Abstract
COVID-19 related pneumonia could be greatly diagnosed using chest CT imaging, The clinical presentation, course, and outcome of COVID-19 are heterogeneous, and this also applies to the degree of pulmonary involvement.
Performing chest CT in patients with suspected COVID-19 infection is recommended. Several chest CT features are commonly seen in COVID-19 (including ground-glass opacities and consolidation, vascular enlargement, bilateral abnormalities, lower lobe involvement, and posterior predilection), whereas others are not, and this may help in diagnostic decision making.
In our study; Sixty patients, each patient gave informed consent and the study was approved by the local ethics committee, the patients were 50 female and 30 male patients, with age range 26-72 years, all underwent chest CT, all had clinical symptoms varying between cough 70%, fever 60%, dyspnea 40%, myalgia 28.3%, nausea 13.3%, and diarrhea 16.7%; diagnosed as suspected suffering from COVID-19 related pneumonia.
Description of PSI (pneumonia severity index) group in all studied patients, It was group I in 12 patients (20%), group II in 26 patients (43.3%),group III in 13 patients (21.7%) and group IV in 9 patients (15%), as goups I and II are considered low risk groups, group III is considered imtermediate risk goup while groups IV and V are considered high risk groups.
The most common chest radiographic findings are GGO and pulmonary consolidation, with prominent distribution in the posterior and peripheral part of the lungs. chest CT scans had uniformed results which point to the diagnosis
