Article Abstract
Background And Objective: Epilepsy affects approximately 50 million people worldwide, with 30-40% of patients not responding to medication, necessitating alternative therapies such as surgical intervention. However, the accurate localization of epileptogenic lesions, particularly in pediatric magnetic resonance imaging (MRI)-negative drug-resistant epilepsy, remains a challenge. This paper reviews advanced neuroimaging techniques aimed at improving the detection of such lesions to enhance surgical outcomes.
Methods: A comprehensive literature search was conducted using PubMed, focusing on advanced MRI sequences, focal epilepsy, and the integration of artificial intelligence (AI) in the diagnostic process.
Key Content And Findings: New MRI sequences, including magnetization prepared 2 rapid gradient echo (MP2RAGE), edge-enhancing gradient echo (EDGE), and fluid and white matter suppression (FLAWS), have demonstrated enhanced capabilities in detecting subtle epileptogenic lesions. Quantitative MRI techniques, notably magnetic resonance fingerprinting (MRF), alongside innovative post-processing methods, are emphasized for their effectiveness in delineating cortical malformations, whether used alone or in combination with ultra-high field MRI systems. Furthermore, the integration of AI in radiology is progressing, providing significant support in accurately localizing lesions, and potentially optimizing pre-surgical planning.
Conclusions: While advanced neuroimaging and AI offer significant improvements in the diagnostic process for epilepsy, some challenges remain. These include long acquisition times, the need for extensive data analysis, and a lack of large, standardized datasets for AI validation. However, the future holds promise as research continues to integrate these technologies into clinical practice. These efforts will improve the clinical applicability and effectiveness of these advanced techniques in epilepsy management, paving the way for more accurate diagnoses and better patient outcomes.

Epiduroscopy in spinal stenosis. Description of the procedure and safety measures to reduce complications.
Pain Manag
September 2025
Pain Management Unit, Hospital Universitario Quirónsalud Madrid, Madrid, Spain.
Aims: The aim of this observational study is to describe the use of epiduroscopy to decrease the enlargement of the ligamentum flavum (LF) in patients with spinal stenosis, as well as the selection of the appropriate patient and the safety measures that enhance procedural success.
Materials & Methods: We introduce the patient selection protocol, define the appropriate indication and the safety measures to use the epiduroscopy as a tool to decrease the size of the LF and increase space, reducing possible complications.
Results: Among patients included in the study, there were no cases of access difficulty or coccydynia, and one case of urinary incontinence occurred in a patient with Schizas grade D (very severe) stenosis.
Chikungunya infection complicated by encephalitis and rhabdomyolysis.

Chikungunya virus (CHIKV) typically causes febrile illness and arthralgia. However, severe complications such as encephalitis, rhabdomyolysis, and multiorgan dysfunction are increasingly recognised, particularly during epidemics in endemic regions. We report a case of a 61-year old male presenting with progressive flaccid paraparesis and respiratory failure following febrile illness.

JAMA Neurol
September 2025
Department of Radiology, University of Washington, Seattle.
Importance: Recent longitudinal studies in patients with unruptured intracranial aneurysms (UIAs) suggested that aneurysm wall enhancement (AWE) on magnetic resonance imaging (MRI) predicts growth and rupture. However, because these studies were limited by small sample size and short follow-up duration, it remains unclear whether this radiological biomarker has predictive value for UIA instability.
Objective: To determine the 4-year risk of instability of UIAs with AWE and investigate whether AWE is an independent predictor of UIA instability.

Background: Electrical impedance myography (EIM) has been proposed as an efficient, non-invasive biomarker of muscle composition in facioscapulohumeral muscular dystrophy (FSHD).
Objective: We investigate whether EIM parameters are associated with muscle structure measured by magnetic resonance imaging (MRI), muscle histology, and transcriptomic analysis as well as strength at the individual leg muscle level.
Methods: We performed a multi-center cross-sectional study enrolling 33 patients with FSHD.
