The wall instability of unruptured intracranial aneurysms (UIAs) is associated with aneurysm growth or rupture. The wall shear stress (WSS) of 4D-flow-MRI can indicate hemodynamic abnormalities on the aneurysm wall. Aneurysm wall enhancement (AWE) of vessel wall MRI (VWI) and volume transfer constant (Ktrans) of dynamic contrast-enhanced MRI (DCE-MRI) can indicate inflammation and permeability changes of the unstable aneurysm wall. We hypothesize that the WSS of UIAs is not only associated with …

Integrating Large language models into radiology workflow: Impact of generating personalized report templates from summary
The advent of large language models (LLMs) has revolutionized various fields, including healthcare, within a remarkably short span of time [1,2]. In the two years since their launch, numerous models have emerged, each more sophisticated than the last [3]. These models have been applied across a wide array of use cases, demonstrating their versatility and potential. From generating human-like text to aiding in complex decision-making processes, LLMs have become invaluable tools in industries rang…

The ACR Learning Network Recommendations Follow-Up Improvement Collaborative: Ensuring Quality Surveillance of Pulmonary Nodules
To share findings from the first two cohorts of the ACR Learning Network Recommendations Follow-Up Improvement Collaborative. The collaborative targets safe, high-quality practice in the follow-up of incidental pulmonary nodules. Participating sites had the shared goal of improving (i) recommendation adherence to the Fleischner Society Guidelines and (ii) follow-up imaging completion rates.

Allergological evaluation of hypersensitivity reactions after administration of contrast agents: What the radiologist needs to know
Contrast agents (CA) are drugs used in diagnostic and therapeutic radiological procedures. Diverse types of CA are used to perform various radiological techniques. Although in some situations a same CA may be used across multiple techniques, they are generally associated with a specific type of imaging: iodine-based contrast media (ICM) for X-ray examinations, gadolinium-based contrast agents (GBCA) for magnetic resonance imaging, and microbubble ultrasound contrast agents (USCA) for ultrasound …

The predictive value of 18F-FDG PET/CT radiomics for pleural invasion in non-small cell lung cancer
Lung cancer is one of the most prevalent malignant tumors globally and is associated with a high mortality rate, with NSCLC comprising approximately 80 % of all cases[1]. Surgical resection remains the preferred treatment for patients with early-stage NSCLC. However, the recurrence rate following surgical resection remains substantial. PI in NSCLC is an independent predictor of poor prognosis and is directly related to the choice of surgical approach[2–4].For lung cancer nodules smaller than 3 c…

Anatomically indexed aortic valve calcium score more accurately predicts transaortic peak velocities and gradients compared to radiomics features in patients with severe aortic stenosis
This study examines the use of computed tomography (CT)-derived calcified and non-calcified aortic valve (AV) features, including radiomics-based quantitative imaging biomarkers, for predicting aortic stenosis (AS) severity and evaluating sex-specific differences.

Can a Six-Minute MRI Facilitate Detection of Multiple Sclerosis?
Recognition of the central vein sign with a six-minute MRI demonstrated comparable sensitivity for multiple sclerosis (MS) detection in comparison to oligoclonal band (OCB) assessment, which requires lumbar puncture, according to newly published research.
