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.
Magnetic resonance imaging (MRI) is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these aligned atoms to produce very faint signals, which are used to create cross-sectional MRI images â like slices in a loaf of bread.
