X-ray
X-Rays: To See Is To Know
Dr. Cady may discuss taking x-rays of your spine before beginning
your program. Different bone structure in patients is important
to see before a specific adjustment is made. The doctor may then
choose different directions for the forces to ensure that the
adjustment results in the best correction of the problem. In 5-6%
of the population, the spinal structure has a fracture at a portion
of bone in the low back. This fracture (called a spondylolysis)
usually develops due to a genetic weakness in the area. It can
also be caused by trauma such as in gymnastics or football. The
fracture has been identified in a child as young as two years
of age. Back pain may or may not be present when this abnormality
exists. The separated bone can subluxate forward. This is called
a spondylolisthesis.
In addition to fracture, the x-ray is also used to see small changes in
alignment called subluxations. The doctor uses the
position of bones to determine where the ligaments in your spinal column have
been stretched or torn. A three-dimensional picture in the doctor's mind is
needed prior to the adjustment. The adjustive force
is then made in a precise fashion into the directions that reduce tension on the
damaged ligaments. Since a high speed thrust into your spinal column is a
vigorous procedure, it is important that the doctor use x-ray to more precisely
determine how the adjustment is to be made. Also, when the precise correction of
the subluxation is made from the start of care, fewer adjustments are usually
needed because of their more correct nature.
The usefulness of x-ray in assisting the doctor in both diagnosing
and adjusting the subluxation is apparent. The benefits of x-ray
however, must always be weighed against the risks of exposure
to radiation. For this reason, pregnant women are often excluded
from x-ray examination since the fetus is more sensitive to exposure.
In most cases, the benefits of the x-ray outweigh the small risks.
Dr. Cady tries to reduce exposure and protect you as much as technology
allows. Dr. Cady will discuss your individual health concerns
and information that was detected in your x-ray examination. When
patients understand their health problems and the objectives of
the chiropractor, they respond more quickly to care.
X-Ray Safety
Chiropractors Often Utilize X-Ray Studies: Based on the nature of your
condition as well as a number of other factors, x-ray studies of your spine or
injured body part may be indicated. Doctors of chiropractic receive over 300
hours of x-ray studies in college prior to graduating and thus are fully trained
to take radiographs and identify subtle abnormalities of the spine as well as
more serious pathologies.
X-Rays Are Safe and Provide Valuable Information: X-rays
are a relatively safe and cost effective way to view the structure
and general condition of the spine. They can reveal spinal regions
under high stress and expose areas of degenerative change. This
can often provide essential additional information which correlates
history and examination findings allowing for a more accurate
spinal analysis and a more individualized and effective treatment
plan. X-rays are also useful in assessing the appropriateness
of chiropractic care as they can help to rule out the existence
of more serious pathological processes such as spinal fractures,
tumors and infections which require immediate emergency medical
intervention.
Procedures Used To Minimize Exposure: While prolonged exposure to
radiation can be potentially harmful to the human body, the diagnostic x-rays
utilized by the chiropractic doctor pose a minimal health risk. In fact,
according to radiation guidelines for diagnostic x-ray studies, it would take
more than 300 full spine x-rays performed by a chiropractor for these guidelines
to be met. In addition, the following steps are used to further reduce the
amount of x-ray exposure:
-
Only necessary x-ray views will be
taken eliminating unnecessary x-ray exposure.
-
Shielding to block or reduce the
x-ray beam from affecting sensitive tissues and areas of non-diagnostic
interest
-
Rare earth (intensifying) screens
can cut x-ray exposure by 50 percent
-
Collimation to narrow the x-ray
beam to include areas of interest only
-
Grids to reduce scatter radiation
and improve x-ray quality
-
High speed film lowers exposure
time
-
Increasing kilo voltage and
minimizing mill amperage further reduces x-ray dosage
-
Minimal exposure times of just
100ths of a second
-
Regular changing of processor
chemicals to give high quality, diagnostic films
