The investigation of hepatobiliary tumors, in the pediatric population, usually begins with an ultrasonographic (US) examination. It is readily available without ionizing radiation and does not need sedation. Therefore US is an outstanding imaging modality for screening and follow-up. Doppler and color Doppler interrogation are part of the examination to assess vascularity of the lesions and vascular anatomy. Magnetic resonance imaging is a comprehensive imaging modality with multiplanar capability to assess the liver parenchyma, gallbladder, and biliary tree and is free of ionizing radiation. This article highlights the current status of imaging of the most common hepatobiliary tumors in children.
对于儿科人群肝胆肿瘤的研究，通常始于超声（US）检查。超声检查易于进行，无需电离辐射，也不需要镇静。因此，超声是筛查和随访的优秀成像方式。多普勒和彩色多普勒检查是评估病变血管情况和血管解剖结构的检查的一部分。磁共振成像（MRI）是一种全面的成像方式，具有多平面成像能力，可用于评估肝实质、胆囊和胆管系统，且无电离辐射。本文重点介绍了儿童最常见肝胆肿瘤的成像现状。
