A
computer screen in the radiology department displays a dozen x-rays,
both from the patient’s medical records, and from today’s visit. With
the click of a mouse, Dr. Jeff Peterson selects the most recent one,
taken just moments ago, to be enlarged on a neighboring screen. Another
click and he zooms in on a suspicious looking area which has been
enhanced to show greater detail. Concerned by what he sees, Dr. Peterson
sends the image by secure e-mail to a consulting radiologist at another
facility. By the time he returns to the clinic, a phone call comes into
his office. Dr. Peterson pulls up the image on the computer at his desk
and discusses it with his colleague many miles away. A diagnosis is made
and the appropriate course of treatment can be taken.
Cases like this one (fictionalized
for the sake of patient privacy) are possible thanks to the latest
technology to come to Bridges Medical Center in Ada. The Computer
Radiography (CR) and Picture Archiving and Communications System (PACS)
replaces traditional x-ray film with digital imaging grids. Images are
captured and immediately downloaded to a computer system for review.
Instead of waiting for the film to be unloaded and processed in the
darkroom, the technician can review the image instantly, much in the way
that pictures can be reviewed on the LCD screen of a digital camera.
Additional x-rays, if needed, can be taken in rapid succession, greatly
reducing a patient’s time in the radiology department.
The wall-size banks of light boxes
have been replaced with computer screens so that a physician can review
them from within the radiology department, the emergency room, or in the
clinic, or anywhere there is access to Bridges computer system. Images
and patient information can even be sent to specialists and consulting
professionals in other facilities via secure transmissions.
Another advantage is the ease with
which images can be archived and retrieved. For decades, x-rays and
other radiographic images have been stored in large file folders in
rooms filled with shelving units on rollers. Retrieving an x-ray for
comparison or review meant that someone had to physically go to the
storage room, find the patient’s folder, and pick through it by hand to
find the desired image. If a consultation with someone outside of the
facility was desired. The image was copied in the darkroom and sent by
courier to the desired destination. The process could take more than an
hour if the situation was critical, or days for routine review. Films
were also at risk of loss or damage by fire, water, or even to time
itself. Now images can be backed-up to on-site or off-site data banks to
be retrieved anytime from anywhere (after meeting the security
requirements for accessing patient data). Patient files, which consisted
of one or more folders of heavy x-ray films, can now be burned onto a
single CD or DVD weighing less than an ounce.
The expense of creating and storing
images has also been reduced by the elimination of expensive x-ray film
and processing chemicals, the cost of courier services, and the
reduction in space lost to storage. Over time, this will help offset the
cost of the $95,000 system, which was purchased with the assistance of a
$35,000 grant from the Minnesota Department of Health.
The CR/PACS system replaces the
film based imaging from x-rays, MRI’s, and CTscans, and will replace the
film used in Ultrasound exams sometime in March of this year.
“Bridges has taken another step to
narrow the technology gap between rural and urban medicine,” said
Bridges Medical Director, Dr. Jeff Peterson, M.D. “One of our goals is
to help people from this region access cutting edge technology and
services without having to leave their home community.” |
