Motivation: The differentiation between benign and malignant liver lesions is critical for clinical decision-making, yet traditional methods may not always provide clear distinctions. Goal(s): To evaluate the efficacy of Magnetic Resonance Elastography (MRE) in differentiating benign and malignant liver lesions and to assess its potential in predicting the prognosis of malignant tumors. Approach: Retrospective analysis of 207 liver lesion cases using 2D MRE scans to measure elasticity. Results: Malignant lesions had higher elasticity (AUC 0.843), with a 3.90 kPa cutoff. Post-treatment changes were significant in disease progression. Impact: MRE demonstrates potential as a non-invasive imaging biomarker for distinguishing benign from malignant liver lesions and assessing treatment response in malignant tumors. This could facilitate more informed clinical decisions and improve patient outcomes.
