A critical review on medical imaging techniques (CT and PET scans) in the medical field

Abstract

Abstract About a century ago, doctors were unable to view the inside of their patient’s body other than cutting the body open. However, this changed literally upon the invention of various useful medical imaging techniques, which were able to produce images of the internal organs and bones without causing pain to the patient. Over the years, vast developments resulted in the establishment of several cross-sectional imaging scans. This paper aims to provide a critical review on the use of two of the famous techniques; CT and PET scans. The paper highlights the strengths and weaknesses of each of these techniques along with briefly mentioning the recent developments in this area concerning the use of these techniques. In addition, this manuscript also sheds some light on the novel and hybrid technology of integrating CT and PET.
