A CT or CAT (computed tomography) scan combines X-ray and computer technology
to show highly detailed, 3-D images of any part of the body, including
bones, muscles, fat, organs and blood vessels. Scans can also be performed
using a contrast solution (either swallowed or injected) to make tissues
and vessels more visible.
Leading-edge CT technology
The GE Healthcare 64-slice LightSpeed™ VCT scanner is the most advanced
CT technology available — it can capture images of a beating heart
in five heartbeats, an organ in one second, and perform a whole body scan
in 10 seconds. This technology results in less radiation exposure for
patients, and can be used to examine a wider range of conditions —
everything from exams of the heart, spine, lungs and colon, to advanced
techniques such as angiography, virtual colonoscopy and radiation therapy planning.
Dallas Regional Medical Center offers innovative diagnostic procedures
using the 64-slice LightSpeed VCT, including:
5-Beat Cardiac™ – Doctors can capture images of the heart and coronary arteries
in just five heartbeats. The quicker exam time and shorter breath hold
offers a more comfortable experience for sick or elderly patients.
Triple RuleOut™ – Three primary causes of mortality in patients with chest
pain are aortic dissection, pulmonary embolism and coronary artery disease.
Dallas Regional Medical Center doctors can use this single, quick scan
to help diagnose chest pain.
Stroke WorkUp – When treatment is delivered within the first hour after a stroke,
it can provide the best possible outcome for the patient. The LightSpeed
VCT provides the necessary speed and resolution required for rapid imaging
of blood vessels in the brain, so doctors can begin treatment as quickly
