This change to the underlying structure and chemical makeup of our brains can affect the way we can cope with the normal stresses of life, our productivity, and our overall wellbeing. To do this we use MRI. Physicians are able to tell the difference between various types of tissues based on these magnetic properties. MRI scanners are particularly well suited to image the non-bony parts or soft tissues of the body. Our minds constantly control the flow of information—our memories, thoughts, emotion, and imagination. This spinning motion is known as precession. It is used to advance the understanding of brain organization and offers a potential new standard for assessing neurological status and neurosurgical risk. The hydrogen H atoms are the part that makes water interesting for MRI, and what we use to measure the signal from the body when we do an MRI scan. The stronger the magnetic field, the faster they spin.
This article will provide an introduction to the physics of MR imaging.

Topics in magnetic resonance imaging: TMRI | Read articles with impact on a number of artifacts and effects related to the physics at higher field strength.
Then, we tune the RF pulse to the precessing frequency of the hydrogen protons in the head.

Are there risks? The electrical current is transformed, via a computer, using a mathematical calculation called a Fourier transformation.

Abstract Our ability to interpret and process information and regulate emotion is determined by the structure and chemical makeup of our brains. MRIs employ powerful magnets which produce a strong magnetic field that forces protons in the body to align with that field.

|MRI uses magnetic fields and radio waves to measures how much water is in different tissues of the body, maps the location of the water and then uses this information to generate a detailed image.
So how do we get an image from these spinning, flipped hydrogen protons in the brain? The strength of the magnet is measured in a unit called Tesla T.
However, this randomness changes when we place a human body into a very strong magnetic field, like an MRI scanner. Because protons in the different kinds of tissues in the brain, such as gray matter, white matter and blood, all give off different amounts of energy, the result of the transformed energy is a highly detailed image of the tissue inside the brain. Although MRI does not emit the ionizing radiation that is found in x-ray and CT imaging, it does employ a strong magnetic field.

The stronger the magnetic field, the faster they spin.
Our minds constantly control the flow of information—our memories, thoughts, emotion, and imagination. What is MRI used for? To do this we use MRI. As the protons flip back and realign with B0, they give off energy.
