Ring-enhancing brain lesions (REBL) represent a significant portion of a neuroradiologist’s daily practice, encompassing both benign and malignant lesions of various origins. REBL encompasses brain abscesses (BA), as well as primary and secondary brain cancers, predominantly metastases and glioblastomas [1]. BA exhibits a prevalence of 0.3–1.3 per ten thousand individuals annually, with a significant incidence of 8 % in underdeveloped nations. BA exhibits a one-year mortality rate of 21 %. This …

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…

Predicting pacemaker dependency after transcatheter aortic valve Replacement: Analysis of ECG, Clinical, and CT-imaging parameters
Severe aortic stenosis is the most common valvular disease in the aging population of the developed world [1]. Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure that has been established as safe and effective for patients across high, intermediate, and low surgical risk categories [2]. Compared to surgical aortic valve replacement (SAVR), TAVR is associated with shorter hospital stays and lower complication rates, contributing to a steady increase in TAVR procedures…

Interchangeable measure of pulmonary regurgitation in repaired tetralogy of Fallot: Comparison between serial cardiac CT and MRI
To identify an interchangeable pulmonary regurgitant measure in repaired tetralogy of Fallot by comparing pulmonary regurgitant volume and fraction between serial cardiac computed tomography (CT) and magnetic resonance imaging (MRI).

Lister’s tubercle revisited: Anatomical variants and tendon relationships on wrist MRI
Lister’s tubercle (LT) is a palpable bony prominence on the distal radius and is in close proximity to the extensor pollicis longus (EPL) tendon. Despite its clinical relevance, detailed knowledge regarding its morphological variations, anatomical relationships, and developmental aspects remains limited. This study aims to evaluate the morphological variants of LT and its anatomical relationships with EPL using wrist magnetic resonance imaging (MRI), and to propose a novel classification system …

Association between MR-derived oxygen extraction fraction and neurological improvement at 24–72 h after successful reperfusion
Oxygen Extraction Fraction (OEF) reflects metabolic changes in cerebral tissue resulting from ischemia and serves as a biomarker of tissue viability in hyperacute stroke. This study evaluated the association between infarct OEF and neurological improvement in ischemic stroke patients following successful endovascular reperfusion therapy, defined by the modified Thrombolysis in Cerebral Infarction (mTICI) score.Infarct OEF index values were extracted from OEF maps using manually delineated infarc…

LI-RADS categories and clinicopathological features predict recurrence-free survival in patients with radical resected hepatocellular carcinoma
To assess the value of LI-RADS categories and clinicopathological characteristics in predicting recurrence-free survival (RFS) after radical resection of hepatocellular carcinoma (HCC).

Four-dimensional computed tomography in expiratory central airway collapse: Disrupting diagnostic paradigms
Expiratory central airway collapse (ECAC) is a pathologic entity that involves the excessive dynamic narrowing of the central airways during the expiratory phase of respiration. ECAC represents a diagnostic challenge for clinicians as patients present with non-specific symptoms such as dyspnea, chronic cough, and recurrent respiratory infections [1]. ECAC comprises of two distinct disorders with similar clinical manifestations but different anatomic locations of collapse: tracheobronchomalacia (…
