Computed tomography // Introduction
Computed tomography is an x-ray exploration that produces detailed images of axial cuts from the body. Instead of getting an image as the x-rays, a CT scan gets multiple images by rotate around the body. A computer combines all these images into a final image that represents a cut of the body as if it were a slice. This machine creates multiple images around region of the body to study.
What are the key advantages of this study?
The ability to produce images of cross sections with varying thicknesses, less than a millimeter of thickness without overlap of elements above or below. It provides very high resolution anatomical details, obtaining data of diseases before that by other methods.
- 1. The use of contrasts by computerized injectors pumps, synchronized with the scanner enables excellent far exceeding conventional contrasted studies.
- 2. Reconstructions in two and three dimensions in color, or black and white, with excellent information and anatomical detail.
- 3. Angiography CT: CT multislice can do vascular studies of any territory with high image quality giving real angiographies CT.
