What
is High
Definition Magnetic Resonance Imaging?
High definition Magnetic Resonance
Imaging, or MRI, is the latest gener ation
of MRI scanners that create images of the body using a magnetic field
and radio waves. As a versatile, powerful and sensitive tool, MRI can
generate thin section images of any part of the body from any angle in a
relatively short period of time. With the addition of high definition,
we are now able to provide images at a higher resolution than ever seen
before, decrease patient motion artifact and shorten scan times in a
much more comfortable and relaxed environment.
In addition to MRI offering images
of the internal soft structures of the body, it also visualizes both the
venous and arterial vessels within the body. This is known as MRA
(Magnetic Resonance Angiography). This feature allows physicians to
gain the same multi-dimensional imaging of blood vessels as offered with
conventional MRI, supplementing and often replacing conventional
catheter angiography.

What
are the Preparations for the Exam?
If you have a PACEMAKER, SURGICAL
CLIPS, PROSTHESIS, METAL IMPLANTS or any other object in your body, you
should notify the nurse or technologist before entering the magnet area.
The staff will determine if the exam can safely be completed. All other
metallic objects should be removed before entering the magnet room. If
you are claustrophobic you should inform your physician and our staff
prior to your appointment. Our caring personnel will assist you in
successfully completing the exam. Your pre-exam preparation will depend
upon the type of exam your physician has requested.
Some studies may require fasting
prior to the exam if it requires the use of contrast material for
further enhancement of the area being imaged. Other studies do not
require any further preparation beyond removing all jewelry or body
piercing prior to your arrival at DRA Imaging. Please check with either
your physician or our office in regards to any special instructions or
questions you may have related to your exam.
