| Summary: | Background: To analyze the chest computed tomography (CT)
features in patients with coronavirus disease 2019 (COVID-19)
pneumonia.
Methods: This was a prospective descriptive study comprising
202 consecutive reverse transcriptase polymerase chain
reaction (RT-PCR) positive patients who underwent CT chest.
For 25 patients, follow-up CT scans were obtained. The CT
images were evaluated for the number, type and distribution
of the opacity, and CT severity scoring was done
Results: Among the total study cohort of 202 patients, 152
were males and 50 were females .From July 07, 2020, to
september07, 2020, totally 202 laboratory-confirmed patients
with COVID-19 underwent chest CT. For 25 patients, follow-up
CT scans were obtained. The CT images were evaluated for the
number, type and distribution of the opacity, and the affected
lung lobes. Furthermore, the initial CT scan and the follow-up
CT scans were compared. Results were patients (98.5%) had
two or more opacities in the lung and 3 (1.5%) patients has
negative chest CT. 183 (90.6%) patients had only ground-glass
opacities; 13 patients (6.4%) had ground-glass and
consolidative opacities; and 3 patients (1.5%) had only
consolidation. A total 192 of patients (96.5%) showed two or
more lobes involved. The opacities tended to be both in
peripheral and central 7 (3.5%) or purely peripheral distribution
192 (96.5%). 177 patients (88.9%) had the lower lobe involved.8
patients showed complete resolution of lung findings.
Conclusion:
In this study population, the typical CT features of COVID
19 pneumonia are ground glass opacity with or without
consolidation, which is patchy and peripheral, predominantly
in lower lobes. |
