The utility of computed tomography (CT) in clinical practice continues to grow, related in
large part to advancements in technology. In 1997, more than 27 million
CT scaning procedures were performed in the United States, with the
number of studies increasing at a rate of 10% per year.1
With the introduction of helical technology (eg, a continuous spiral
motion of the gantry—the frame that houses the rotating x-ray tube),
the list of accepted indications for CT imaging has substantially
increased, particularly in the evaluation of acute thoracic and
abdominal conditions. Helical technology is relatively easy to perform
and is widely available in primary and tertiary care settings. We
report selected advances in CT imaging that are proving clinically
useful in a general medical practice.
