*All
metallic objects on the body are removed prior
to obtaining an MRI scan.
*Patients
will be given a sedative medication to
decrease anxiety and relax the patient during the
MRI scan.
* MRI
scanning requires that the patient lie still for
best accuracy.
*Patients
lie within a closed environment inside the
magnetic machine.
6. *Relaxation
is important during the procedure and
patients are asked to breathe normally.
*Interaction
with the MRI technologist is maintained
throughout the test.
*There
are loud, repetitive clicking noises which occur
during the test as the scanning proceeds.
*patients
require injections of liquid intravenously to
*
enhance the images which are obtained.
*The MRI scanning time depends on the exact area of the
body studied, but ranges from half an hour to an hour
and a half.
