Radiological imaging methods used at a large scale in the assessment of hepatic lesions include: Ultrasound, computed tomography and magnetic resonance. To further characterize these lesions, specific contrast agents may be added, thus revealing the vascularity of the lesions.
This review focuses on gadoxetic acid, which is a hepatospecific contrast agent used in MRI. The aim of the review is to briefly explain the mechanism of GA enhancement, describe the enhancement patterns of some benign and malignant hepatic lesions and discuss possible advantages of GA over standard contrast agents.
The role of GA in functional MR cholangiography and the idea of accessing liver function by measuring parenchymal enhancement will also be explained.
在评估肝脏病变时，广泛使用的放射影像学方法包括：超声、计算机断层扫描和磁共振。为了进一步描述这些病变，可能会添加特定的对比剂，从而显示病变的血管生成。
本综述重点介绍钆塞酸，这是一种用于 MRI 的肝特异性对比剂。综述的目的是简要解释 GA 增强的机制，描述一些良性和恶性肝脏病变的增强模式，并讨论 GA 相对于标准对比剂的可能优势。
还将解释 GA 在功能磁共振胆胰管成像中的作用以及通过测量实质增强来评估肝功能的想法。
