CT Built for Speed
In July a new
General Electric high speed CT (computed tomography) unit was installed
in the Veterinary Teaching Hospital. According to Dr. Matt Bischoff,
a fellow in diagnostic imaging, The new CT is a significant improvement
over our previous unit.
acquired with the new CT unit can be used to create three-dimensional
reconstructions for research, teaching, and clinical applications.
The CT is mainly
used as a diagnostic tool. For example, its cross-sectional view of
the body helps find suspected tumors in nasal cavities, the thorax,
and the abdomen. It is also often used to examine spinal cord lesions
after myelography and to evaluate certain orthopedic diseases, such
as osteochondrosis in dogs legs.
new unit acquires one slice (image) per second. This is considerably
faster than the previous CT unit, which could acquire only five to six
slices per minute. On average, most studies consist of 80 to 100 images.
With the increased speed of the new unit, patients are under anesthesia
for a shorter time period. Eventually, certain procedures may be able
to be performed under sedation rather than general anesthesia, notes
imaging technologist Richard Keen.
In addition to decreased image acquisition time, the new unit is able
to reconstruct additional images in multiple planes (sagittal, dorsal,
or oblique) within seconds. Images acquired with the new CT unit can
also be used to create three-dimensional reconstructions for potential
research, teaching, and clinical applications (such as with comminuted
fractures). The new unit is also more compatible with the PACS system
for image archiving, and the images are accessible through the hospitals
With its speed and advanced capabilities, the whole imaging process
is now more efficient for patients and clinicians alike.
