1. The study aims to determine whether measures of inflammation have an impact on clinical management. This could be achieved by comparing treatment decisions made by clinicians when ADC, FF and contrast uptake information is available compared to when it is not in a 'virtual clinic'. Whether the scans are available will be determined at random (NB: As this this in a virtual clinic environment it will have no impact on patients' actual management). WB-MRI may be of particular value in this regard, as it has the potential to reveal inflammation in joints which the patient or clinician is not aware of.
