What does resonance in MRI mean?

Magnetic resonance occurs when external energy is injected into a nuclear spin system near the Larmor (resonance) frequency. In both NMR and MRI, the primary source of energy input is from a rotating magnetic field (called B1) generated by passing alternating current through a nearby radiofrequency (RF) coil.

What is resonance in radiology?

Magnetic resonance imaging (MRI) of the body uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the inside of your body. It may be used to help diagnose or monitor treatment for a variety of conditions within the chest, abdomen, and pelvis.

What type of resonance is utilized in MRI?

MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy.

At what frequency does resonance occurs in MRI?

With the strong magnetic fields generated by the superconducting magnets used in modern NMR instruments, the resonance frequency for protons falls within the radio-wave range, anywhere from 100 MHz to 800 MHz depending on the strength of the magnet.

How is NMR applicable in MRI?

MRI uses the same physical effect as Nuclear Magnetic Resonance (NMR) spectroscopy, in which the identity of an unknown compound (like a potential new drug) may be identified by the resonant properties (the jiggling of protons) of the atoms that comprise it.

What is resonance frequency?

Resonant frequency is the oscillation of a system at its natural or unforced resonance. Resonance occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.
