MR Measures of Small Bowel Wall T2 Are Associated With Increased Permeability (2020)
Journal Article

Background: Increased small bowel permeability leads to bacterial translocation, associated with significant morbidity and mortality. Biomarkers are needed to evaluate these changes in vivo, stratify an individual's risk, and evaluate the efficacy of...

Measurement of fasted state gastric antral motility before and after a standard bioavailability and bioequivalence 240 mL drink of water: Validation of MRI method against concomitant perfused manometry in healthy participants (2020)
Journal Article

Objective The gastrointestinal environment in which drug products need to disintegrate before the drug can dissolve and be absorbed has not been studied in detail due to limitations, especially invasiveness of existing techniques. Minimal in vivo dat...

Reward Versus Nonreward Sensitivity of the Medial Versus Lateral Orbitofrontal Cortex Relates to the Severity of Depressive Symptoms (2020)
Journal Article

Background The orbitofrontal cortex (OFC) is implicated in depression. The hypothesis investigated was whether the OFC sensitivity to reward and nonreward is related to the severity of depressive symptoms. Methods Activations in the monetary inc...

Age-related differences in myeloarchitecture measured at 7 T (2020)
Journal Article

We have used the magnetisation transfer (MT) MRI measure as a primary measure of myelination in both the grey matter (GM) of the 78 cortical automated anatomical labelling (AAL) regions of the brain, and the underlying white matter in each region, in...

Feasibility Study of a New MRI Mini-Capsule Device to Measure Whole Gut Transit Time in Pediatric Constipation (2020)
Journal Article

Objective: In England, 27,500 children are referred annually to hospital with constipation. An objective measure of whole gut transit time (WGTT) could aid management. The current standard WGTT assessment, the X-ray radiopaque marker (ROM) test, give...

Processing Apples to Puree or Juice Speeds Gastric Emptying and Reduces Postprandial Intestinal Volumes and Satiety in Healthy Adults (2020)
Journal Article

Background: Whole apples produce greater satiety than processed apples, but the underlying mechanisms remain unclear. Objective: Our aim was to assess the intragastric processing of apple preparations and the associated small and large bowel conten...

Assessing the impact of posture on diaphragm morphology and function using an open upright MRI system – a pilot study (2020)
Journal Article

Purpose The diaphragm is the most important muscle of respiration. Disorders of the diaphragm can have a deleterious impact on respiratory function. We aimed to evaluate the use of an open-configuration upright low-field MRI system to assess diaphra...

The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge (2020)
Journal Article

Background Magnetic resonance imaging (MRI) of the colonic response to a macrogol challenge drink can be used to assess the mechanisms underlying severe constipation. We measured the intra-subject reproducibility of MRI measures of colonic funct... Read More about The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge.

Development of Disordered Eating Behaviors and Comorbid Depressive Symptoms in Adolescence: Neural and Psychopathological Predictors (2020)
Journal Article

BACKGROUND: Eating disorders are common in adolescence, devastating and strongly comorbid with other psychiatric disorders. Yet, little is known about their etiology to develop effective preventive measures. METHODS: Longitudinal assessments of...

The haemodynamics of the human placenta in utero (2020)
Journal Article

© 2020 Dellschaft et al. We have used magnetic resonance imaging (MRI) to provide important new insights into the function of the human placenta in utero. We have measured slow net flow and high net oxygenation in the placenta in vivo, which are cons... Read More about The haemodynamics of the human placenta in utero.

Neural correlates of the dual pathway model for attention-deficit/hyperactivity disorder in adolescents (2020)
Journal Article

Objective: The dual-pathway model has been proposed to explain the heterogeneity in symptoms of attention deficit hyperactivity disorder (ADHD) by two independent psychological pathways based on distinct brain circuits. The authors sought to test... Read More about Neural correlates of the dual pathway model for attention-deficit/hyperactivity disorder in adolescents.

Neurobehavioural characterisation and stratification of reinforcement-related behaviour (2020)
Journal Article

Reinforcement-related cognitive processes, such as reward processing, inhibitory control and social-emotional regulation are critical components of externalising and internalising behaviours. It is unclear to what extent the deficit in each of these... Read More about Neurobehavioural characterisation and stratification of reinforcement-related behaviour.

Simultaneous measurement of gastric emptying of a soup test meal using MRI and gamma scintigraphy (2020)
Journal Article

Measurement of gastric emptying is of clinical value for a range of conditions. Gamma scintigraphy (GS) has an established role, but the use of magnetic resonance imaging (MRI) has recently increased. Previous comparison studies between MRI and GS sh...

Cortical thickness and formal thought disorder in schizophrenia: An ultra high-field network-based morphometry study (2020)
Journal Article

Background Persistent formal thought disorder (FTD) is a core feature of schizophrenia. Recent cognitive and neuroimaging studies indicate a distinct mechanistic pathway underlying the persistent positive FTD (pFTD or disorganized thinking), thoug...

Human hippocampal CA3 damage disrupts both recent and remote episodic memories (2020)
Journal Article

Neocortical-hippocampal interactions support new episodic (event) memories, but there is conflicting evidence about the dependence of remote episodic memories on the hippocampus. In line with systems consolidation and computational theories of episod... Read More about Human hippocampal CA3 damage disrupts both recent and remote episodic memories.
