Plain English Summary
Background & Aims
The gold standard technique for non-invasive measurement of liver fat has previously been Magnetic Resonance Spectroscopy. This tool is largely confined to the research setting as it requires high energy scanners which are resource intensive. Chemical Shift Magnetic Resonance (CS-MR) poses an alternative which is more applicable in the clinical setting as it can be used on conventional clinical Magnetic Resonance scanners. The accuracy with which CS-MR can repeatedly measure liver fat levels has not previously been assessed. This study aims to assess liver fat levels by using CS-MR in 10 patients on two occasions separated by a minimum of 24 hours. In this time, actual liver fat levels will not have changed. Statistical analysis will then be performed to determine the variation in results CS-MR produces between scans in the same patients. This will provide information on whether CS-MR can be used in studies and clinical practice to accurately detect changes in liver fat levels.
Who can participate?
Anybody over the age of 18 years old with a body mass index greater than 25.
What does the study involve?
Each participant is asked to attend Royal Blackburn Hospital on 2 occasions. During the first visit they are asked to provide a blood sample to assess liver function, circulating blood fat levels and sugar level control. The participants also have a short chemical shift magnetic resonance scan. On the second visit 4 weeks later another chemical shift magnetic resonance scan is performed.
What are the possible benefits?
There are no perceived benefits to participants. Travel expenses will be reimbursed.
When is the study starting?

Scientific title
A precision and reproducibility assessment of intra-hepatic fat quantification by chemical shift magnetic resonance
Acronym

Study hypothesis
The aim of the study is to determine if chemical shift magentic resonance provides a precise and reproducible method of quantifiying intra-hepatic fat fraction using a clinical magentic resonace scanner.
Null Hypothesis:
1. There is no agreement between repeated quantifications of intra-hepatic fat fraction as measured by chemical shift magnetic resonance

Condition
1. Hepatic steatosis or intra-hepatic fat
2. Non alcoholic fatty liver disease
Intervention
10 participants will undergo 2 chemical shift magnetic resonance scans using the clinical magnetic resonance scanner at Royal Blackburn Hospital.
These scans will be performed at least one day apart.
On visit 1, participants will also be asked to provide a blood sample for assessment of liver function, glycaemic control and lipid profile. Weight, height and hip-to-waist ratio will also be recorded. From this body mass index will be calculated.
No further blood samples will be acquired on the second visit.
Intra-person results will be statistically analysed for agreement using the Bland Altmann method with a priori variance levels of 0.2 deemed acceptable.

Primary outcome measures
Intrahepatic fat fraction as measured by 2 Chemical Shift Magnetic Resonance scans greater than 24 hours apart.
Secondary outcome measures
1. Indocyanine Green Plasma Disappearance Rate and Retention at 15 minutes, measured using a PULSiON Indocyanine Green Clearance Testing Device. This will be measured at visit 1 and 4 weeks later
2. BMI, Height, Weight and Hip to Waist ratio, measured at visit 1 and 2
3. Assessment of Liver function, Glycaemic control and Lipid profile, including Bilirubin, AST, ALT, ALP GGT, HbA1c, Random Glucose, Triglycerides and Cholesterol at visit 1.
