Computed Tomography A CT scan is produced using plenty of x-ray images from lots of different angles using computerized axial tomography (cat). It produces cross-sectional images or slices of bones, tissues and the angio portion which is produced through a CTA (cat scan angio) allows professionals to view the blood vessels. It is a great medical tool, with interesting history and of course like everything else in the worldwide medicine, it has its pros and cons. A Computed Tomography scan is a form of preventive medicine and screening to discover diseases, internal injuries as well as to come up with radiology related treatment plans and trauma related treatment plans. It is used in plenty of hospitals medical and trauma and a lot of outpatient

In the early 1900s an Italian radiologist by the name of Alessandro Vallebona was the first one to propose a method to represent a single slice of the body on radiologic film developed on principles of projective geometry (Li, 2013). Throughout the 1900s it was used for practical research etc , but in 1971 in the United Kingdom engineer Sir Godrey Hounsfield and Africa-born physicist Alan Cormack invented the first commercially viable CT scanner in the world. Interesting fact is that they never actually met until their Nobel peace prizes were awarded to them. The very scanner took about 2 hours to produce 1 slice, but nowadays 4 slices can be produced in less than 1 second due to the amazing improvements in speed, quality, technology and comfort. Through the great technological and research improvements high quality images are able to be produced at the lowest possible radiation dose which helps patients avoid other related diseases brought on by radiation exposure and helps retain cancer risk to their lowest possibility. Cormack and Hounsfield were awarded a Nobel peace prize in 1979 for their contributions to medicine and science (LA times, …show more content…
CT can for sure detect life threatening conditions but there is radiation risk so it is prudent as a patient to keep track of how often they are produced and to speak up against one when you have to. There is a chance that it can cause the cancer in a patient to spread even more because 6 percent of x-rays done are CT's but 40 percent of radiation created from x-ray technology alone comes from CT's so it is a big risk (The press and journal, 2007). Patients who have an allergic reaction after contrast is administered can be allergic to two things, shellfish and or iodine. Hopefully the reaction that occurs or is encountered is mild but it can be severe at times. Severe iodine reactions are usually accompanied by urticaria, dyspnea, dizziness and confusion can sometimes happen
