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.
Most MRI machines are powerful, tube shaped magnets large enough to surround your body. The MRI aligns the water molecules in your body and hit it with radio waves, which return signals that the computer turns into images.
