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). An MRI is a large imaging device that sits in its own room. It uses a harmless magnetic field and radio waves to get clear, sharp pictures of the inside of your brain.An MRI is used to detect bleeding in the brain, tumours or stroke. It is also an excellent device for detecting smaller strokes or strokes in the back of the brain, which other imaging devices can miss.MRI images show even more detail than CT scans, and can be viewed in 3-D on a computer screen.agnetic Resonance Imaging (MRI).
