Bone Density NY
One of the best ways for physicians to detect and treat early signs of bone
deficiency – like osteoporosis – is to test for bone density via
diagnostic imaging.
A bone densitometry scan is a special type of X-ray test used to measure the
calcium content of the bone, usually in the lumbar region (the lower back) and
the hips. The examination is also called a DEXA-scan, QDR-scan or BMD (bone
mineral density) measurement.
A bone densitometry scan measures the calcium content in the bones, which cannot
be measured in an ordinary X-ray. Although an X-ray may appear to show that
the bones have low calcium content, the information is vague for evaluating
any potential ailments, so someone with osteoporosis may have perfectly normal
X-rays. An X-ray is far more reliable when it comes to detecting a recent bone
fracture.
East River Imaging is equipped with the GE Prodigy Bone Densitometer, a world
renowned dual photon x-ray system that allows for maximum detail when evaluating
properties of the hip and spine. Radiologists at the leading multi-modal facility
East River are dedicated individuals who have been praised by colleagues for
their insight and experience in diagnostic medicine and bone densitometry. Equipment
like the Prodigy Bone Densitometer used at the East River clinic NY requires
only minute levels of radiation to assess the strength and density of the bones
in your body. It will also compare your measurements to a reference population
based on your age, weight, sex and ethnic background. This information will
enable your physician to determine whether you are at risk for fractures due
to osteoporosis.
Fortunately, a variety of supplements are available to help treat poor levels
of bone density. A scan can help a doctor who is examining a patient for osteoporosis
to assess their risk of having a bone fracture within the next few years. In
general, people with a bone mineral density significantly lower than that normal
for their age and sex are more likely to break a bone. If the patient then receives
medical treatment, the scan can be repeated after two years to assess their
progress.
The PETCT scan will take between 10 and 30 minutes, depending on the equipment
used and the parts of the body examined. If the doctor is checking for osteoporosis,
the lumbar spine and the hips are usually examined, as well as the forearm as
it will give a different calcium content from other body parts. Patients can
eat immediately before the test and remain fully dressed as long as their clothes
have no metal buttons or zippers. Recently portable scanners, which can be used
in a GP's surgery and check the BMD of the heel bone have been growing in popularity.
New methods of measuring osteoporosis using ultrasonography have also been
developed. One such ultrasound system measures BMD at the patient's heel and
takes about a minute. The ultrasonography for testing osteoporosis are smaller
and less expensive than traditional DEXA systems. These systems have recently
received US Food and Drug Administration (FDA) clearance. The hope is that this
more compact, lower cost system will allow this vital diagnostic test to become
more widely available in the future. By primarily measuring peripheral sites
such as the heel, ultrasound densitometry may not be as sensitive as techniques
such as DEXA or QCT that measure the spine or hip since the heel may be normal
in bone density even when central sites such as the hip or spine are already
significantly abnormal.
Further, bone density/densitometry changes in the heel occur much slower than
in the hip or spine. Therefore ultrasound densitometry should not be used to
monitor a patient's response to therapy. However, the new ultrasound densitometry
systems will allow many more people access to bone densitometry and potentially
diagnose osteoporosis before a traumatic fracture occurs.
