Abstract Background Epileptic seizures are an established comorbidity of Alzheimer’s disease (AD). Subclinical epileptiform activity (SEA) as detected by 24-h electroencephalography (EEG) or magneto-encephalography (MEG) has been reported in temporal regions clinically diagnosed AD patients. Although epileptic probably arises the mesial lobe, electrical within this region might not propagate to EEG scalp electrodes and could remain undetected standard EEG. However, SEA lead faster cognitive...

Magnetic Resonance Imaging (MRI) has become part of the clinical routine for diagnosing neurodegenerative disorders. Since acquisitions are performed at multiple centers using imaging systems, detailed analysis brain volumetry differences between MRI systems and scan-rescan can provide valuable information to correct different scanner effects in multi-center longitudinal studies. To this end, five healthy controls patients belonging various stages AD continuum underwent on three (Philips...

Early neurorehabilitation can enhance neurocognitive outcomes in very preterm infants (<32 weeks), and conventional magnetic resonance imaging (MRI) is commonly used to assess neonatal brain injury; however, the predictive value for neurodevelopmental delay limited. Timely quantitative biomarkers are needed improve early identification management of at risk delay.

<h3>BACKGROUND AND PURPOSE:</h3> Neonatal MR imaging brain volume measurements can be used as biomarkers for long-term neurodevelopmental outcome, but quantitative volumetric data are not usually available during routine radiologic evaluation. In the current study, feasibility of automated volumetry and image reconstruction via synthetic in very preterm infants was investigated. <h3>MATERIALS METHODS:</h3> Conventional T1WIs T2WIs from 111 were acquired at term-equivalent age. Overall...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating and degenerative disorder of the central nervous system. Accelerated brain volume loss (BVL) has emerged as promising magnetic resonance imaging marker (MRI) neurodegeneration, correlating with present future clinical disability. We have systematically selected MS patients fulfilling 'no evidence disease activity-3' (NEDA-3) criteria under high-efficacy disease-modifying treatment (DMT) from database two Belgian centers. BVL...

<p class="p1">We report the case of a 41-year-old male with traumatic coronary artery dissection after high-speed motor vehicle collision. Computed tomography imaging revealed multiple intracranial subdural and subarachnoid bleedings, skull base fracture bilateral rib fractures. There was no pericardial hemorrhage, haemothorax or pneumothorax. No intra-abdominal lesions were found. A 12-lead electrocardiogram on arrival showed an acute myocardial infarction. Emergency angiography complete...

Abstract Purpose To assess the performance of inferior lateral ventricle (ILV) to hippocampal (Hip) volume ratio on brain MRI, for Alzheimer’s disease (AD) diagnostics, comparing it individual automated ILV and volumes, visual medial temporal lobe atrophy (MTA) consensus ratings. Methods One-hundred-twelve subjects ( mean age ± SD , 66.85 13.64 years) with varying degrees cognitive decline underwent MRI using a Philips Ingenia 3T. The MTA scale by Scheltens, rated coronal 3D T1-weighted...

To identify preterm infants at risk for neurodevelopment impairment that might benefit from early neurorehabilitation, prognostic biomarkers of future outcomes are needed. determine whether synthetic MRI is sensitive to age-related changes in regional tissue relaxation times the brain born neonates when scanned term equivalent age (TEA, 37–42 weeks), and investigate severe postnatal morbidity results prolonged times. This retrospective study included 70 very with conventional between January...

The novel coronavirus (SARS-CoV-2) causing the recent pandemic outbreak may result in brain injuries. disease has a high prevalence for thromboembolic complications and massive release of cytokines. We report case CLOCCS, one rare neurological SARS-CoV-2 infection.The imaging features cytotoxic lesion corpus callosum (CLOCCS) on magnetic resonance should be known by every radiologist, to make positive diagnosis prevent misdiagnosis, especially setting COVID-19 infection.

Abstract Background Magnetic Resonance Imaging (MRI) has become part of clinical routine for diagnosis neurodegenerative brain disorders. Acquisitions are performed at multiple centers, using imaging systems and is therefore subjected to intra‐ inter‐scanner variability. Detailed analysis volumetry differences between MRI scan‐rescan acquisitions can provide useful information correct different scanner effects in future multi‐center longitudinal studies. Method The study population (n=10)...
