Contrast enhanced ultrasound at first month: A feasible predictor for retreatment after benign thyroid nodule thermal ablation
Benign thyroid nodules (BTNs) are a common occurrence in the population [1]. The estimated prevalence of thyroid nodules in global is as high as 67 %, with nearly 90 % characterized as benign [2]. Clinical interventions typically deemed unnecessary in the majority of BTNs. However, palpable large BTNs necessitate treatment due to nodule-related compressive symptoms or cosmetic concerns [3]. Ultrasound (US)-guided thermal ablation (TA), encompassing modalities such as radiofrequency ablation (RFA…

Head position matters: Position‑dependent vestibular flow void artifacts in inner ear MRI and their clinical implications
It has been shown that static magnetic fields from high-strength magnetic resonance imaging (MRI) machines induce nystagmus in all humans with intact inner ear function. This effect can be explained by the magneto-hydrodynamic Lorentz force, which arises from the interaction of endolymphatic ionic currents and the strong static magnetic field of an MRI machine. Prior experiments demonstrated that MRI-induced nystagmus and vertigo vary with head pitch relative to the magnetic field, being reduced…

Quantitative airway evaluation using supine and upright computed tomography in patients with non-cystic fibrosis bronchiectasis and nontuberculous mycobacterial pulmonary disease
Globally, the incidence of nontuberculous mycobacterial (NTM) disease has increased in recent years [1,2], surpassing that of tuberculosis in Japan [3]. Nontuberculous mycobacterial pulmonary disease (NTM-PD) typically manifests as a slowly progressive disease with a significant impact on health-related quality of life [4] and mortality [5]. Radiologic evaluations, including high-resolution computed tomography (HRCT), play a crucial role in the diagnosis, management, and understanding of disease…

Magnetic resonance imaging of penile Prostheses: A pictorial review of normal appearances and complications
Erectile dysfunction (ED) is the persistent or recurrent inability to achieve and maintain an erection sufficient for satisfactory sexual relations, affecting an estimated 30–50 % of men aged 40–70 years [1,2]. For patients who have failed conservative management or are ineligible for pharmacological therapies, penile prosthesis implantation represents a definitive treatment option with high satisfaction rates [3–5].

Clarifying the practical interpretation of the CAD-RADS “N” modifier in routine coronary CT angiography
We read with great interest the recent article published in the European Journal of Radiology evaluating the diagnostic performance of AI-assisted coronary CT angiography for CAD-RADS classification. This work highlights ongoing efforts to improve the consistency, reproducibility, and clinical usability of CAD-RADS in routine practice, including emerging automated and AI-assisted reporting workflows.

ChatGPT-generated informed consent forms in interventional radiology: A randomized controlled evaluation of comprehension, attitudinal responses, and readability
Informed consent is both an ethical and legal requirement in clinical medicine, ensuring that patients receive adequate, comprehensible information before undergoing diagnostic or therapeutic procedures [1]. However, in practice, many consent documents in interventional radiology are written at a linguistic complexity far beyond the average patient’s comprehension level. The use of complex medical jargon and long, unstructured explanations often leads to suboptimal comprehension and passive cons…

Unveiling risk factors for transient osteoporosis of the hip in Middle-Aged Men: Insights from a Cross-Sectional study
Transient osteoporosis of the hip (TOH) is an uncommon, self-limiting pain condition of unknown origin, primarily affecting the hip [1]. It was first described by Curtis and Kincaid in 1959 in women during the third trimester of pregnancy or the peripartum period [2]. Later the disease was characterized in middle-aged males (4th-6th decade) in which, TOH is reported to be threefold more prevalent compared to females [3]. The clinical manifestation of TOH is characterized by spontaneous, abrupt h…

Role of magnetic resonance imaging in evaluation of urogenital sinus malformations
Persistent urogenital sinus (UGS) is a rare but complex congenital anomaly that poses significant challenges in pediatric reconstructive surgery. Accurate preoperative visualization of the urogenital anatomy is essential for optimal surgical planning. This study aims to evaluate the diagnostic utility of magnetic resonance imaging (MRI) in assessing persistent UGS, specifically the site of confluence, common channel length, urethral length, and to correlate MRI findings with the preoperative cys…

A novel and general spatiotemporal diagnostic model: Intratumoral outflow and peritumoral inflow for the differentiation and stratification of breast tumor
A simplified schematic of proposed IOPI model with the progression of intravasation and extravasation.Note: In low invasive breast cancer, tumor cells (labeled in red) can be seen beginning to accumulate in the ducts, but have not yet broken through the basement membrane, and the invasiveness is relatively low. Whereas in highly invasive breast cancer, tumor cells proliferate in large numbers, break through the basement membrane and invade into the surrounding tissues, showing a stronger degree …
