MRI has become the most important imaging modality for detecting and characterizing focal liver lesions. The introduction of high-field-strengths, such as 3 Tesla MR imaging, in combination with the parallel imaging technique, has led to significant improvements in spatial and temporal resolution and has established this technique as a valuable asset in daily clinical practice. New techniques, such as diffusion-weighted imaging, may improve MR imaging sensitivity and specificity in the diagnostic workup of focal liver lesions. The tailored administration of various nonspecific and liver-specific contrast agents enables clinicians to increase the detection rate and improve the characterization of the different focal liver lesions. This article describes the usefulness of these imaging techniques in detecting and characterizing the most common benign focal liver lesions.
磁共振成像（MRI）已成为检测和鉴别肝脏局灶性病变最重要的成像方式。高场强（如3特斯拉磁共振成像）与并行成像技术相结合，显著提高了空间和时间分辨率，并使该技术成为日常临床实践中的一项宝贵工具。诸如扩散加权成像等新技术，可能会提高MRI在肝脏局灶性病变诊断检查中的敏感性和特异性。各种非特异性和肝脏特异性对比剂的定制给药，使临床医生能够提高不同肝脏局灶性病变的检出率并改善其特征描述。本文介绍了这些成像技术在检测和鉴别最常见的肝脏良性局灶性病变方面的作用。
