Ingestion or aspiration of foreign bodies (FBs) is a common reason for pediatric emergency department visits. In this document, three variants were developed. In Variant 1 (suspect ingested or aspirated FB, initial imaging), neck, chest, abdomen, and pelvis radiographs are usually appropriate to identify the presence and location of a swallowed or inhaled FB. Low-dose noncontrast chest CT may also be appropriate when there is high suspicion for radiolucent FB. In Variant 2 (suspect ingested FB, …

A New Chapter for the ACR Appropriateness Criteria®
The ACR Appropriateness Criteria® (AC) have long been a trusted source for evidence-based imaging recommendations, guiding clinicians and referring providers in making the most appropriate imaging or treatment decisions across a wide range of clinical scenarios. As the landscape of medicine continues to evolve rapidly, so too must the way we deliver timely, relevant, and accessible guidance to the medical community.

Idiopathic pulmonary fibrosis and progressive pulmonary fibrosis: correlation between radiological progression criteria and pulmonary function tests
With the increasing use of antifibrotic therapies for idiopathic pulmonary fibrosis (IPF) and progressive pulmonary fibrosis (PPF) in non-IPF interstitial lung diseases (ILDs), radiological evaluation has become essential for diagnosis, treatment planning, and monitoring disease progression [1]. Although pulmonary function tests (PFTs) guide treatment decisions and assess disease progression, their reliability is limited by variability related to patient or technician factors [2,3]. Therefore, r…

Acceleration of chemical shift encoding-based water-fat imaging for pancreatic proton density fat fraction mapping in a single breath-hold: Data from the LION study
Non-alcoholic fatty pancreas disease (NAFPD) is generally defined as increased fat deposition in the pancreas [1], and is commonly associated with obesity and metabolic syndrome [2,3], as well as with metabolic dysfunction-associated steatotic liver disease (MASLD) [4–6]. While there is agreement on the impact of pancreatic steatosis on exocrine function [6–8], the effect of pancreatic steatosis on endocrine function is a widely discussed topic [8–11]. It is important to note that pancreatic fat…

Research progress and clinical utility of multi-parameter orbital MRI in thyroid-associated ophthalmopathy
Thyroid-associated ophthalmopathy (TAO), also known as Graves’ ophthalmopathy, is a disfiguring and potentially sight-threatening autoimmune disease [1,2]. While it most commonly affects patients with Graves’ disease (approximately 90 % of cases), it can also manifest in patients who are euthyroid or hypothyroid. Its complex pathophysiology is driven by an autoimmune response targeting the thyrotropin (TSHR) and insulin-like growth factor-1 (IGF-1R) receptor complex on orbital fibroblasts. This …

Preoperative MRI for non-invasive assessment of pancreatic acinar cell composition
This study explores the predictive power of preoperative MRI in evaluating pancreatic acinar cell composition. We aimed to determine whether MRI-derived signal intensity ratios could serve as reliable biomarkers for preoperative assessment.

Distribution of coronary artery calcium volume and density by age, sex, and race using AI-based quantification algorithm
The Agatston score is commonly used for coronary artery calcium (CAC) quantification which integrates calcium volume and density into a single measure. Recent studies suggest CAC volume and mean density offer independent prognostic value. However, normative distributions of these parameters across demographic subgroups are not well characterized.

The Utility Of “Thinking” In CAD-RADS Scoring Of An Open-source Hybrid-reasoning Large Language Model: A Multicentric Study
Introduction: Large language models (LLMs) are developed to answer questions or follow instructions like humans do. New LLMs are introduced frequently. It is essential to benchmark the performance of current LLMs for clinical purposes. Our goal was to benchmark the performance of 31 open- and closed-source LLMs in automatically assigning coronary artery disease reporting and data system (CAD-RADS) categories from coronary CT angiography (CCTA) reports, using a zero-shot prompting approach.
