Since its introduction in clinical practice, ultrasound technology has greatly impacted patient management, particularly in the case of liver diseases, where hepatologists usually perform ultrasound examinations. Clinicians are increasingly aware of the great potential of ultrasound waves and of the recent innovations that exploit the mechanical properties of ultrasound waves. Thus, at present, not only B-mode ultrasound but also contrast-enhanced ultrasound and, more recently, elastosonography are used worldwide in various settings. This review aims to describe why clinicians should be aware of ultrasound-based techniques, how they should use these techniques for assessing focal liver lesions, and how these techniques impact patient management. We will review the clinical potential of ultrasound-related techniques, starting from lesion detection, moving to characterization, and concluding with their utility in guiding treatments and analyzing their effects.
