Salivary gland tumors represent a diverse group of neoplasms that account for approximately 3–6 % of head and neck tumors [1]. Among these, the parotid gland is the most frequently involved site, followed by the submandibular and minor salivary glands [2]. These tumors exhibit significant histopathologic heterogeneity, ranging from benign entities such as pleomorphic adenoma to aggressive malignancies including mucoepidermoid carcinoma and adenoid cystic carcinoma [3]. Given their wide spectrum …

Post-myocardial infarction pericarditis: insight from a cardiovascular magnetic resonance study
Post-myocardial infarction pericarditis (PMIP) is a recognized complication of ST-segment elevation myocardial infarction (STEMI), with potential implications for cardiac function as a marker of more extensive myocardial damage [1]. PMIP can be classified into two distinct forms: early (epistenocardic) pericarditis, which develops within days of infarction due to local inflammatory responses, and late pericarditis (Dressler’s syndrome), which occurs as an autoimmune reaction [2]. The pathophysio…

Superior diagnostic performance of high frame rate Contrast-Enhanced ultrasound (HiFR-CEUS) for small focal liver lesions (≤3 cm): A multicenter study
To evaluate the diagnostic efficacy of high frame rate contrast enhanced ultrasound (HiFR-CEUS) for focal liver lesions (FLLs) of different sizes, particularly for lesions ≤ 3 cm.

Cardiovascular magnetic resonance in Myocarditis: Insights into Diverse clinical presentations
Myocarditis is characterized by inflammation of the myocardium and is known for its heterogeneous clinical presentation and outcome [1–5]. The course of the disease varies, ranging from full recovery to a spectrum of serious cardiac complications, including dilated cardiomyopathy, heart failure, recurrent myocarditis, ventricular arrhythmias, and sudden cardiac death [6–10]. This variability underscores the urgent need for effective risk stratification tools to guide clinical decision-making. Id…

Quantitative MRI iron load assessment in β-thalassemia patients beyond the liver and heart: A systematic review
β-Thalassemia remains a significant global health burden, with an estimated 80–90 million carriers worldwide. The highest prevalence of β-thalassemia is observed in the Mediterranean, Middle East, South Asia, and Southeast Asia, where annual births of affected individuals exceed 60,000 [1]. Iron overload represents a detrimental impact in patients with β-thalassemia, arising predominantly from chronic transfusion therapy and ineffective erythropoiesis. The pathological accumulation of iron withi…

Improved image quality and dose reduction in liver CT using deep learning-based reconstruction: A comparative study
Radiation exposure has notably risen in recent decades, primarily driven by the extensive use of computed tomography (CT) [1,2]. Several studies have pointed out a potential correlation between exposure to medical radiation and an increased risk of cancer, particularly in patients undergoing follow-up care for malignancies [3]. It is crucial to ensure that each CT scan is designed to minimize radiation dose while still obtaining the necessary diagnostic data, following the ALARA (As Low As Reaso…

Extended treatment in cerebral ischemia score 2c or 3 will be goal of successful endovascular treatment: A systematic review and meta-analysis
Multiple randomized controlled trials (RCTs) have demonstrated that endovascular thrombectomy (EVT) is effective in reducing disability in patients with acute ischemic stroke and large vessel occlusion (LVO) [1–8]. The 2013 international consensus established the modified Thrombolysis in Cerebral Infarction (mTICI) scale as the standard for evaluating post-endovascular thrombectomy (EVT) reperfusion, based on its superior inter-rater reliability and predictive validity for clinical outcomes. Whi…

Emergency Radiology: Organizational Models in Swiss and Nordic Hospitals
In the past forty years, emergency radiology (ER) has established itself as a distinct subspeciality, following the development of emergency medicine in medical centers[1]. The initiative to establish ER as a distinct subspecialty, embedded within the emergency department, originated in the 1980s in the United States and subsequently spread to Europe in the 2000s[2]. This initiative stemmed from the recognition that early and efficient management of critically ill patients is closely associated …

Deep learning–reconstructed time-maximum intensity projection versus iterative reconstruction for collateral assessment in acute anterior circulation ischemic stroke
To evaluate the deep learning-reconstructed time-maximum intensity projection (DLR t-MIP) in acute patients with anterior circulation ischemic stroke, and to compare its ability to assess collateral circulation and predict 90-day outcomes with that of single-phase CTA (SP-CTA), multiphase CTA (MP-CTA), and CT perfusion (CTP) volumetrics.

MRI edema patterns in acute neck infections: A multicenter and multidisciplinary interobserver study
Acute infections of neck soft tissues are a medical emergency marked by a high risk of complications, often requiring prompt diagnosis and treatment [1]. Recent studies have established magnetic resonance imaging (MRI) as a feasible primary imaging modality for diagnosing these conditions [2,3]. Due to its exceptional soft tissue contrast, MRI provides superior diagnostic accuracy over the commonly used contrast-enhanced computed tomography (CECT) [4,5]. This capability allows precise identifica…
