Lung injury in COVID-19 patients, severity on CT scan of COVID-19

Abstract

Introduction: COVID-19 is currently a great burden globally. Non-contrast computed tomography (CT) scan of the chest is increasingly important to detect lung abnormalities and monitor disease progression during treatment.

Objectives: To evaluate imaging characteristics of lung lesions on chest CT scan and the relationship of severity on CT scan and in clinical in COVID-19 patients.

Subjects and methods: Descriptive study on 530 patients with confirmed COVID-19 infection by RT-PCR technique from 01/08/2021 to 30/10/2021. The patient underwent non-contrast material chest CT scan for evaluation and classification. Score and severity on chest CT scan were evaluated quantitatively by imaging for a total of 25 points.

Results: The study recorded 70,8% of patients with lesions on CT scan of the chest. The most common form of lesions are pulmonary ground-glass opacity (GGO) (69,1%), bilateral (69,1%) and peripheral distribution (45,3%), multiple locations (63,2%). Compared with mild-moderate patients, in severe or critical patients, opacified, solidified, paved glass lesions, fibrous bands, bronchiectasis, and dilated blood vessels were predominant (p<0,05), distributed in many locations (p < 0,001), in the peripheral region of the lungs (p < 0,001). The study found that there was a statistically significant relationship between the clinical severity of the disease and the lesion score on the CT scan of the chest (p<0,001).

Conclusions: Two-thirds of patients with COVID-19 have lesions on non-contrast CT scan of the chest with diverse presentations, locations, and distribution. Patients with severe lung lesions on chest CT scan using TSS have a significant association with the clinical severity (p<0,001).
