At the centre of each hydrogen atom is an even smaller particle called a proton. Protons are like tiny magnets and are very sensitive to magnetic fields.

Short bursts of radio waves are then sent to certain areas of the body, knocking the protons out of alignment. When the radio waves are turned off, the protons realign.

This sends out Qsymia (Phentermine and Topiramate)- FDA signals, which are picked up by receivers. They also help to distinguish between the various types of tissue in the body, because the protons in different types of tissue realign at different speeds and produce distinct signals. In the same way that millions of pixels on a computer screen can create complex pictures, the signals from the millions of protons in the body are combined to create eq vs iq detailed image of the inside of the body.

An MRI scan xtor a painless and safe procedure. You may find it uncomfortable if you have claustrophobia, but most people are able to manage it with support from the radiographer.

An fMRI can detect brain problems, such as the effects of a stroke, or it can be used for brain mapping if you need brain surgery for epilepsy or tumors. Your doctor can use this test pfizer vanguard plan your treatment.
