An MRI scan requires three basic components including a computer, magnetic field, and radio waves. The three elements are used to create visually advanced and clear images of the internal organs of a human body. The human body has numerous hydrogen atoms, which are magnetic in nature. When the body is out into a magnetic field, these atoms align with the field’s intensity. With the radio wave, the MRI machine works against the polarity of these atoms and the time these atoms take to resume to their magnetic condition is measured using a sensor.
MRI procedure is used to check the water/ fluid content of the body and the images show it as black-colored accumulation in the images.
To further advance the imaging, the doctors may use a dye to your bloodstream and check specific tissues. The gadolinium content of the die has magnetic properties, which when absorbed by any organ, stands out in the images.
