X ray equipment is 3-phase with a moving table. All
types of bones studies, chest and abdominal X rays, head
and neck, and spine exams can be performed.
What is a routine X ray?
The X ray has been called one of the most significant
advances in all of medical history. It is used in many
different ways in medical diagnosis. An X ray image is
produced when a small amount of radiation passes through
the body and strikes a sheet of sensitive film placed on
the other side of the body. The ability of X rays to
penetrate tissues and bones varies according to the
tissue's composition and mass. Bone, which contains
calcium, does not let much radiation through and results
in white images on the X ray film. The lungs, which are
filled with air, allow nearly all X rays to strike the
film resulting in a black image.
Common uses of this procedure
Probably the most common use of bone radiographs is to
assist the physician in identifying and treating
fractures. X ray images of the skull, spine, joints, and
extremities are performed every minute of every day in
hospital emergency rooms, sports medicine centers,
orthopedic clinics, and physician offices. Images of the
injury can show even very fine hairline fractures or
chips, while images produced after treatment ensure that
a fracture has been properly aligned and stabilized for
healing. Bone X rays are an essential tool in orthopedic
surgery, such as spinal repair, joint replacements, or
fracture reductions.
X ray images can be used to diagnose and monitor the
progression of degenerative diseases such as arthritis.
They also play an important role in the detection and
diagnosis of cancer, although usually computed
tomography (CT) or MRI is better at defining the extent
and the nature of a suspected cancer. On regular X rays
severe osteoporosis is visible, but bone density testing
can show even early bone loss.
How does it work?
Routine X rays involve exposing a part of the body to a
small dose of radiation to produce an image of the
internal organs. When X rays penetrate the body, they
are absorbed in varying amounts by different parts of
the anatomy. Ribs, for example, will absorb much of the
radiation and, therefore, appear white or light gray on
the image. Lung tissue absorbs little radiation and
appears dark on the image. Usually, all chest organs
will appear normal, and the radiographs will be filed
away. The exposed film is either placed in a developing
machine, producing images much like the negatives from a
35-mm camera, or digitally stored on a computer. After a
few months or years, the images may be used to compare
with later radiographic views of the chest if illness
develops.
Benefits of a Routine X ray
X ray imaging is useful to diagnose bone injury and
disease, such as fractures, bone infections, arthritis,
and tumors. They can diagnose pneumonia, emphysema, and
sometimes sinus infections.
Because X ray imaging is so fast and easy, it is
particularly useful in emergency diagnosis and
treatment.
