What is X-Ray?
X-ray
or radiography, is the oldest and most
frequently used form of medical imaging.
Discovered more than a century ago, x-rays can
produce images of the structures inside the
human body. X-ray images are produced when a
small amount of radiation passes through the
body to create an exposure similar to
photography. These images can be captured on
film and/or digitally viewed from a computer
screen. X-ray is a fast and easy imaging method
used by physicians to obtain an “inside look”.
The discovery of x-ray has been called one of
the most significant advances in all of medical
history.
Common uses for X-Ray
One
of the most common uses of radiographs is to
assist physicians in identifying and treating
bone fractures. X-ray images of the skull,
spine, joints and extremities are performed
daily in hospital emergency rooms, sports
medicine centers, orthopedic clinics and
physician offices worldwide. The images can even
show very fine “hairline” fractures or bone
chips. X-rays are often produced after treatment
to ensure that a fracture is properly aligned
and is healing appropriately. Bone x-rays are
essential tools in orthopedic surgery such as
joint replacements, fracture reductions or
spinal repair.
X-rays can be used to diagnose and monitor the
progression of degenerative diseases such as
arthritis. They can also play an important role
in the detection and diagnosis of cancer,
although usually computed tomography (CT) or
magnetic resonance imaging ( MRI ) is better at
defining the extent and the nature of a
suspected cancer. At least two and sometimes
three to four images are obtained from different
angles in order to properly view the anatomy.
Another common type of x-ray taken is of the
chest. Chest x-rays are a simple way of
providing physicians with valuable information
concerning the general condition of your health.
They are used primarily to evaluate the lungs,
heart, large arteries, ribs, and the diaphragm.
Chest x-rays are frequently utilized in cases of
suspected pneumonia, tuberculosis, lung tumor or
collapsed lung.
How does it work?

An x-ray examination involves exposing a part
of the body to a small dose of radiation to
produce an image of the internal structures.
When x-rays penetrate the body, they are
absorbed by the varying amounts densities within
tissues. Ribs, for example, are dense and will
block much of the radiation and, therefore,
appear white or light gray on the image. Soft
tissue such as the liver or lungs will appear
darker because more radiation can pass through
them to expose the film. The images may be
transferred to film or may be stored
electronically on PACS (picture archiving and
communication system). After a few months or
even years, these images may be used to compare
with more recent radiographs if needed.

Patient Comfort
The test itself is completely painless. Some
mild discomfort may result from lying on the
table, a hard surface that may feel cool.
Sometimes, to get a clear image of the injury,
you may be asked to hold an uncomfortable
position for a moment while the x-ray is taken.
Any movement could blur the image and make it
necessary to repeat the procedure to obtain a
useful, clear picture.
Preparation
Although there is no special preparation
required for most x-rays, you may be asked to
change into a comfortable robe before your exam.
Metal objects can affect the image, so on the
day of your exam, avoid clothing with zippers
and snaps if possible. You may be asked to
remove hairpins, jewelry, eyeglasses and hearing
aids depending on which body part is being
examined. Women should always inform their
doctor and/or technologist if there is any
possibility that they may be pregnant.
After the test
Patients are able to return to normal
activities immediately following the exam.
