Fluoroscopy
is an imaging technique commonly used to obtain
real-time images of the internal structures of a
patient through the use of a fluoroscope.
For this imaging method , a patient
is placed between an
x-ray
source and a fluorescent screen; an
x-ray image
intensifier is employed to minimize
radiation exposure and a
CCD
camera allows the images to be played and
recorded on a monitor. The result is much like an
x-ray "movie”; the x-ray beam is continually passed
through the body part being examined, and is
transmitted to the monitor so that the body part and
its motion can be seen in detail. |

In general, fluoroscopy has a broad
application in radiologic procedures. It is often
used in studies of the gastrointestinal tract,
including those involving the use of barium,
arthrograms, orthopedic surgery, urological exams
and surgery, and angiography of the leg, heart and
cerebral vessels. It can also aid in the placement
of cardiac rhythm management devices such as
pacemakers
and
implantable
cardioverter defibrillators.
A wide variety of catheter placement
procedures also involve the use of a fluoroscope.
Some preparation may be involved for your exam; you
will be given specific instructions at the time of
scheduling. |
