What is an MRI?
MRI is a safe and revolutionary technology which can be used to study any part of the human body and gather detailed information about it. During an MRI examination, the patient is placed in a strong magnetic field, and radiowaves are then used to gather information about the part of the body being studied. This information is then processed by a computer and images of the body are obtained.
Who should not have an MRI examination?
Patients who have certain types of metallic objects near vital organs (particularly in the brain or in the eyes), TENS electrical stimulators, cardiac pacemakers, or cochlear implants should not have an MRI examination. Also, any patient who has had an adverse reaction to intravenous contrast (or "dye" injected into the veins) should notify the technologist prior to the examination. Prior to the examination, our MRI technologists will ask more detailed questions of MRI patients to ensure that no contra-indications to MRI exist.
Are MRI examinations safe?
For patients who do not have contraindications to an MRI examination, MRI is one of the safest ways to obtain detailed information about the body, and does not use harmful radiation.
What else should I know about an MRI examination?
Patients who are extremely claustrophobic may need to be lightly sedated during the MRI examination, since the examination takes place in a tubular compartment which houses the MRI equipment. Intermittent loud knocking noises will also be heard during the examination. Sometimes it is necessary to inject a medication called contrast into the veins or into joint spaces during the examination to aid in the diagnosis. It is very important not to move during the examination. The technologist will be able to hear you during the examination, which usually lasts between 30-90 minutes.
