The increasingly common use of ultrasound examination of the liver has led to increased detection of hepatic tumours, showing a hitherto unsuspected prevalence. Improved techniques in MRI, such as dynamic sequences and new contrast media, are ameliorating the detection and characterization of the lesions, in particular with regard to computed tomography. In addition, since MRI is more sensitive to different components than in computed tomography, it permits better study of diffuse diseases such as haemochromatosis or fatty infiltration, particularly in pseudotumoural forms. The continuing progress in system improvement makes MRI an excellent method for diagnosis of bile duct disorders, especially in case of obstruction.
肝脏超声检查的日益普遍使用导致肝肿瘤的检出率增加，显示出此前未被怀疑的患病率。MRI技术的改进，如动态序列和新型造影剂，正在改善病变的检测和特征描述，特别是与计算机断层扫描相比。此外，由于MRI对不同成分的敏感性高于计算机断层扫描，它能够更好地研究诸如血色素沉着症或脂肪浸润等弥漫性疾病，尤其是在假瘤形式中。系统改进的持续进展使MRI成为诊断胆管疾病的优秀方法，特别是在梗阻情况下。
