Magnetic resonance imaging. Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the organs in the body.
The BOLD signal that underlies most fMRI applications is essentially a qualitative signal, because it depends in a complex way on the combined physiological changes of blood flow and oxygen metabolism. An alternative MRI method called arterial spin labeling (ASL) is a tool for measuring blood flow changes directly.t is not because the MR signal is directly sensitive to the neural activity. Instead, the MR signal change is an indirect effect related to the changes in blood flow that follow the changes in neural activity.
