Learning objectives
Accurate detection and characterization of focal liver lesions (FLLs) are important for treatment planning for patients with liver neoplasms such as hepatocellular carcinoma (HCC) and metastases.
The size and number of lesions can affect therapy.
For example,
patients with limited resectable metastatic lesions may benefit from curative resection (1) and patients with fewer than three small HCCs are candidates for liver transplantation (2).
Patients with more extensive disease should instead undergo transarterial chemoembolization,
radiofrequency ablation,
or systemic chemotherapy (3,4).
For FLL detection and characterization,
magnetic...
Background
Hepatic lesions arise based on liver anatomy.
In this exhibit we will describe the use of conventional and contrast enhanced ultrasonography (US),
computed tomography (CT),
conventional and contrast enhanced magnetic resonance (MR) imaging,
focusing on the role of hepatospecific contrast agents in MR in the diagnosis of Hepatocellular Carcinoma (HCC) in the cirrhotic liver.
Furthermore,
we will analyze the role of Diffusion Weighted Imaging (DWI) in the evaluation of recurrence of HCC after thermoablation procedure.

Imaging findings OR Procedure details
We will present the features of commonly encountered benign and malignant liver lesions on CT and MR imaging.
Conclusion
CEUS enables to make more accurate characterization of focal liver lesions in case of suspected liver tumors.
DWI MR imaging was better than standard breath-hold T2-WI for FLL detection and was equal to breath-hold T2-WI for FLL characterization.
90% of cases had a complete response to both CEUS and MR with DWI sequences.
