Flexible and wireless metasurface coils for knee and elbow MRI.
Eur Radiol Exp
January 2025
Department of Diagnostic and Interventional Radiology, Hannover Medical School, Hannover, Germany.
Background: Metasurface coils (MCs) are a promising magnetic resonance imaging (MRI) technology. Aiming to evaluate the image quality of MCs for knee and elbow imaging, we compared signal-to-noise ratio (SNRs) obtained in standard clinical setups.
Methods: Knee and elbow MRI routine sequences were applied at 1.

CT-guided C1-C2 facet joint injections are a valuable tool for managing cervicogenic headaches caused by degenerative and inflammatory conditions of the atlantoaxial joint. This video article presents the procedural technique for a CT-guided C1-C2 facet joint injection in a patient with left-sided cervicogenic headache. Despite concerns regarding potential complications such as vascular injury to the vertebral artery and nerve injury to the C2 dorsal root ganglion, careful anatomic planning and imaging guidance allows safe and effective treatment.

Department of Medical Imaging, Radboud Institute for Health Sciences, Radboud University Medical Center, Geert Grooteplein 10, 6525 GA Nijmegen, The Netherlands.
Purpose: To investigate the feasibility and safety of MRI-guided focal laser ablation (FLA) in localized, International Society of Urological Pathology (ISUP) grade 1-3, prostate cancer (PCa) using an integrated system.
Methods: Ten consecutive males (mean age: 66±7 years) with low-to-intermediate risk PCa were prospectively included (April 2022-May 2023) and treated with MRI-guided FLA using an integrated system for laser energy control and MR thermometry monitoring. Primary endpoints were technical success, procedure-related adverse events (AEs) following SIR (Society of Interventional Radiology) classification, and 12-months local tumor progression-free survival (LTPFS), defined as no evident residual/ recurrent disease on follow-up imaging or histopathology at the treatment site.
Improving care in elderly neurosurgery initiative guideline on management of chronic subdural haematoma in older people-relevance for the geriatrician.

North Bristol NHS Trust - Geriatric Medicine, Southmead Hospital, Southmead Road, Bristol BS10 5NB, UK.
Chronic subdural haematoma (cSDH) is a common subtype of traumatic brain injury, typically affecting older people living with frailty and multimorbidity. Until now, no published guideline has existed internationally to guide management, perhaps explaining why the care of the older cSDH patient varies between neurosurgical centres. The Improving Care in Elderly Neurosurgery Initiative guideline is the first guideline dedicated to the care of patients with cSDH across the entire patient pathway, from initial presentation through to rehabilitation and discharge after surgery.

This study aims to demonstrate the effect of gamma knife radiosurgery (GKRS) on symptoms, hemorrhage rates, and histopathological changes in patients with cavernous malformations (CMs), regardless of whether the symptomatic lesions are hemorrhagic. This single-center retrospective study evaluated symptomatic patients with single CMs treated with GKRS between 2016 and 2023. The patients' demographic data, presenting symptoms, GKRS radiation dose, complications developed during follow-up (hemorrhage, radiotoxicity), the rate of symptom improvement, and histopathological changes of surgically removed CMs were recorded.
