Summary: This study investigated the predictive value of gadoxetic acid-enhanced MRI features on the pathological grade, microvascular invasion, and expression of cytokeratin-19 in hepatocellular carcinomas. The results showed that peritumoral enhancement, peritumoral hypointensity, and other imaging features were independent predictors of the pathological grade, microvascular invasion, and cytokeratin-19 expression. Additionally, peritumoral hypointensity and poor pathological grades were found to be independent predictors of recurrence.

Summary: This study showed that Gadoxetic acid-enhanced MRI combined with CECT had higher diagnostic performance than CECT alone for detecting liver metastases in patients with PDAC. The incremental values were comparable between the abbreviated MRI and standard MRI.

Summary: Gadoxetic acid-enhanced MRI plays a crucial role in the precise staging and treatment decision-making of primary liver cancer and metastatic liver disease. Multidisciplinary care, evidence-based imaging protocols, and standard nomenclature in international guidelines were also highlighted for improving patient management and communication between medical centers.

Summary: This is a case report of a giant pedunculated hepatic hemangioma, which is rare and associated with additional risks such as torsion. An MRI examination revealed a mass measuring approximately 6.4 x 7 cm in the left upper abdomen, which was confirmed to be a hemangioma. Compared to previously reported cases, we systematically summarized the characteristics of this case.

Summary: This study aimed to characterize MTM-HCC on gadoxetic acid-enhanced MRI and evaluate the diagnostic accuracy and prognostic value of these imaging characteristics. Two diagnostic criteria were developed for MTM-HCC based on MRI findings which showed good sensitivity and specificity, and were associated with poor outcomes after hepatic resection.

Summary: Gd-EOB-DTPA-enhanced MRI is widely used in clinical practice. Optimizing hepatobiliary phase (HBP) acquisition according to individual hepatic function is a good strategy, and a more concise and efficient HBP acquisition method is still expected to be developed in the future.

Summary: Multivariable analysis identified irregular margins, centripetal or internal nodular enhancement in the transitional phase, and absence of diffusion restriction as significant MRI features for diagnosing hepatic sclerosing hemangioma. When at least two significant imaging features were present, the sensitivity, specificity, and accuracy for diagnosing sclerosing hemangioma were high.

Summary: The study evaluated the clinical usefulness of a simplified LI-RADS for diagnosing hepatocellular carcinomas (HCCs) of 30 mm or smaller at gadoxetic acid-enhanced MRI. The results showed that the simplified LI-RADS demonstrated higher sensitivity and reduced time for category assignment compared to LI-RADS 2018.

Summary: Gd-EOB-MRI has a higher sensitivity for detecting colorectal liver metastases (CRLM) compared to contrast-enhanced computed tomography (CECT). However, the details of false-positive lesions for each imaging modality are unknown. This study evaluated cases undergoing hepatectomy for CRLM and found that Gd-EOB-MRI had a 7% false-positive rate. False-positive lesions were smaller in size and more frequently located near the liver surface or vasculobiliary structures.

Summary: This study investigated the role of gadoxetic acid-enhanced MRI based on LI-RADS v2018 imaging features in the prognosis prediction of sHCC patients treated with RFA. A total of 204 patients were enrolled, and a predictive nomogram was formulated. The nomogram showed superior predictive performance in both the training and validation groups.

Summary: The functional liver imaging score (FLIS) was validated for predicting hepatic function in gadoxetic acid-enhanced MRI, showing strong correlation with Child-Pugh score and aiding in predicting the development of first hepatic decompensation.

Summary: This study aimed to determine the incidence of transient severe motion artifact (TSM) on arterial phase gadoxetic acid-enhanced magnetic resonance imaging of the liver and investigate the causes of heterogeneity in the published literature. The pooled incidence of TSM varied across studies and was associated with the geographical region of studies and the definition of TSM. Careful interpretation of results reporting TSM might therefore be needed.

Summary: This study described the imaging features of intraosseous hemangiomas located outside of the mobile spine and calvarium. The results showed that these hemangiomas exhibited more aggressive imaging characteristics compared to vertebral hemangiomas, including cortical permeation, soft tissue mass, amorphous increased density mimicking osteoid matrix, and increased FDG activity.
