Objective: A new computer tool is proposed to distinguish between focal nodular hyperplasia (FNH) and an inflammatory hepatocellular adenoma (I-HCA) using contrast-enhanced ultrasound (CEUS). The new method was compared with the usual qualitative analysis.

Methods: The proposed tool embeds an "optical flow" algorithm, designed to mimic the human visual perception of object transport in image series, to quantitatively analyse apparent microbubble transport parameters visible on CEUS.

Objective: MRI is crucial for the classification of hepatocellular adenomas (HCA) into subtypes. Our objective was to review and increase MRI criteria for subtype classification and define the limits.

Methods: Pathological and radiological data of 116 HCAs were retrospectively analyzed to investigate MRI features of HCA pathological subtypes.

Background And Aims: Focal nodular hyperplasia with major sinusoidal dilatation (FNH-sd) is a misleading entity, with some features resembling inflammatory hepatocellular adenoma (HCA). We aimed to assess the performance of contrast-enhanced ultrasound (CEUS) for the diagnosis of FNH-sd.

Methods: Four histologically proven FNH-sd nodules in four patients were investigated with both MRI and CEUS imaging.

Article Synopsis
  • The article reviews discussions from the Fifth International Forum for Liver MRI, emphasizing the use of gadoxetic acid-enhanced MRI in liver diagnostics.
  • Gadoxetic acid-enhanced MRI demonstrates high sensitivity and specificity in diagnosing liver tumors, particularly benefiting the characterization of borderline lesions during hepatobiliary phase imaging.
  • There is a call for standardized criteria to improve the interpretation of this imaging technique, especially for patients with cirrhosis or elevated risk for hepatocellular carcinoma.
