c) Frequency:
- Surgical Arm: Scans: Within 4 weeks Prior to surgery, 3-7 days post-operatively; ICG prior to
- SBRT Arm: Within 4 weeks Prior to SBRT, 1 month post SBRT
Clinical Assessments and routine blood tests: Pre-treatment, Post treatment 3-7 days post surgery or 1 month post SBRT), 3 months, 6 months and 12 months post treatment.

2. Indocyanine green (ICG) Test
ICG testing takes 20-minutes and involves insertion of a small needle into the patient's arm and injection of a small volume of a chemical. Small amounts of blood (5ml) will be collected at 5 and 10-minute intervals. Levels of ICG in your blood will be measured by a finger probe.

Imaging Procedures
patient will be injected with 18FDGal as well as MRI Contrast prior to the scan.

Statistical methods / analysis
The dynamic enhancement curves will be extracted from the dynamic Gd-EOB-DTPA MRI and 18FD-Gal PET within each contoured liver subunit. The extracted curves are fitted using a novel model that has been developed to accurately model the physiology of the liver unlike existing approaches which underestimate the blood fraction.The new model accounts for the increased blood flow and rapid extraction of tracers within the liver. The presence of noise within dynamic images can also cause substantial numerical instability when fitting model parameters in addition to the need for motion correction of dynamic images. The HIRF and CSIRO team have addressed this issue using a novel numerical method that exploits the redundancy inherent to the data to ensure robustness and accuracy when fitting biological models with multiple parameters.
Dynamic analysis of MRI and PET images will be undertaken by the medical imaging department at PAH, CSIRO and HIRF. Correlation analysis between galactose metabolism (PET) and hepatobiliary function (MRI) will be performed at the scale of liver segments. The radiation dosimetry will be mapped to the pre- and post-treatment PET/MRI to determine quantitative dose-volume histograms correlating radiation dosimetry to post-treatment function.

Summary
Brief summary
The purpose of this study is to establish a predictive model of liver toxicity using a new MRI and PET scan protocol

Who is it for?
You may be eligible for this study if you are aged 18 or older and have a diagnosis of liver cancer. Your doctor may have recommended for you to undergo surgery or a special type of radiation therapy called Stereotactic Body Radiotherapy (SBRT).

Study details
If you consent to participate, you will be asked to undergo up to two additional scanning sessions involving PET and MRI scans. The first scanning session will be conducted in the weeks prior to your treatment. If your liver tumour is treated with SBRT the second scanning session will be conducted approximately one month following treatment. If your liver tumour is treated with surgery the second scanning session will be conducted in the week following your operation if it is feasible to do so and you have adequately recovered from surgery.

You will be scanned on a PET/MR scanner which will simultaneously acquire PET and MRI images. You are required to fast for at least 4 hours prior to the scan, but you can drink water if required. The scanning sessions take approximately 30-60 minutes between 1 to 2 hours, and you will be in the molecular imaging department for 2-3 hours. Pictures are taken with you lying on the scanner bed with your arms above your head. The bed moves through the scanner which acquires pictures as the bed passes. After the test, you will remain slightly radioactive for the rest of the day, so we recommend that you avoid prolonged contact with children and pregnant women for about 6 hours after the start of the scan.

Scanning sessions may be performed at the Princess Alexandra Hospital or the Herston Imaging Research Facility (HIRF), located on the Royal Brisbane and Women’s Hospital campus.

As part of your usual care you will undergo an indocyanine green (ICG) test which provides the medical team with an estimate of your overall liver function to help them determine your best treatment. As part of this research project you may also be asked to undergo this test again following treatment prior to the second scanning session.

All your medical treatment will be conducted as per usual according to the best possible standard of care as determined by your treating medical team

It is hoped this research will lead to more accurate prediction of liver function after surgery or radiation therapy which could increase the proportion of patients appropriately selected for treatments, and reduce toxicity by protecting parts of the liver.
