To conduct a systematic literature review of imaging techniques and findings in patients with peribiliary liver metastasis.
Several electronic datasets were searched from January 1990 to June 2017 to identify studies assessing the use of different imaging techniques for the detection and staging of peribiliary metastases.
The search identified 44 studies, of which six met the inclusion criteria and were included in the systematic review. Multidetector computed tomography (MDCT) is the technique of choice in the preoperative setting and during the follow-up of patients with liver tumors. However, the diagnostic performance of MDCT for the assessment of biliary tree neoplasms was low compared with magnetic resonance imaging (MRI). Ultrasound (US), without and with contrast enhancement (CEUS), is commonly employed as a first-line tool for evaluating focal liver lesions; however, the sensitivity and specificity of US and CEUS for both the detection and characterization are related to operator expertise and patient suitability. MRI has thus become the gold standard technique because of its ability to provide morphologic and functional data. MRI showed the best diagnostic performance for the detection of peribiliary metastases.
MRI should be considered the gold standard technique for the radiological assessment of secondary biliary tree lesions.
对肝门周围肝转移患者的成像技术及检查结果进行系统的文献综述。
检索了1990年1月至2017年6月期间的多个电子数据集，以确定评估不同成像技术用于检测肝门周围转移灶及进行分期的研究。
检索到44项研究，其中6项符合纳入标准并被纳入系统评价。多排螺旋计算机断层扫描（MDCT）是肝肿瘤患者术前及随访期间的首选技术。然而，与磁共振成像（MRI）相比，MDCT对胆管肿瘤的诊断效能较低。超声（US），无论有无对比增强（CEUS），通常作为评估肝脏局灶性病变的一线工具；然而，US和CEUS在检测及特征描述方面的敏感性和特异性与操作者的专业水平及患者的适用性有关。因此，MRI因其能够提供形态学和功能数据而成为金标准技术。MRI在检测肝门周围转移灶方面显示出最佳的诊断效能。
MRI应被视为对继发性胆管病变进行放射学评估的金标准技术。
