Radiomics in CT and MR imaging of the liver and pancreas: tools with potential for clinical application
AbstractRadiomics allows the extraction of quantitative imaging features from clinical magnetic resonance imaging (MRI) and computerized tomography (CT) studies. The advantages of radiomics have primarily been exploited in oncological applications, including better characterization and staging of oncological lesions and prediction of patient outcomes and treatment response. The potential introduction of radiomics in the clinical setting requires the establishment of a standardized radiomics pipeline and a quality assurance program. Radiomics and texture analysis of the liver have improved the differentiation of hypervascul...

A correlation study between prostate necrosis rate calculated by 3D Slicer software and clinical efficacy of prostatic artery embolization, along with an analysis of predictors of clinical success after prostatic artery embolization
ConclusionThe higher the prostate necrosis rate at 1-month after PAE, the better the clinical efficacy at 1-year after PAE is likely to be, and the prostate necrosis rate at 1-month after PAE is expected to become a predictor of clinical success after PAE. (Source: Abdominal Imaging)

Shear wave elastography of kidneys in children: utility in distinguishing steroid-resistant and steroid-sensitive nephrotic syndrome
ConclusionThe mean SWE was higher in children with SRNS. While SWE has potential to differentiate SSNS from SRNS, a different study design where SWE is performed at presentation is needed for confirmation. (Source: Abdominal Imaging)

Prediction of locally advanced rectal cancer response to neoadjuvant chemoradiation therapy using volumetric multiparametric MRI-based radiomics
ConclusionRadiomic models obtained from pre-treatment MRI show good to excellent performance for the prediction of pCR in patients with LARC, superior to clinical parameters and CEA. A larger study is needed for confirmation of these results.Graphical abstract (Source: Abdominal Imaging)

Ultrasound findings of hepatic epithelioid hemangioendothelioma: comparison with other malignant hepatic tumors
ConclusionHEHE mainly performed multiple hypoechoic lesions on CUS and displayed greater odds of synchronous enhancement in arterial phase, iso- or hypo-enhancement in peak time and wash out more quickly on CEUS, which allowed for differentiation from other common malignant tumors.Graphical abstract (Source: Abdominal Imaging)

CT findings in idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) and comparison to other colitides
ConclusionIMHMV is a rare chronic non-thrombotic ischemia predominantly involving the rectosigmoid colon. CT features that may aid in differentiating IMHMV from other causes of left-sided colitis include marked bowel wall thickening with decreased enhancement, IMV and peripheral mesenteric venous occlusion or tapering, and early filling of dilated veins on CTA.Graphical abstract (Source: Abdominal Imaging)

Preoperative evaluation of MRI features and inflammatory biomarkers in predicting microvascular invasion of combined hepatocellular cholangiocarcinoma
ConclusionInflammatory biomarkers and MRI features could be potential predictors for MVI in cHCC-CCA. The combined model, derived from inflammatory biomarkers and MRI features, showed good performance in preoperatively predicting MVI in cHCC-CCA patients.Graphical abstract (Source: Abdominal Imaging)
