Core Tip

Core Tip: Liver magnetic resonance imaging (MRI) is a fundamental radiological technique in patients with focal liver lesions as it allows, with its multiparametric approach, optimal non-invasive tissue characterization. Liver MRI can be highly effective in distinguishing pseudotumor from tumors, as well as benign from malignant lesions and can also be used for differential diagnosis. Although histopathological assessment sometimes has an important role in definitive diagnosis, MRI is a key imaging modality in the diagnosis of liver lesions with a great impact on patient management.
