But the ultimate meaning of this song to me, and I hope to others, is that even though I'm giving up on this person, on us. I wish with every fiber of my body that you would say something. Anything to give me hope again.Even though I know I'm tired of it all, my heart still wants wants them.ou're to the point where you are begging them to say something, to give them a sign that they are still here, and with you... even though you know they aren't. Another way, could be about love. You are trying harder than you should in a relationship, and you aren't sure if you even want this.
An MRI scanner applies a very strong magnetic field (about 0.2 to 3 teslas, or roughly a thousand times the strength of a typical fridge magnet), which aligns the proton spins.. The scanner also produces a radio frequency current that creates a varying magnetic field.
What is an MRI scan? An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves.
