It doesn't use radiation like an X-ray or computed tomography (CT) scan, so there's no radiation to worry about. An fMRI scan uses the same MRI machine, but is special because it tracks blood flow in different parts of your brain. Your brain cells use more oxygen when they're working.

In 2022, these promising technologies were joined by the latest additions to the Deep Resolve family. Deep Resolve Boost is an AI-based deep neural network solution leveraging (K-space) raw data-to-image deep learning reconstruction technology that enables high SNR as well as a new level of image acceleration.

On MDsave, the cost of a Functional MRI (fMRI) ranges from $450 to $794. Those on high deductible health plans or without insurance can shop, compare prices and save. Read more about how MDsave works.

Final answer: fMRIs are expensive and may cause discomfort for the patient due to the confinement in the tube-like machine during the procedure. They however provide detailed images because they track blood flow and oxygen levels.
