FINDINGS OF COMPUTER AIDED CHEST TOMOGRAPHY FOR DETECTION OF PANDEMIC IN YOUNG AND ADULTS. A SYSTEMIC REVIEW

Abstract

Objectives: In this study, we aim to explore all literature that was done on the Covid patients with regards to CT imaging. We aim to explore the variations in CT imaging which occurs at different time intervals with changes in the frequency of CT features.

Methodology: For this study, we follow the Preferred Reporting Items guideline for conducting this systematic review analysis (PRISMA) 16. We search electronic articles from January to April on PUB Med, online Willey library, and ScienceDirect site by using keywords related to CT imaging and Corona virus.

Results: After pooling data, we observed that bilateral involvement was found in 76.8% of studies, 68.4% GCO, and 62.2% ratio was occupied by peripheral distribution in different studies. 48.7% of studies were concerned about the GCO consolidation, 33.2% observed consolidation, 27.7% ratio of crazy paving pattern, and 25% of studies observed mixed central and peripheral distribution. Only 15.2% of studies observed unilateral involvement and 9.2% of studies were concerned with the nodular opacity feature whereas a very little amount of literature was found on lymphadenopathy (2.4%).

Conclusion: This systematic literature review has some limitations. We did not find studies that have the same interval between CT imaging and symptoms onset. Some researchers performed CT after 2 weeks of symptoms and some performed before 2 weeks.
