Use of Computed Tomography (CT) to Diagnose COVID-19

Ryan Gilgallon

Dr. Elaine Halesey, Ed.D., R.T.(R)(QM)

This project explains COVID-19 and the role Computed Tomography (CT) can play in diagnosing patients who have infections. General equipment used, symptoms, findings and abnormalities, methods of early detection, rates of misdiagnosis, advantages of CT, and a case study are also discussed. COVID-19 originated in Wuhan, China and rapidly spread throughout the world being transmitted from human to human, affecting the respiratory system. The most common findings in this project consisted of ground-glass opacities (GGO), fibrous stripes, interlobular septal thickening, and consolidation. Computed Tomography is a non-invasive procedure which is effectively used to detect, treat, manage, and track recovery of patients infected. With a low misdiagnosis rate of 3.8% and early detection of 2.61 days compared to RT-PCR test result, it proves that CT is an accurate tool to diagnose COVID-19. As technology advances, infections such as COVID-19 can be managed and treated through the use of Computed Tomography.
