Contrast agents have diverse functions depending on the imaging technique and clinical examination. In clinical radiology, the importance of contrast media is widely acknowledged for greatly increasing diagnostic confidence across different tissues to precisely identify pathologies [1,2,3,4]. Their mechanism of action relates to their active base components; for instance, those containing gadolinium are mainly used in MRI, while iodine and barium-based agents are employed in fluoroscopy and CT s…

Trump's True Scan Story; School Vax Rates Dropping; Deadly Fungus Spreading
(MedPage Today) — Note that some links may require registration or subscription.
President Donald Trump told the Wall Street Journal that his recent imaging was a CT scan, not an MRI as originally thought, and that there is “nothing wrong” with… -
Can Dual-Energy CT Replace Standard Imaging in GI Bleeding?
A retrospective single-centre study finds that a dual-energy CT protocol is non-inferior to a conventional triphasic CT protocol in diagnosing gastrointestinal bleeding. Medscape News UK

Safety and preliminary efficacy of percutaneous co-ablation system under local anesthesia for the treatment of malignant lung tumors: A retrospective cohort study
Image-guided thermal ablation (IGTA) is a precise, minimally invasive technique that has been widely applied in treating both primary and metastatic lung cancers [1–3]. For patients with early-stage lung cancer who are not surgical candidates, non-surgical local treatments like stereotactic body radiation therapy (SBRT) and IGTA provide tumor control rates comparable to surgery, with a favorable safety profile [4–6]. Radiofrequency ablation (RFA) and microwave ablation (MWA) are the most commonl…

Artificial intelligence performance in image-based biliary atresia identification: a systematic review and meta-analysis
Biliary atresia (BA) is a rare, progressive fibrosclerosing disorder of neonates, characterized by inflammatory obstruction of the extrahepatic and intrahepatic biliary ducts [1–5]. Epidemiological studies report that BA affects approximately 1 in 8000 to 18,000 live births, with a higher prevalence observed among Asian and African populations compared to European cohorts [6]. The incidence varies geographically, with rates reported as 1 in 8000 to 15,000 live births in Japan [7], 1 in 15,000 in…

Advances in the pathogenesis of pulsatile tinnitus induced by sigmoid sinus wall abnormalities: A narrative review
Pulsatile tinnitus (PT) is a common symptom encountered in both otology and neurology, characterized by the perception of rhythmic noise synchronized with the heartbeat [1–3]. Persistent PT can negatively impact both mental and physical health, even leading to functional and structural cerebral changes [4,5]. Based on the underlying causes, PT can be divided into arterial, venous, and neoplastic types, with venous PT being the most prevalent [6–9]. A small sample study reported that among 49 pat…

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.
