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 …

Cumulative dose: A simple infographic for referrers and patients
Communicating radiation risks effectively is critical in imaging examinations, especially for ensuring the benefit-risk justification among radiologists, medical physicists, referrers, radiation technologists, and patients. Imaging modalities such as CT, fluoroscopic interventions, and PET/CT pose challenges due to high cumulative radiation exposure in patients who require recurrent imaging. In recent years there has been a strong emphasis on assessing the cumulative effective doses (CED) in pat…

Relationship between pericoronary fat attenuation index and quantitative plaque components in newly identified coronary plaques
FAI associatied with newly identified plaque components.Fat attenuation index (FAI) interacted with newly identified plaque. Before plaque formation, higher baseline FAI is correlated with plaque volume and components. After plaque formation, necrotic core and fibrous tissue were independent determinants of changes in FAI.

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…

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…

Computed tomography features of gastric cancer with deficient mismatch repair: Radiologic–pathologic correlation
Immunotherapy has emerged as a promising therapeutic approach for locally advanced gastric cancer (LAGC) [1–3]. However, due to variability in patient response to immunotherapy [1], reliable biomarkers are needed for the prediction of patient response before treatment initiation. Recently, research has identified deficient mismatch repair (dMMR) and microsatellite instability-high (MSI-H) as potential predictors of immunotherapy response in patients with LAGC [2]. The study by Tran-Minh et al. r…

Education and training satisfaction among radiology residents: Insights from a national survey
Radiology residency programs are shaping the future of radiology by supporting the development of high-quality next generation of radiologists. The satisfaction of radiology residents with their education and training is not only a measure of program effectiveness but also an indicator of the overall quality of radiology training experiences. Understanding the factors contributing to resident satisfaction or discontentment is essential for program directors, educators, and policymakers to enhanc…
