Presentation of typical enhancement patterns of various histologic types of focal liver lesions (FLLs) on Contrast Enhanced Ultrasound (CEUS). Explanation of their haemodynamic behaviour post contrast injection based on their histology and recognition of atypical patterns of contrast enhancement.

Review of the status of CEUS as the first imaging method to be performed when a FLL is found on baseline US. Description of various types of lesions and their different patterns of US contrast agents’ enhancement, depending on their blood flow from the hepatic artery and portal vein during the arterial, portal and late phase. Explanation of diagnosis based on these typical patterns and acknowledgement of enhancement in atypical ways. Presentation of cases of FLLs with typical and atypical behaviour on CEUS and explanation of the pathophysiological basis for these features based on their histology. Analysis of different behaviour of US, CT and MR contrast agents resulting in potential different behaviour of the same lesion in these modalities.
