X-rays are a form of ionizing radiation that was first discovered
by William Conrad Roentgen in 1895. A beam of X-rays can
be produced by bombarding a tungsten target with a stream
of electrons, inside an X-ray tube. The X-ray beam can penetrate
through the body, exposing a sheet of photographic film
which records the image cast upon the film by the differing
absorption of portions of the beam, by tissues of varying
density within the body. For example, the lungs are easily
seen because they contain air, allow most of the X-ray beam
to pass through, and appear dark on the film. Bones are
clearly seen for the opposite reason: they absorb most of
the X-ray beam that strikes them, and appear white on X-ray
films.
Exposure to any radiation is potentially hazardous, although
the amount used for diagnostic examinations is extremely
small – similar to the amount of radiation we receive
each month or year from natural sources. Diagnostic X-rays
are requested by your physician and performed by us, only
when the potential benefit to you far outweighs any potential
harm.
X-ray films are very useful for examining the lungs and bones (including the spine) and can also be used for evaluation of the skull, sinuses and abdomen, and all other bones in the body.
Because X-rays are a form of ionizing radiation, women will
be asked for a menstrual history, to determine if there
is any possibility of pregnancy. For X-rays of the chest
or abdomen you will be asked to put on a gown that has no
metal snaps or zippers. The examination may be performed
while you are standing (chest X-ray), sitting (hand), or
lying on an examination table (abdomen).
In most cases, reports are provided within two business
days.
