Clinical Trial Summary

The aim of this study is to develop techniques for non-invasive imaging of biology in participants with benign or malignant renal masses based on the novel scanning MRI techniques, including recently invented Hyperpolarised MRI, deuterium metabolic imaging and sodium MRI. This imaging study will: 1) acquire imaging data from human tissues following the injection of hyperpolarised 13C pyruvate and use 13C-MRI to monitor changes in the ratio of 13C-lactate to 13C-pyruvate; 2) acquire imaging data from human tissues using Sodium MRI or 3) acquire imaging data from human tissues following the oral consumable of deuterated glucose. Data acquired during this physiological study will be used to optimise future imaging protocols.In the UK and possibly in other countries, there are some patients with renal masses that are over treated or undergo unnecessary procedures such as surgery or biopsies, as they are thought to have a malignant tumour or a more aggressive tumour but after the procedure it is found that the mass was benign. The aim of this study is to determine whether one or all of these imaging techniques can differentiate between benign and malignant renal masses with the view to developing the techniques further and hopefully reducing the need for over treatment or unnecessary procedures in patients with benign masses.

Related Conditions & MeSH terms

• Kidney Cancer
• Kidney Neoplasms

Intervention

Device:
• Hyperpolarised MRI
Hyperpolarised 13C-pyruvate injection while laying in the MRI scanner. Non-radioactive, no risk, approved for use in humans.
• Sodium MRI
MRI procedure as a regular MRI scan, the only change is us using a different sort of equipment so we are able to detect sodium.
• Deuterium metabolic imaging (DMI) MRI
Drink of a sugar drink 90min before the MRI scan. Non-radioactive, no risk, approved for use in humans.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	LAC/PYR ratio	LAC/PYR ratio in renal tumours, which is a quantitative measure of conversion from pyruvate to lactate in the tissue of interest.	1 year
Primary	Total Sodium Concentration	Total Sodium Concentration - in renal tumours	1 year
Primary	Technical development of DMI in the abdomen	Detection of metabolites within the DMI spectrum in the abdomen is limited by large lipid peaks and variability of tissues. Therefore, this work will aim to improve acquisition and processing methods to develop abdominal DMI with the hope to evaluate lactate across renal tumour subtypes.	1 year
