Improving prognostication in patients with hepatocellular carcinoma undergoing loco-regional therapy using pre- and post-locoregional therapy scores
ConclusionIn patients with HCC undergoing LRT, the mod-BCLC stages have subgroups with variable overall TFS. The NIACE score, HAP score, and ABCR score identified differential prognoses is within mod-BCLC stages and characterized subgroups with different TFS following LRT (TAE). Integration of these scoring systems into treatment decisions would help to improve prognostication within respective mod-BCLC groups, which may help with more customized treatment allocation.Graphical abstract (Source: Abdominal Imaging)

Intravoxel incoherent motion diffusion-weighted imaging for evaluating the pancreatic perfusion in cirrhotic patients
ConclusionThe IVIM-derived perfusion-related parameter (f value) could be helpful for the evaluation of pancreatic perfusion in liver cirrhosis. Our data also suggest that the blood perfusion decrease in the pancreas is present in liver cirrhosis, and the pancreatic perfusion tends to decrease with the increasing severity of hepatic function.Trial registrationTrial registration number is 2021-ky-68 and date of registration for prospectively registered trials is February 23, 2022.Graphical abstract (Source: Abdominal Imaging)

Traveling gallstones: review of MR imaging and surgical pathology features of gallstone disease and its complications in the gallbladder and beyond
AbstractGallstone-related disease comprises a spectrum of conditions resulting from biliary stone formation, leading to obstruction and inflammatory complications. These can significantly impact patient quality of life and carry high morbidity if not accurately detected. Appropriate imaging is essential for evaluating the extent of gallstone disease and assuring appropriate clinical management. Magnetic Resonance Imaging (MRI) techniques (including Magnetic Resonance Cholangiopancreatography (MRCP) are increasingly used for diagnosis of gallstone disease and its complications and provide high contrast resolution and facili...

Prediction of macrotrabecular-massive hepatocellular carcinoma by using MR-based models and their prognostic implications
ConclusionMR-based clinical and radiomic models have the potential to accurately diagnose MTM-HCC. Moreover, the radiomics signature designed to identify MTM-HCC also can be used to predict prognosis in patients with HCC, realizing the diagnostic and prognostic aims at the same time.

Performance of current versus modified CEUS LI-RADS in the diagnosis of non-hepatocellular carcinoma malignancies
ConclusionCEUS LR-M has high sensitivity in diagnosing non-HCCMs. For LR-M nodules with nonrim arterial phase hyperenhancement and early washout, advancing the time of early washout to< 45 s has a minimal impact on the sensitivity of LR-M in diagnosing non-HCCMs compared to the condition of increasing the marked washout within 5 min.

PET/MRI for evaluation of patients with pancreatic cancer
AbstractPancreatic cancers are the third leading cause of cancer-related death in the USA and outcomes remain poor despite improvements in imaging and treatment paradigms. Currently, computed tomography (CT) and magnetic resonance imaging (MRI) are frequently utilized for staging and restaging of these malignancies, but positron emission tomography (PET)/CT can play a role in troubleshooting and improve whole-body staging. PET/MRI is a novel imaging modality that allows for simultaneous acquisition of PET and MRI images, leading to improved image quality and potential increased sensitivity. Early studies suggest that PET/M...
