WebNormally, the hydrogen protons in our bodies are randomly arranged. When a person’s body is placed in an MRI scanner, however, the protons align along the direction of the scanner’s strong magnetic field. Then, radiofrequency waves are turned on, making some of the protons change direction. After the radiofrequency waves are switched off ... WebGadolinium) may be given to a patient intravenously before or during the MRI to increase the speed at which protons realign with the magnetic field. The faster the protons realign, the brighter the image. MRI of a knee. What is MRI used for? MRI scanners are particularly well suited to image the non-bony parts or soft tissues of the body.
