PURPOSE: Aging and increased burden of cardiovascular risk factors are associated with severity of white matter hyperintensity (WMH). We assessed the burden and risk factor profile of WMHs in South Asian patients with transient ischemic attack (TIA) and minor stroke. METHODS: Patients with acute ischemic stroke with the National Institute of Health stroke scale (NIHSS) score 8 or more was considered moderate-severe involvement. Logistic regression analysis was performed to assess the association...

PURPOSE: Various software applications offer support in the diagnosis of acute ischemic stroke (AIS), yet it remains unclear whether the performance of these tools is comparable to each other. Our study aimed to evaluate three fully automated software applications for Alberta Stroke Program Early CT (ASPECT) scoring (Syngo.via Frontier ASPECT Score Prototype V2, Brainomix e-ASPECTS(R) and RAPID ASPECTS) in AIS patients. METHODS: Retrospectively, 131 patients with large vessel occlusion (LVO) of ...

STUDY DESIGN: Prospective experimental uncontrolled trial. BACKGROUND: Lumbar microinstability (MI) is a common cause of lower back pain (LBP) and is related to intervertebral disc degeneration that leads to inability to adequately absorb applied loads. The term "microinstability" has recently been introduced to denote a specific syndrome of biomechanical dysfunction with minimal anatomical change. Trans-facet fixation (TFF) is a minimally invasive technique that involves the placement of screws...

PURPOSE: We aim to illustrate the diagnostic performance of diffusional kurtosis imaging (DKI) in the diagnosis of gliomas. METHODS: A review protocol was developed according to the (PRISMA-P) checklist, registered in the international prospective register of systematic reviews (PROSPERO) and published. A literature search in 4 databases was performed using the keywords 'glioma' and 'diffusional kurtosis'. After applying a robust inclusion/exclusion criteria, included articles were independently...

PURPOSE: Silent new ischemic cerebral lesions (sNICL) detected by diffusion-weighted imaging (DWI) are common after carotid artery stenting (CAS). As part of the Revascularization of Extracranial Carotid Artery Stenosis (RECAS) study, this work aimed to determine predictors of sNICL detected by DWI following CAS. METHODS: A total of 694 patients eligible for the RECAS study treated in Xuanwu Hospital, Capital Medical University, with complete imaging data were included in this retrospective stud...
Cervical nerve root infiltrations are frequently performed in patients with radiculopathy, and computed tomography (CT) is commonly used for image guidance. With the traditional anterolateral approach, catastrophic side events due to spinal ischemia have been reported. To minimize risk, a dorsal approach has been advised, but the safety of this dorsal approach has not been studied systematically. In a 5-year period, 137 cervical nerve root infiltrations using a dorsal approach were performed on ...

The spinal cord (SC) is a dense network of billions of fibers in a small volume surrounded by bones that makes tractography difficult to perform. We aim to provide a review collecting all technical settings of SC tractography and propose the optimal set of parameters to perform a good SC tractography rendering. The MEDLINE database was searched for articles reporting "spinal cord" "tractography" in "humans". Studies were selected only when tractography rendering was displayed and MRI acquisition...

PURPOSE: Magnetic resonance-guided focused ultrasound (MRgFUS) systems are increasingly used to non-invasively treat tremor; consensus on imaging follow-up is poor in these patients. This study aims to elucidate how MRgFUS lesions evolve for a radiological readership with regard to clinical outcome. METHODS: MRgFUS-induced lesions and oedema were retrospectively evaluated based on DWI, SWI, T2-weighted and T1-weighted 3-T MRI data acquired 30 min and 3, 30 and 180 days after MRgFUS (n = 9 essent...

PURPOSE: Although the treatment of intracranial cerebral aneurysms with detachable coils is now widely accepted, the problem of coil compaction and recanalization remains unsolved. If the vessel wall can be regenerated at the neck orifice of an aneurysm, thereby reducing the blood flow into the aneurysm, the recurrence rate of the aneurysm would decrease. Accordingly, we aimed to insert cellulose porous beads (CPBs) into rat models of external carotid artery (ECA) aneurysm and study their effica...

The potential for central nervous system (CNS) involvement in coronavirus disease 2019 (COVID-19) is a matter of grave concern and there is a relevant body of evidence in the basic sciences to support this possibility. A neuroradiologist should be aware of the potential mechanisms involved in the neuropathogenesis of this virus, as we begin to see cases with abnormal brain scans emerging from all parts of the world.
