Variability of noninvasive MRI and biological markers in compensated cirrhosis: insights for assessing disease progression (2022)
Journal Article

Abstract: Background: We annually monitored stable compensated cirrhosis (CC) patients to evaluate serial variation in blood serum, liver stiffness, and multiparametric magnetic resonance imaging (mpMRI) measures to provide reference change values (R...

Fast Event-Related Mapping of Population Fingertip Tuning Properties in Human Sensorimotor Cortex at 7T (2022)
Journal Article

fMRI studies that investigate somatotopic tactile representations in the human cortex typically use either block or phase-encoded stimulation designs. Event-related (ER) designs allow for more flexible and unpredictable stimulation sequences than the...

Decreased renal perfusion during acute kidney injury in critical COVID-19 assessed by magnetic resonance imaging: a prospective case control study (2022)
Journal Article

Abstract: Background: Renal hypoperfusion has been suggested to contribute to the development of acute kidney injury (AKI) in critical COVID-19. However, limited data exist to support this. We aim to investigate the differences in renal perfusion, ox...

LMISA: A Lightweight Multi-modality Image Segmentation Network via Domain Adaptation using Gradient Magnitude and Shape Constraint (2022)
Journal Article

In medical image segmentation, supervised machine learning models trained using one image modality (e.g. computed tomography (CT)) are often prone to failure when applied to another image modality (e.g. magnetic resonance imaging (MRI)) even for the...

Multiparametric magnetic resonance imaging allows non-invasive functional and structural evaluation of diabetic kidney disease (2022)
Journal Article

Background: We sought to develop a novel non-contrast multiparametric MRI (mpMRI) protocol employing several complementary techniques in a single scan session for a comprehensive functional and structural evaluation of diabetic kidney disease (DKD).... Read More about Multiparametric magnetic resonance imaging allows non-invasive functional and structural evaluation of diabetic kidney disease.

Review article: The aetiology of fatigue in inflammatory bowel disease and potential therapeutic management strategies (2021)
Journal Article

Background: Fatigue is the inability to achieve or maintain an expected work output resulting from central or peripheral mechanisms. The prevalence of inflammatory bowel disease (IBD) fatigue can reach 86% in active disease, persisting in 50%-52% of... Read More about Review article: The aetiology of fatigue in inflammatory bowel disease and potential therapeutic management strategies.

Muscle and tendon adaptations to moderate load eccentric vs. concentric resistance exercise in young and older males (2021)
Journal Article

Resistance exercise training (RET) is well-known to counteract negative age-related changes in both muscle and tendon tissue. Traditional RET consists of both concentric (CON) and eccentric (ECC) contractions; nevertheless, isolated ECC contractions...

Comparison of continuous sampling with active noise cancelation and sparse sampling for cortical and subcortical auditory functional MRI (2021)
Journal Article

Purpose Detecting sound-related activity using functional MRI requires the auditory stimulus to be more salient than the intense background scanner acoustic noise. Various strategies can reduce the impact of scanner acoustic noise, including “sparse... Read More about Comparison of continuous sampling with active noise cancelation and sparse sampling for cortical and subcortical auditory functional MRI.

Measuring resting cerebral haemodynamics using MRI arterial spin labelling and transcranial Doppler ultrasound: comparison in younger and older adults (2021)
Journal Article

Introduction: Resting cerebral blood flow (CBF) and perfusion measures have been used to determine brain health. Studies showing variation in resting CBF with age and fitness level using different imaging approaches have produced mixed findings. We a...

Contrasting Measures of Cerebrovascular Reactivity Between MRI and Doppler: A Cross-Sectional Study of Younger and Older Healthy Individuals (2021)
Journal Article

Cerebrovascular reactivity (CVR) is used as an outcome measure of brain health. Traditionally, lower CVR is associated with ageing, poor fitness and brain-related conditions (e.g. stroke, dementia). Indeed, CVR is suggested as a biomarker for disease...

Automated renal segmentation in healthy and chronic kidney disease subjects using a convolutional neural network (2021)
Journal Article

Purpose: Total Kidney Volume (TKV) is an important measure in renal disease detection and monitoring. We developed a fully automated method to segment the kidneys from T2-weighted magnetic resonance images (MRI) to calculate TKV of healthy control (H...

Multiparametric MRI assessment of renal structure and function in acute kidney injury and renal recovery (2021)
Journal Article

Background: Acute Kidney Injury (AKI) is associated with a marked increase in mortality as well as subsequent chronic kidney disease (CKD) and end stage kidney disease. We performed multiparametric MRI with the aim of identifying potential non-invasi...

Circadian variation in renal blood flow and kidney function in healthy volunteers monitored using non-invasive magnetic resonance imaging (2020)
Journal Article

Circadian regulation of kidney function is involved in maintaining whole-body homeostasis and dysfunctional circadian rhythm can potentially be involved in disease development. Magnetic Resonance Imaging (MRI)provides reliable and reproducible repeti...

Effective connectivity of the right anterior insula in schizophrenia: the salience network and task-negative to task-positive transition (2020)
Journal Article

Triple network dysfunction theory of schizophrenia postulates that the interaction between the default-mode and the fronto-parietal executive network is disrupted by aberrant salience signals from the right anterior insula (rAI). To date, it is not c... Read More about Effective connectivity of the right anterior insula in schizophrenia: the salience network and task-negative to task-positive transition.
