Functional magnetic resonance imaging

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Functional Magnetic Resonance Imaging (fMRI) is a method of brain magnetic resonance imaging. Unlike in regular magnetic resonance imaging (MRI), which looks at the brain at rest, fMRI is conducted while the patient is performing a cognitive task, in order to identify differences in blood flow related to the cognitive task.

ME/CFS fMRI evidence[edit | edit source]

Cost and availability[edit | edit source]

The University of Michigan, US, current rate for 2018 is $563 per hour.[5]

Specialized training is necessary to operate an fMRI and at this time are rarely used outside of research settings.[6][7] However, it has a "small but growing role in clinical neuroimaging. It is used in pre-surgical planning to localise brain function."[8]

Commercial use[edit | edit source]

Two companies in North America have set up lie detection services and several neuromarketing companies are using fMRI "to gain insights into consumer thought and behaviour."[8]
