Magnetic resonance imaging (mri) is a diagnostic procedure that uses a combination of a large magnet, radiofrequencies, and a during functional resonance imaging of the brain, you will be asked to perform a specific task, such as recite the pledge of allegiance, while the scan is being done.
Magnetic resonance imaging of the brain - Wikipedia from upload.wikimedia.org This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. Magnetic resonance imaging (mri) of the head is a painless, noninvasive test that produces detailed images of your brain and brain stem.

In this, we want to classify an mri scan of a patient's brain obtained in the axial plane as whether there is a presence of tumor or not. Magnetic resonance imaging (mri) uses powerful magnetic fields and radio wave energy to take pictures of the inside of an object.
