Enhancing liver diffusion-weighted imaging quality with correlation-weighted averaging: notable benefits in the left hepatic lobe
Diffusion-weighted imaging (DWI) is an essential sequence in liver MRI for detecting abdominal lesions and differentiating benign from malignant ones using apparent diffusion coefficient (ADC) values [1–4]. Echo-planar imaging (EPI) is the most commonly used sequence for DWI because its rapid readout makes it relatively robust against motion. However, it has inherent limitations, including a low signal-to-noise ratio (SNR) and susceptibility to signal loss caused by phase dispersion [5].

Enhancement slope of ultrafast dynamic contrast-enhanced MRI: a promising biomarker for assessing Crohn’s disease activity
To investigate the diagnostic value of the enhancement slope in an 18-second ultrafast dynamic contrast-enhanced MRI (DCE-MRI) using differential subsampling with Cartesian ordering (DISCO) in quantifying Crohn’s Disease (CD) activity.

Inter-rater reliability of a classification systems for distal radius fractures using radiology text and x-rays: what really matters?
Distal radius fractures (DRF) are one of the most common fractures among adults presenting to hospital [1,2] and generally result from a fall on an outstretched hand. [3] The diagnosis of a DRF is made clinically and radiographically with orthogonal radiographs (x-rays) of the wrist. Treatment can be nonoperative or operative depending on fracture stability and fracture displacement as well as patient age and activity demands. The incidence of these types of fractures is high in adolescent males…

Characterising liver lesions from free-text computer tomography reports – A real-world multicentre analysis
The Liver Imaging Reporting and Data System standardises acquisition, interpretation, reporting, and data collection for imaging examination in patients at risk of developing hepatocellular carcinoma. Although many studies have validated its use, showing its excellent diagnostic performance and reliability, its adoption is not universal[1,2]. Many radiologists still prefer free-text reporting and have cited unfamiliarity, lack of routine use by referring clinicians, perceived complexity, and per…

Synovitis mediates the association between medial meniscal extrusion and subchondral bone denudation in knee osteoarthritis: Data from the FNIH OA biomarkers consortium
Knee osteoarthritis (KOA) remains one of the most prevalent musculoskeletal disorders worldwide, representing a primary cause of chronic pain and long-term disability among middle-aged and older adult populations [1]. Current epidemiological projections indicate a concerning rise in the global burden of KOA, with an estimated increase of 74.9 % (range: 59.4 %–89.9 %) by 2050, compared to 2020 figures [2]. Beyond its clinical impact, KOA constitutes a substantial driver of healthcare expenditures…

Development and validation of a radiomics model for lactate metabolism genes-based stratification and prognostic prediction in head and neck squamous cell carcinoma
Head and Neck Squamous Cell Carcinoma (HNSCC) represents a notably diverse group of malignant neoplasms that arise from the mucosal epithelium found in the oral cavity, pharynx, and larynx. This type of carcinoma accounts for nearly 90 % of all tumors located in the head and neck region [1]. Globally, there are over 830,000 new cases of HNSCC each year and 430,000 deaths; the 5-year survival rate has long hovered around 40 %-60 % [2]. Current standard treatment regimens primarily involve surgica…

Spectral CT-Based habitat imaging for the prediction of occult lymph node metastasis in resectable pancreatic ductal Adenocarcinoma: Pathological validation via collagen ratio
Pancreatic ductal adenocarcinoma (PDAC) is recognized as one of the most aggressive malignancies, with a dismal 5-year survival rate nearing 13% [1]. Early lymph node metastasis (LNM), along with aggressive tumor growth, represents a defining biological characteristic of PDAC and serves as a strong independent predictor of poor clinical outcomes [2]. Notably, N0 patients exhibit a significantly higher 5-year survival rate compared to N1/2 patients (57.1% vs. 25.0%) [3]. Neoadjuvant therapy is re…

Performance analysis of liver segmentation using nn-UNet TotalSegmentator: Focus on atypical livers, pathologies, and variants
Several diseases and treatments affect the liver and its volume, such as cirrhosis, hepatitis, liver metastases, hepatocellular carcinoma, and chemotherapy. Most abdominal CT examinations cover the entire liver volume, which could be used as a diagnostic imaging biomarker. However, traditional manual estimation is time-consuming and subject to errors and interobserver variability, which fosters the development of automatic segmentation solutions [1,2].

Ultrashort echo time MRI radiomics as a predictor of clinical outcomes in patellar tendinopathy: Insights from a large prospective clinical trial
To evaluate the predictive utility of radiomic features extracted from ultrashort echo time (UTE) MRI in comparison to conventional proton density (PD) sequences for short-term (24-week) and long-term (5-year) clinical outcomes in patients with patellar tendinopathy (PT) receiving exercise therapy.
