CT
stands for computed tomography.
With
CT, doctors can view the brain, sinuses, spinal column,
bones, and internal organs.
Helical
CT offers several advantages over conventional CT, due
to its ability to scan rapidly. The results are decreased
radiation exposure, lower volume of contrast material,
and less time for the procedure.
CT
scans are generally performed to help diagnose the condition
of organs, like the brain, liver, or kidneys, and bony
structures, like the spine, pelvis, and hip. Other applications
include three-dimensional CT before and/or after surgery,
and vascular studies, known as CT angiography.
Sometimes,
contrast liquids are required to increase the visibility
of certain organs. Depending on the exam, you may be given
a contrast liquid by mouth and/or injection. For these
exams, you will be asked to avoid normal eating or drinking
for several hours prior to the exam. Because X rays are
involved, it is important to inform the technologist if
you are pregnant, or think you may be pregnant. The technologist
remains in voice contact throughout the procedure, which
takes about 10 to 20 minutes. In order to perform this
examination satisfactorily, we ask that you follow the
preparation instructions on the opposing panel. |
