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.

Hyperpolarised 13C-pyruvate injection while laying in the MRI scanner. Non-radioactive, no risk, approved for use in humans.
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.
Drink of a sugar drink 90min before the MRI scan. Non-radioactive, no risk, approved for use in humans.

RECRUITINGLAC/PYR ratio
LAC/PYR ratio in renal tumours, which is a quantitative measure of conversion from pyruvate to lactate in the tissue of interest.
Time frame: 1 year
Total Sodium Concentration
Total Sodium Concentration - in renal tumours
Time frame: 1 year
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.
Time frame: 1 year
