The aim was to predict survival of glioblastoma at 8 months after radiotherapy (a period allowing for completing a typical course adjuvant temozolomide), by applying deep learning the first brain MRI completion.
Increasing age is the biggest risk factor for dementia, of which Alzheimer’s disease commonest cause. The pathological changes underpinning are thought to develop at least a decade prior onset symptoms. Molecular positron emission tomography and multi-modal magnetic resonance imaging allow key processes cognitive impairment – including β-amyloid depostion, vascular disease, network breakdown atrophy be assessed repeatedly non-invasively. This enables potential determinants dementia...
Abstract INTRODUCTION The Centiloid scale aims to harmonize amyloid beta (Aβ) positron emission tomography (PET) measures across different analysis methods. As Centiloids were created using PET/computerized (CT) data and are influenced by scanner differences, we investigated the transformation with from Insight 46 acquired PET/magnetic resonanceimaging (MRI). METHODS We transformed standardized uptake value ratios (SUVRs) 432 florbetapir PET/MRI scans processed whole cerebellum (WC) white...
Objective To summarise the incidental findings detected on brain imaging and blood tests during first wave of data collection for Insight 46 study. Design Prospective observational sub-study a birth cohort. Setting Single-day assessment at research centre in London, UK. Participants 502 individuals were recruited from MRC National Survey Health Development (NSHD), 1946 British cohort, based pre-specified eligibility criteria; mean age was 70.7 (SD: 0.7) 49% female. Outcome measures Data...
Abstract Tuberculous meningitis (TBM) is the most lethal form of tuberculosis. Clinical features, such as coma, can predict death, but they are insufficient for accurate prognosis other outcomes, especially when impacted by co-morbidities HIV infection. Brain magnetic resonance imaging (MRI) characterises extent and severity disease may enable more prediction complications poor outcomes. We analysed clinical brain MRI data from a prospective longitudinal study 216 adults with TBM; 73 (34%)...
ABSTRACT Purpose The Centiloid scale provides a systematic means of harmonising amyloid-β PET measures across different acquisition and processing methodologies. This work explores the transformation [ 18 F]florbetapir data acquired on combined PET/MR scanner processed with methods that differ from standard pipeline. Methods Standard PiB Florbetapir Calibration datasets were using standardised uptake value ratio (SUVR) pipeline MRI parcellations Geodesic Information Flow (GIF) algorithm in...
Abstract Introduction Tuberculous meningitis (TBM) leads to high mortality, especially amongst individuals with HIV. Predicting the incidence of disease-related complications is challenging, for which purpose value brain magnetic resonance imaging (MRI) has not been well investigated. We used a convolutional neural network (CNN) explore contribution MRI conventional prognostic determinants. Method data from two randomised control trials HIV-positive and HIV-negative adults clinical TBM in...
Abstract Background Determining Aβ‐PET status is crucial for Alzheimer’s disease trials. Standard uptake value ratio (SUVR) using a reference region common semi‐quantitative technique. Sex differences in regional blood flow and white matter (WM) could impact SUVR differentially depending on the region. It important to understand how methodological factors can influence derived Aβ status. Method Individuals from Insight 46 (1946 British birth cohort) underwent PET/MR scanning with...
