Abstract
• Magnetic resonance imaging is a useful tool for characterizing both benign and malignant pediatricliver lesions.
• characteristic patterns of signal intensity and postcontrast enhancement can narrow the differential diagnosis and help determine whether a liver lesion is likely benign or malignant.
• Use of hepatocyte-specific contrast agents, such as gadoxetate disodium, can provide additionalin formation to help refine the differential diagnosis for focal liver lesions.
MR imaging offers several advantages to CT and US when imaging benign and malignant pediatric hepatic tumors. Soft tissue characterization and the lack of ionizing radiation are two of its strongest characteristics. Although an exact diagnosis may not be achievable with every patient, MR imaging is a powerful tool that can offer a focused differential and help facilitate the choice of which lesions to biopsy or resect. The recent addition of HSAs further strengthens radiologists’ capability to provide referring clinicians with focused and specific information.
