Objectives:
To identify a correlation between the clinical parameters and CT chest severity score in COVID-19.
Methods:
A total of 205 RT-PCR positive patients were included in this descriptive cross-sectional study with convenience sampling from November 2020 to June 2021 in KRL Hospital. The study population was stratified in disease severity as per the WHO's guidelines. Clinical and radiological characteristics were compared in survivors and non survivors to draw conclusion.
Results:
The mean age was 57 years and the majority of the patients 57% were male. Overall mortality was 22% and the mean CT severity score was 18. Non survivors were more tachypneic, hypoxic, had a higher CT chest severity score, higher clinical severity, more comorbid condition and higher TLC, D-Dimers, LDH, CRP, NLR. Raised CT severity score showed a conclusive correlation with greater disease severity. One way ANOVA showed a significant difference between mean CT severity score amongst different disease categories.
Conclusion:
Higher CT severity score corresponds to a higher clinical severity and higher chances of mortality.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
