Computed Tomography (CT) is a sophisticated imaging technique that can demonstrate anatomy at different angles around the body. With computer aid, these techniques provide clear, sharp, detailed cross-section imaging of the anatomy.
To perform this type of imaging, special equipment is needed. Using multi-detector technology, the technologist can produce thinner slices at a faster speed. This allows more versatility in the type of anatomy that can be covered, reduces the amount of time it takes to perform the procedure and reduces the amount of radiation exposure.
With the continuous rise in technology, CT, along with other areas of medicine, is making immense strides in patient care. Three-dimensional imaging is just one of the sophisticated imaging techniques performed in CT. This technique produces life-like images of the body. Radiologists are able to visualize patient anatomy more realistically. 3D imaging may be performed during a variety of exams. For example, 3D can be used to visualize internal abdominal organs, lungs, extremities, skull, facial bones and the heart. 3D is often used to evaluate fracture sites and stent placements within the human body.
Another imaging technique used at Uniontown Hospital is CTA (Computed Tomography Angiography). It allows for 3D and High Intensity imaging of major arteries and veins throughout the body. Why perform a CTA? This non-invasive technique is often used for the detection of aneurysms, pulmonary emboli and other vascular structures within the body.
What Should I Expect During a CT Exam?
- The technologist or radiologist will ask for a medical history.
- Depending upon doctor's orders, and at the radiologist's discretion, you may receive oral or IV contrast.
- You will be asked to lie down on a padded table.
- The type of CT scan ordered determines the amount of time spent in radiology.
- The examination is checked and read by a radiologist.
