Body Composition in the General Population: Whole-body MRI-derived Reference Curves from Over 66 000 Individuals
May 5, 2026
The authors aimed to calculate age-, sex-, and height-normalized body composition (BC) metrics from MRI scans of over 66,000 individuals to assess their prognostic value for cardiometabolic outcomes beyond traditional risk factors. They found that specific BC z-scores were significantly associated with increased risks of diabetes, major adverse cardiovascular events, and all-cause mortality. An open-source z-score calculator was developed to facilitate the use of these metrics in clinical settings.
Comparative Precision of 3D MRE and 2D MRE for Measurement of Liver Stiffness in Adults with Severe Obesity
May 5, 2026
The authors aimed to compare the precision of two-dimensional (2D) and three-dimensional (3D) MR elastography (MRE) in measuring liver stiffness in adults with severe obesity. Their findings indicate that 3D MRE demonstrates superior test-retest repeatability, between-field-strength reproducibility, and between-day reproducibility compared to 2D MRE, although it also has a higher technical failure rate.
Associations of MRI-derived Paraspinal IMAT and LMM with Cardiometabolic Risk Factors: Results from a German Cohort
May 5, 2026
The authors aimed to investigate the independent and combined associations of intermuscular adipose tissue (IMAT) and lean muscle mass (LMM) with cardiometabolic risk factors in individuals without pre-existing conditions. Their findings revealed that increased IMAT was linked to higher odds of hypertension and dyslipidemia, while greater LMM was associated with lower odds of these risk factors, particularly in men. Overall, the study highlights the significance of IMAT and LMM in assessing cardiometabolic health in a healthy population.
Diffusion-weighted Imaging of the Liver: Primed for New Business
May 5, 2026
The authors explore the current state and future potential of diffusion-weighted imaging (DWI) in the liver, particularly its role in detecting and characterizing lesions, assessing diffuse parenchymal disease, and monitoring cancer treatment responses. They highlight the advantages of DWI as a cost-effective imaging strategy while acknowledging the technical challenges that remain. The review aims to elucidate how DWI can enhance liver imaging practices and its implications for clinical applications.
Consortium on Bridging Radiation Segmentectomy (COBRAS): A Multicenter Study of Complete Pathologic Necrosis in Hepatocellular Carcinoma
May 5, 2026
The study aimed to evaluate the outcomes of glass microsphere radiation segmentectomy in achieving complete pathologic necrosis (CPN) in patients with treatment-naive hepatocellular carcinoma (HCC) prior to liver transplant. The findings revealed a CPN rate of 68%, with specific treatment parameters—such as microsphere activity, dose, and angiosome-to-tumor volume ratio—identified as independent predictors of achieving CPN. This research highlights the importance of optimizing these parameters to improve patient outcomes in liver transplantation for HCC.
MRI Diagnosis of Meniscus Tears in the Knee: An Updated Systematic Review and Meta-analysis
Apr 28, 2026
The authors aimed to update the diagnostic performance benchmarks of MRI for detecting meniscus tears in the knee compared to arthroscopy, analyzing factors that influence accuracy. Their systematic review and meta-analysis of 75 studies revealed that MRI sensitivity was higher for medial meniscus tears, while specificity was greater for lateral tears, with certain imaging criteria enhancing diagnostic performance. Overall, the study confirmed consistently high accuracy for knee MRI in diagnosing meniscus tears across various study designs.
Quantitative Phase-resolved Functional Lung MRI Prediction of Disease Progression in Connective Tissue Disease-associated Interstitial Lung Disease
Apr 28, 2026
The authors aimed to investigate whether ventilation and perfusion parameters quantified through phase-resolved functional lung (PREFUL) MRI can predict disease progression in patients with connective tissue disease-associated interstitial lung disease (CTD-ILD). Their findings indicate that distinct pulmonary perfusion phenotypes identified by PREFUL MRI correlate with disease progression over one year, demonstrating the potential of these functional parameters in guiding clinical management of CTD-ILD.
CT-based Opportunistic Screening for Adding Clinical Value: How I Do It
Apr 28, 2026
The authors explore how to effectively implement opportunistic CT screening to enhance clinical value by leveraging cardiometabolic information from routine scans. They discuss the potential of explainable AI algorithms to automate the detection of conditions like osteoporosis and cardiovascular disease, which could lead to preventive interventions. The paper emphasizes the importance of addressing logistical and ethical considerations to maximize the benefits of this approach in personalized medicine.
Association between CT-evaluated Poststenotic Dilatation in Human Renal Artery Stenosis and Kidney Release of MCP-1
Apr 28, 2026
The authors investigate the mechanisms underlying poststenotic dilatation (PSD) in patients with renal artery stenosis (RAS) and its association with kidney damage, specifically focusing on the release of monocyte chemoattractant protein-1 (MCP-1). Their findings reveal that higher levels of MCP-1 in the stenotic kidney correlate positively with the dilatation-diameter ratio and are associated with lower kidney function, suggesting a potential link between PSD and renal injury. Additionally, while percutaneous transluminal renal angioplasty did not improve kidney function, it did lead to regression of PSD, which was inversely related to MCP-1 levels.
Case 349
Apr 28, 2026
This case report details a 76-year-old man presenting with worsening binocular diplopia, dysarthria, and dizziness, alongside neurological findings suggestive of a central nervous system disorder. The authors aim to explore the underlying etiology of these symptoms, as extensive diagnostic testing has ruled out common causes, while cerebrospinal fluid analysis indicates the presence of oligoclonal bands, suggesting a possible demyelinating condition.
