What is MRI?
MRI is Magnetic Resonance Imaging that uses powerful magnetic fields and radiofrequency pulses to produce detailed pictures of organs and other internal body structures.
Unlike X-rays and Computed Tomography (CT) scans, MRI is a safe non-invasive imaging method that does not involve X-ray radiation.
The patient lies on a bed support that is moved through the
cylindrical magnetic tunnel where the scanning takes place. The magnetic field
temporarily aligns all the water molecules in the body and when radio waves are
directed to the areas of study, these aligned water molecules will change
position thus producing signals: a computer system then processes these
signals, and creates cross-sectional images.
An MRI scan process is painless. The patient is however required to
remain still for the duration of the scan process which can last between 30 –
45 minutes. Should there be a need for the patient to have a contrast material administered,
it is usually done using the intravenous method.
During the scan, patients will experience some knocking and loud
sounds. This is completely normal as it is how the machine operates. Patients
are given earplugs or headphones with music on. The scanner is well-lit and is equipped
with a two-way intercom system to constantly monitor and communicate with the
patient. You will at all times have voice contact with the radiographer, who
will observe you clearly from the control room through a closed circuit TV.
Metal and electronic objects that interfere with the magnetic field
are strictly prohibited. Prior to the scanning, patients will be screened using
a Patient MRI Safety Checklist.
