MRI TechnologyUnpaired nuclei in an atom have a resultant spin. We apply a strong magnetic field, so that they align themselves (in their own ways!). Then we blast them with a radio frequency pulse to make them feel dizzy. However, the nuclei (proton) though perturbed, they revert back to their 'original' configuration; releasing an RF pulse that is detected. This 'pulse' is interpreted and visualized by the radiologists.

The above is an oversimplification, since in addition to this, we need to know how the nuclei 'relax': T1 & T2 relaxation.

You may learn more about this (in layman's as well as professional terms) in my blog article: Understanding the Basic Principles of Nuclear Magnetic Resonance Imaging. Please see the related link.

There's much more to it (e.g. relaxation) which I've also covered.

The abbreviation is MRI and it means: a special radiological test that uses magnetic waves to create pictures of an area, including bones, muscles, and tendons. MRI is often used in medical clinics.

MRI is a form of Nuclear magnetic resonance (NMR) which uses a magnet to interact with hydrogen nuclei for instance. As the body is made up of 70% water, and water is 2 parts hydrogen, there is a lot of hydrogen in your body. Damage to tissues can therefore be seen rapidly.

The purpose of magnetic resonance imaging also known as MRI is to obtain pictures of inside a body and figure out what problem may be occurring. A MRI can provide different results than an X-ray or ultrasound.

It's a magnetic resonance imaging: the use of nuclear magnetic resonance of protons to produce proton density images (Basicly a high tech X-ray using elements) What exactly does it mean?

Does a person need a GFR blood test done before having a MRI?

Not always. Before a routine MRI scan no GFR test is needed. Some MRI scans will require an injection of a drug (contrast) which is used to highlight different aspects of blood supply. There is a small risk of this contrast affecting kidney function so some MRI centres test kidney function before administration. One such test is GFR
