What is the difference between CT scanning and X -ray?
The differences between scanning computer tomography (CT) and X -ray are numerous and diverse, from the quality of the image created to the required amount of space for the location of the device. There are also significant differences between CT scanning and X -ray.
CT scan and X -ray differs greatly in the quality of the image produced. As an extension to X -ray technology, CT scans more X -ray images around the perimeter of the scanned body area. This technique leads to a bright three -dimensional image from CT scan versus often blurred image in a flat two -dimensional view created by X -ray. In addition to clearer displaying, more accurate images of specific areas or organs can also be achieved using CT scans than what can be seen with the X -ray.
The level of radiation exposure to the patient is the main perspective when the doctor decides between the need for CT scanning and X -ray. CT scans a much larger amount of radiation than X -rayrays, basically because CT scan is more of a number of X -rays than a single image. Increased radiation can put the patient in a category of higher risk for damage to cells if the exposure is excessive. Given this many doctors, it could only be decided to scan CT if it is absolutely necessary to make the correct diagnosis.
The size of the device between CT scanning and X -ray machine is another significant difference between two types of imaging devices. X -ray machines are relatively small and often easier to use than contrast CT scanning devices that are large and complicated for operation. Usually the patient would have to lie or stand before X -ray negative to create an image. CT technology requires the patient to enter a large cylindrical ring that rotates around the body to create an image. The technology used by radio -frager is also more demanding on CT scanthan an X -ray.
Due to the size and increased technological progress of CT scanning, the costs associated with the purchase, operation and housing are much higher than for the X -ray machine. CT scanning and X -ray are two pieces of equipment commonly observed in most hospitals or imaging equipment with higher CT scan costs. Both technologies may be the necessary diagnostic tools for healthcare workers. Any concerns about the need between CT scanning and X -ray should be addressed by a doctor.
