X-ray
X-rays, also known as "radiographs" or
"plain films" are the oldest and most frequently
used form of medical imaging. Because tests
are not always conclusive, sometimes physicians
will suggest another imaging test in addition to
plain X-rays.
What is fluoroscopy?
Fluoroscopy is a form of X-ray imaging
that enables the radiologist to visualize real
time movie-like images of an organ or area
of concern. It is commonly used to evaluate
the gastrointestinal system, but also used in
procedures such as arthrography,
hysterosalpingograms and
lumbar punctures.
What is X-ray dye?
X-ray dye, also known as contrast dye or medium,
is a solution that is used to accentuate specific
structures when looking at an image.
In X-ray and CT studies, the contrast dye is
any internally administered substance that
has a different density from soft tissue. Having
a different density than soft tissues means the
X-ray interacts in such a way that provides
"contrast" between adjacent structures.
This allows the radiologist to see anatomy
more clearly.
