FMRI has long been a useful research tool, providing indirect indications of relative change in brain activity when the subject is presented with different stimuli. It has rarely been used in diagnostics as it does not produce numerical data. Currently, positron emission tomography (PET) scans are used to provide quantitative measurements of blood flow and volume in the brain for use in diagnosis. However, PET is expensive, has poor spatial resolution and exposes the patient to ionising radiation.
