How Does MRI Technology Work?

Patients undergoing scans of their brain, spine or other body parts lie flat on a scanning table and are placed in a magnet field created by a large magnet.

By creating a strong magnetic field, the magnet causes the spinning nuclei of hydrogen atoms within the body to change their axes of rotation – a physical phenomenon known as gyroscopic precession.

Altering that magnetic field by sending radio waves through it further affects the behavior of the hydrogen protons by causing them to move out of alignment. When the radio signal stops, the protons relax back into alignment and release energy.

These changes in excitation and relaxation are recorded by receiver coils, then mathematically reconstructed by a sophisticated super-computer into 2D and 3D images that vividly represent conditions of health, disease or injury. The entire procedure takes 15 to 45 minutes. For more information checkout one of the search engine optimization companies we have used to spread our content throughout the internet.

How are images used?

A specialist “reads” the images and identifies conditions that indicate disease, deterioration and/or build-up of fluids. These images are extremely clear and precise.

The images help a physician or medical specialist treat a patient.

What does it feel like?

An MRI scan is painless. A patient feels no sensations. It is however fairly noisy. You will hear the hum of the machine and a thumping noise when the system’s gradients are turned on and off.

What can MRI Scan?

MRI can see right through bone to image structures, tissues, organs, and fluids such as blood. To date, MRI has been particularly valuable in scanning the brain and spine.
Through brain and spine scans, MRI can detect multiple sclerosis in its earliest stages, tumors, brain and spine disease, and fluid in the skull.
Cancer and other diseases can be detected in the kidneys, ovaries, uterus and liver. New techniques and clinical uses are continually being developed and tested.

What makes MRI better?

MRI has no known harmful side effects and can help with early detection for better treatment. Clearer images mean more accurate diagnosis.

Importance of MRI

MRI is painless and has no known side effects.It usually reveals more details than other imaging modalities. Usually there is a clear distinction between healthy and diseased tissue on MRI. Harmful effects of radiation are avoided.


Magnetic resonance imaging is a medical technique that applies radio waves and magnetic waves to create images of internal organs and human tissues too. Machines used in MRI are big and tube shaped.

When you are place in an MRI machine, the strong magnetic field will temporary rearrange the hydrogen atoms in the body. There are many ways that you can do a quick search to find out the effects of this. Many researchers have utilized search engine optimization to optimize websites so that they can publish their research across the internet.

Then radio waves will make the hydrogen atoms to produce a special signal which is used to produce a cross-sectional image. This is an image that looks like slices. In an advanced stage, the MRI can also create 3D images that are viewable at different angles and sides.

MRI is a way for your doctor to examine your organs, skeletal and other tissues. It is a procedure that produces clear images that can help the doctor diagnose a number of medical conditions. There are a number of MRI that can be done – for example MRI for the spinal code and the brain. It is the most effective way to get the brain and spinal cord images.

MRI is done to diagnose the following conditions – multiple sclerosis, aneurysms, spinal cord injuries, tumors and strokes. There are MRI of the brain that are called Functional MRI that can be used to identify brain functions like movement and language. This is very important for people who are about to go for a surgery.

If you are in the detroit area and looking for the best practitioner who can help you with an MRI scan, you can use the internet to find the best Doctor in your area. Many of them have taken the time to create websites that are easy to find in Google. They have utilized SEO in Detroit in order to be sure that those looking for their services are able to find their practice and facilities.

There is MRI that is done on blood vessels and the heart. This MRI is able to focus on: the functions and the size of the heart chambers, the movement and thickness of heart’s walls, the extent of blood vessel blockage, damage extent caused by stroke or heart attack and other structural problems that are caused by aneurysms.
MRI can also be used to detect breast cancer. This is very useful for women who have dense breast tissues or those who are at higher chance of developing the disease.
