Sounds heard during the imaging come from the pulsing of the magnetic field as it scans the body. MRI uses a large circular magnet and radio waves to generate signals from atoms in the body. Imaging of tissues within the body after they are bound by fluorescent molecules and stimulated with light in the 700-900 nm wavelength range.
Often they can be given medication prior to the MRI to help make the procedure more comfortable. MRI makes use of radiofrequency pulses and a strong magnetic field to give detailed pictures of the targeted organs on a computer screen. MRI scanning is a non-invasive and painless procedure. A magnetic resonance imaging scan (MRI) produces an image of the body using a strong magnet and radio waves. What is the difference between a cyst and a tumor? fMRI is also used in clinical practice.
