CT scan has a lot of potential benefits compared to X-rays. It is far more advanced than any other scanning technology in the medical field. CT scan is usually a chosen method by doctors for diagnosing different cancers commonly lung, liver, and pancreatic cancer because the image permits the physician to detect the tumor and measure its size. CT scan can show the exact location of the tumor and reveals other tissues that are affected by the tumor. It plays an important role in detecting, diagnosing and treating diseases that can lead to serious problems, including stroke, kidney failure, and death. It can also treat bone injuries because very small bones and the tissues around it can be seen clearly (RadiologyInfo, 2009).

CT scan is an easy procedure because the results are accurate and invasive, therefore, it’s painless. One of its great advantages is that it’s able to let the physician view bones, tissues, and blood vessels at the same time. It also gives detailed information about a person’s body compared to a conventional X-ray. CT scan is fast in revealing internal injuries and bleeding, giving the doctors enough time to save the patient’s life. The scan can be performed even if a patient has an implanted medical device of any kind, and there’s no radiation left in the patient’s body after the examination. X-rays used in CT scans usually don’t have side effects (RadiologyInfo, 2009).
