MRI
Scanning....
We
are able to offer a speedy solution to the
sometimes long NHS waiting lists for MRI
scans. Our Physiotherapists are trained to
assess and conclude that an MRI scan will be
beneficial to the speedy recovery of a
patient.
Why Wait?
We have the system in place to refer
patients privately (following physiotherapy
assessment) for MRI scans at various
hospitals in the North East. Waiting is
usually reduced to 7days and results are
returned to us 48hours after the scan.
What is an MRI scan?
MRI (magnetic
resonance imaging) is a fairly new technique
that has been used since the beginning of
the 1980s.
The MRI scan
uses magnetic and radio waves, meaning that
there is no exposure to X-rays or any other
damaging forms of radiation.
What does
an MRI scan show?
Using an MRI
scanner, it is possible to make pictures of
almost all the tissue in the body.
Physiotherapists often recommend MRI
scanning to ensure an accurate diagnosis of
problems such as prolapsed disc (sciatica)
or cartilage tears of the knee.
Having viewed the pictures, a radiologist
can then compile a report outlining the type
and severity of the injury and give a more
accurate diagnosis and prognosis (length of
time the injury will persist). This in-turn
will lead to a more successful treatment out
come.
How does an MRI scanner work?
The patient lies inside a large,
cylinder-shaped magnet. Radio waves 10,000
to 30,000 times stronger than the magnetic
field of the earth are then sent through the
body. This affects the body's atoms, forcing
the nuclei into a different position. As
they move back into place they send out
radio waves of their own. The scanner picks
up these signals and a computer turns them
into a picture. These pictures are based on
the location and strength of the incoming
signals.
What does an MRI scan show?
Using
an MRI scanner, it is possible to make
pictures of almost all the tissue in the
body. The tissue that has the least hydrogen
atoms (such as bones) turns out dark, while
the tissue that has many hydrogen atoms
(such as fatty tissue) looks much brighter.
By changing the timing of the radiowave
pulses it is possible to gain information
about the different types of tissues that
are present.
An MRI scan is also able to provide clear
pictures of parts of the body that are
surrounded by bone tissue, so the technique
is useful when examining the brain and
spinal cord.
Because the MRI scan gives very detailed
pictures it is the best technique when it
comes to finding tumours (benign or
malignant abnormal growths) in the brain. If
a tumour is present the scan can also be
used to find out if it has spread into
nearby brain tissue.
The technique also allows us to focus on
other details in the brain. For example, it
makes it possible to see the strands of
abnormal tissue that occur if someone has
multiple sclerosis and it is possible to see
changes occurring when there is bleeding in
the brain, or find out if the brain tissue
has suffered lack of oxygen after a stroke.
The MRI scan is also able to show both the
heart and the large blood vessels in the
surrounding tissue. This makes it possible
to detect heart defects that have been
building up since birth, as well as changes
in the thickness of the muscles around the
heart following a heart attack. The method
can also be used to examine the joints,
spine and sometimes the soft parts of your
body such as the liver, kidneys and spleen.
