The middle ear ossicular ligaments were first comprehensively described in anatomic detail by Wolff and Belluci in 1956 (1). The ossicular ligaments were largely beyond the resolution of medical imaging until the early 1990′s at which time improvements in tube, detector and collimator technology allowed for their visualization (2). Since this early work, more detailed descriptions of these ligaments have been provided using micro-CT scans on stained pathological temporal bone samples, and cadave…

Evaluation of DeepSeek-R1 and contemporary large language models on the radiology board examination: A milestone achieved as open-source model matches performance with closed-source model
The explosive progress of large language models (LLMs) over the last three years has reshaped knowledge-intensive disciplines, including medicine and, increasingly, radiology [1,2]. State-of-the-art proprietary systems such as OpenAI GPT-4 have matched—or even exceeded—human pass rates on medical licensing and specialty examinations, demonstrating that transformer-based models can internalize vast biomedical corpora and recall them with examination-level precision.

Predictive value of quantitative parameters from dual-tracer FDG and PSMA PET/CT for progression to castration resistance in patients with metastatic hormone-sensitive prostate cancer
To explore the prognostic value of dual-tracer PET/CT-derived parameters and develop a predictive model for castration-resistant prostate cancer-free survival (CRPC-FS) in patients with metastatic hormone-sensitive prostate cancer (mHSPC).

A combination of High-Pitch turbo FLASH mode and iterative Beam-Hardening correction in cranial computed tomography Facilitates acute small subdural hematoma visualization
To assess the impact of combined high-pitch turbo FLASH mode and iterative beam-hardening correction (iBHC) on image quality and diagnostic performance for detecting acute small subdural hematoma in brain CT.

Hepatic steatosis can accurately be measured during free breathing using ultrasound-guided attenuation parameter (UGAP) technology. Technical note
Recent data indicates that hepatic steatosis affects 38 % of the global adult population [1,2]. Metabolic dysfunction-associated steatotic liver disease (MASLD) [3,4] is the most common cause of chronic liver disease worldwide, with an all-cause mortality rate nearly double that of the general population [5]. Given the high prevalence of hepatic steatosis, non-invasive methods are greatly preferable for diagnosis and follow-up after treatment.

Usefulness of metal artifact reduction on CT angiography after massive coil embolization in peripheral AVM
Arteriovenous malformation (AVM) is a rare congenital vascular malformation that involves abnormal connections between arteries and veins, with an annual incidence of 0.24 cases per 100,000 population [1,2]. Given that surgical resection is often limited by the complex angioarchitecture and anatomical location of AVMs, transcatheter embolization has evolved as the treatment of choice [3–7]. Due to high recurrence risks, long-term image follow-up is necessary for evaluating treatment response and…

Treatment of non-severe hemoptysis: A retrospective propensity score-matched comparison between conservative management and bronchial artery embolization
Hemoptysis is a common clinical presentation that ranges from minor streaking to life-threatening massive bleeding [1]. The management approaches varies significantly based on severity. For severe hemoptysis, defined as expectorated blood volume totaling 300–600 mL over 24-hours or three or more episodes of 100 mL expectorated blood over three days within one week, surgery was historically considered the treatment of choice, but bronchial artery embolization (BAE) is currently considered to be t…

Automated lung texture analysis for assessing interstitial lung disease in systemic sclerosis: Diagnostic accuracy in photon-counting-detector and conventional energy-integrating-detector CT
Interstitial lung disease (ILD) is a frequent organ manifestation of systemic sclerosis (SSc), a rare but severe autoimmune connective tissue disorder [1]. The pathogenesis involves abnormal immune system activation, injury to endothelial and epithelial cells, and fibroblast activation leading to excessive collagen accumulation and thickening of the skin and internal organs, including the lungs [2]. Pulmonary manifestations remain the leading cause of death in SSc [3]. Early detection and timely…

Safety and performance of a lipiodol-resistant mixing and injection system in conventional trans-arterial chemoembolization: A post-market clinical follow-up
Liver cancer is the sixth most diagnosed cancer and the third leading cause of cancer-related death worldwide. Hepatocellular carcinoma (HCC) represents about 75–85 % of primary liver cancers [1].

Tumor and Perirenal Adipose Tissue Radiomic Models for Pathological T-Stage Prediction and Biological Exploration in Clear Cell Renal Cell Carcinoma
Clear cell renal cell carcinoma (ccRCC) shows a rising incidence and mortality worldwide [1,2]. Guideline-implemented cancer staging systems play an essential role in stratifying patients with tumors, especially in terms of therapeutics, prognostic prediction, postoperative follow-up, and even clinical trials. Notably, the T-stage system has shown great relevance in guiding clinical management decisions for ccRCC [3–5]. Hence, accurately predicting T staging preoperatively is crucial for optimiz…
