard staging tool prior to liver resection. Ultimately, the imaging strategy has to be tailored to the clinical situation to obtain the most relevant information for optimal use of available imaging resources.
成像技术的快速发展改善了结直肠癌肝转移的检测、特征描述和分期。多模态成像方法通常在结直肠癌肝转移分期中更有用。多排螺旋计算机断层扫描（MDCT）仍然是术前规划、病变检测和肿瘤监测的主要成像方式。磁共振成像（MRI）和对比增强超声检查（US）在解决不确定病变的特征描述问题方面具有重要价值，而对比增强术中超声检查（CE-IOUS）可能是肝切除术前新的金标准分期工具。最终，成像策略必须根据临床情况进行调整，以获取最相关的信息，从而优化利用现有的成像资源。
