Plain English summary of protocol
Background and study aims:
There are different types of medical scans that can be used to diagnose tumours (a mass of cells). Diffusion weighted imaging- magnetic resonance imaging (DWI-MRI) is a type of scan that uses the changes of water movement to create an image. 18F-fluorodeoxyglucose Positron Emission Tomography (18F-FDG PET) is a type of scan that uses a small amount of a drug as a tracer (FDG) to show the difference between healthy tissue and diseased tissue. These two different scans show tumour in different ways. Some researchers think DWI-MRI scans can replace 18F-FDG PET scans for diagnosing tumours and that 18F-FDG PET should only be used for certain types of cancers. The aim of this study is to compare different types of imaging to see which one has the best clinical outcomes for diagnosing tumours.
Who can participate?
Adults aged 18-80 who have brain, lung, liver and pancreatic tumour.
What does the study involve?
Participants undergo their standard scan using the 18F-FDG PET/CT scan or the DWI-MRI. Each scan is assessed to see how well it can diagnose tumours.
What are the possible benefits and risks of participating?
There are no notable benefits or risks with participating.
