**3. Conclusions**

Elastography is a noninvasive, US-based, real-time imaging modality that can be a valuable tool in orienting the diagnosis and can be integrated into imaging protocols already involving the standard US to obtain a multiparametric approach. Although SWE has excellent potential in characterizing FLLs, further research is needed to evaluate the accuracy of these methods and set specific cut-off values.

Published studies have conflicting results, and no consensus has been so far established. This is the main reason that the WFUMB [13] and EFSUMB [21] guidelines do not recommend the use of elastography for differentiation between malignant and benign FLLs. Further multicentric studies with larger and homogenous cohorts are required for these techniques to be appropriately used routinely in a clinical setting.
