Multiparametric magnetic resonance imaging, diffusion-weighted magnetic resonance imaging, and magnetic resonance elastography: differentiating benign and malignant liver lesions

Le résumé fourni par la source

PURPOSE: This study investigates the accuracy of multiparametric magnetic resonance imaging (mpMRI), diffusion-weighted imaging (DWI), and magnetic resonance elastography (MRE) in differentiating benign and malignant liver lesions. METHODS: This retrospective study included patients with focal liver lesions who underwent MRI and MRE between 2018 and 2022. Based on histopathologic analyses or follow-up imaging findings, 70 solid liver lesions were retrospectively evaluated as benign (n = 20) or malignant (n = 50). RESULTS: /s (AUC: 0.861, sensitivity 89.5%, specificity 81.2%), and a stiffness of 3.77 kPa (AUC: 0.848, sensitivity 85%, specificity 75%). CONCLUSION: Combined mpMRI, DWI, and MRE provide high diagnostic accuracy, with ADC and MRE offering superior performance in differentiating malignant from benign liver lesions. CLINICAL SIGNIFICANCE: This article highlights the accuracy of mpMRI, MRE, and DWI in distinguishing between malignant and benign liver lesions. These findings support the integration of mpMRI, DWI, and MRE into clinical practice for non-invasive liver lesion characterization.
