摘要
肝脏是许多恶性肿瘤最易转移的靶器官之一,与肝内原发肿瘤相比,转移性肿瘤所占比例较高。是否存在肝转移灶是恶性肿瘤治疗方案制定的重要影响因素,因此,肝转移灶的检出与定性尤为重要。肝转移灶的主要影像学检查方法包括超声(US)、电子计算机断层扫描(CT)、磁共振成像(MRI)、正电子发射计算机断层显像(PET/CT)及PET/MRI。本文重点分析以上成像方法在肝转移瘤诊断方面的优势及局限性,并着重叙述各种成像方法的应用进展。
The liver is one of the most easily metastasized target organs of many malignant tumors and the proportion of metastatic tumors is higher than that of intrahepatic primary tumors.The existence of liver metastases is an important factor in the treatment of malignant tumors.Therefore,the detection and characterization of liver metastases are particularly important.The main imaging methods for hepatic metastases include ultrasound(US),computed tomography(CT),magnetic resonance imaging(MRI),positron emission computed tomography(PET/CT)and PET/MRI.In this paper,the advantages and limitations of the above imaging methods in the diagnosis of liver metastasis are analyzed,and the application progress of various imaging methods is emphasized.
