At Emery Medical Solutions we specialize in CT Scan services in Apopka and all of Orlando. Computed Tomography, widely known as a CAT scan, is medically referred to as simply CT. In its early days of development and use, it was called Computerized Axial Tomography, hence the term CAT.
CT is generally a relatively quick procedure that uses x-ray beams to create computer-generated image of soft tissue structures, such as tumors and internal organs, and air cavities (sinuses, lungs). It also has advantages in skeletal and neurological imaging. Its radiation doses to the human body are considered minimal due to the speed in which the X-Ray is delivered.
The procedure requires you to lie in a horizontal position, either on your back or stomach, and remain comfortably still. A flat, moving table goes through the center of a donut-shaped x-ray machine. X-ray beams from a number of positions are aimed at the area being studied. A special detector measures the amount of absorbed radiation. This data is transformed by a computer into a digital image.
How to prepare for a CT Scan?
- You may be asked to wear a gown during the procedure.
- Wear clothing that is comfortable and easy to change.
- Please remove any jewelry, eyeglasses or any metal objects that are covering the area to be examined.
- You may be asked not to eat or drink for several hours prior to your procedure. We will give you instructions when you make your appointment.
- X-rays cannot be performed during pregnancy because of the potential harms to the fetus. Women should always notify the radiology technician of any possibility of pregnancy.
How does a CT Scan work?
CT uses a computer and a rotating x-ray device to create detailed, cross-sectional images, or slices, of organs and body parts.
As the scanner rotates, the detector takes numerous snapshots called “profiles.” Typically, about 1,000 profiles are taken in one rotation. Each profile is analyzed by computer, and the full set of profiles from each rotation is compiled into to form the slice-a two-dimensional image.
