abstract ={In 21st century, the year 2020 was expected with much development in India as well many other countries.
But unfortunately, the world is facing many natural calamities. World is taking steps towards rescue mission
of the disasters. Among of those calamities, deadly Corona Virus remains still all over the world as pandemic
disease. Even the developed countries are struggling to come back to its normal routine. India is a country
with developing technologies. Vaccines are yet to be developed for treatment of this Novel Corona Virus.
As a diagnostic tool, Nasopharyngeal and Oropharyngeal swabs are taken from the person and tested using
RT-PCR. This test is not 100 percent accurate. Confirmed COVID patients after few days are undergoing
the medical imaging. This diagnostic imaging technique helps in showing the progression of this virus
spread in Upper and Lower respiratory system. Chest Radiography is low cost modality but its sensitivity
towards observation is 69%. Lung Ultrasound is used in Intensive Care patients and not used for routine
diagnosing purpose. Computed Tomography plays a crucial role in three-dimensional chest imaging of
COVID-19 patients. The sensitivity of CT is 98%. The aim of this paper is to consider CT as a tool for
diagnosing COVID-19 patient than using the standard tool RT-PCR. A brief knowledge about imaging
modality like X-ray, Ultrasound and Computed Tomography when used against COVID patient is
explained. This paper gives reason for the ideal use of CT diagnosis for COVID 19.}
