The impact of variations in subject geometry, respiration and coil repositioning on the specific absorption rate in parallel transmit abdominal imaging at 7 T (2023)
Journal Article

Parallel transmit MRI at 7 T has increasingly been adopted in research projects and provides increased signal‐to‐noise ratios and novel contrasts. However, the interactions of fields in the body need to be carefully considered to ensure safe scanning...

Liver glycogen stores via 13C magnetic resonance spectroscopy in healthy children: randomized, controlled study (2023)
Journal Article

Background: Owing to its role in glucose homeostasis, liver glycogen concentration ([LGly]) can be a marker of altered metabolism seen in disorders that impact the health of children. However, there is a paucity of normative data for this measure in... Read More about Liver glycogen stores via 13C magnetic resonance spectroscopy in healthy children: randomized, controlled study.

The effect of acute and chronic exercise on hepatic lipid composition (2023)
Journal Article

Exercise is recommended for those with, or at risk of nonalcoholic fatty liver disease (NAFLD), owing to beneficial effects on hepatic steatosis and cardiometabolic risk. Whilst exercise training reduces total intrahepatic lipid in people with NAFLD,... Read More about The effect of acute and chronic exercise on hepatic lipid composition.

Comparing magnetic resonance liver fat fraction measurements with histology in fibrosis: the difference between proton density fat fraction and tissue mass fat fraction (2022)
Journal Article

Objective: Magnetic resonance spectroscopy (MRS) provides a powerful method of measuring fat fraction. However, previous studies have shown that MRS results give lower values compared with visual estimates from biopsies in fibrotic livers. This study...

Effects of an isoenergetic low Glycaemic Index (GI) diet on liver fat accumulation and gut microbiota composition in patients with non-alcoholic fatty liver disease (NAFLD): A study protocol of an efficacy mechanism evaluation (2021)
Journal Article

Introduction A Low Glycaemic Index (LGI) diet is a proposed lifestyle intervention in non-alcoholic fatty liver diseases (NAFLD) which is designed to reduce circulating blood glucose levels, hepatic glucose influx, insulin resistance and de novo lipo... Read More about Effects of an isoenergetic low Glycaemic Index (GI) diet on liver fat accumulation and gut microbiota composition in patients with non-alcoholic fatty liver disease (NAFLD): A study protocol of an efficacy mechanism evaluation.

The role of hepatic lipid composition in obesity-related metabolic disease (2021)
Journal Article

Obesity is a primary antecedent to non-alcoholic fatty liver disease whose cardinal feature is excessive hepatic lipid accumulation. Although total hepatic lipid content closely associates with hepatic and systemic metabolic dysfunction, accumulating...

Calibration-free regional RF shims for MRS (2021)
Journal Article

Purpose: Achieving a desired RF transmit field (B1+) in small regions-of-interest (ROIs) is critical for single-voxel MR spectroscopy at ultra-high field. RF shimming, using parallel transmission, requires B1+ mapping and optimisation, which limits i... Read More about Calibration-free regional RF shims for MRS.

Metabolic Imaging in Non-Alcoholic Fatty Liver Disease: Applications of Magnetic Resonance Spectroscopy (2021)
Journal Article

Non-alcoholic fatty liver disease (NAFLD) is poised to dominate the landscape of clinical hepatology in the 21st century. Its complex, interdependent aetiologies, non-linear disease progression and uncertain natural history have presented great chall...

Effects of sprint interval training on ectopic lipids and tissue-specific insulin sensitivity in men with non-alcoholic fatty liver disease (2018)
Journal Article

Purpose: This study examined the feasibility of sprint interval exercise training (SIT) for men with non-alcoholic fatty liver disease (NAFLD) and its effects on intrahepatic triglyceride (IHTG), insulin sensitivity (hepatic and peripheral), visceral... Read More about Effects of sprint interval training on ectopic lipids and tissue-specific insulin sensitivity in men with non-alcoholic fatty liver disease.

Current and future magnetic resonance technologies for assessing liver disease in clinical and experimental medicine (2017)
Journal Article

Background: In the past decades, a number of non-invasive methods have emerged for detecting and estimating liver fibrosis; these include both serum-based panels and imaging-based technology. Some of these methods are now being incorporated in clinic... Read More about Current and future magnetic resonance technologies for assessing liver disease in clinical and experimental medicine.

Increased liver fat and glycogen stores after consumption of high versus low glycaemic index food: a randomized crossover study (2016)
Journal Article

Aim: To investigate the acute and longer-term effects of low (LGI) versus high glycaemic index (HGI) diets on hepatic fat and glycogen accumulation and related blood measures in healthy volunteers. Methods: Eight healthy men (age 20.1 � 0.4 years,... Read More about Increased liver fat and glycogen stores after consumption of high versus low glycaemic index food: a randomized crossover study.

Corticotrophin releasing factor increases ascending colon volume after a fructose test meal in healthy humans: a randomised control trial (2016)
Journal Article

Background: Poorly absorbed, fermentable carbohydrates can provoke irritable bowel syndrome (IBS) symptoms by escaping absorption in the small bowel and being rapidly fermented in the colon in some susceptible subjects. IBS patients are often anxious... Read More about Corticotrophin releasing factor increases ascending colon volume after a fructose test meal in healthy humans: a randomised control trial.

Investigating the effects of an oral fructose challenge on hepatic ATP reserves in healthy volunteers: a 31P MRS study (2015)
Journal Article

Background: Impaired homeostasis of hepatic ATP has been associated with NAFLD. An intravenous fructose infusion has been shown to be an effective challenge to monitor the depletion and subsequent recovery of hepatic ATP reserves using 31P MRS. Aims...

A low calorie morning meal prevents the decline of hepatic glycogen stores: a pilot in vivo 13C magnetic resonance study (2014)
Journal Article

Previous studies have reported a meal-induced rise in hepatic glycogen stores from baseline levels following a fast and it is generally assumed that glycogen levels rise steadily following meals throughout the day. However, measurements are normally... Read More about A low calorie morning meal prevents the decline of hepatic glycogen stores: a pilot in vivo 13C magnetic resonance study.
