Objective:
To evaluate the laboratory confirmed COVID-19 pneumonia and correlate the findings obtained by thorax ultrasound (USG) and thorax computed tomography (CT).
Study Design:
Observational study.
Place And Duration Of Study:
Departments of Infection Disease, Internal Medicine and Radiology, Sakarya Training and Research Hospital, Sakarya, Turkey, between March and May 2020.
Methodology:
This study was consisted of 100 adult patients having rRT-PCR positive COVID-19 pneumonia diagnossed by thorax CT. The clinical features, thorax USG and CT findings of these patients were recorded and expressed. USG and thorax CT findings were scored using a method described before. Continuous variables were expressed as mean (±SD) values. The Kolmogorov-Smirnov test was used for the normal distribution test, and continuous variables were compared using the Mann-Whitney U test. USG and CT performed at time of admission to the hospital. Descriptive statistics were conducted based on the structures of variable.
Results:
A total of 100 patients (54 men and 46 women; mean age, 59.88±13.03 years; range, 28-91years) with COVID-19 pneumonia were evaluated. Involvement areas on the lower posterior of the right side were detected as 70% by ultrasound and 74% by CT. Positively correlation was detected in lung scans assessed by USG and CT (p<0.001, r=0.705).
Conclusion:
Ultrasound has several advantages including no ionizing radiation exposure for health care workers, being a safe, fast and non-invasive diagnostic technique with bedside usage. Hence, ultrasound is an efficient alternative to diagnosis and monitor of patients with COVID-19 pneumonia. Key Words: COVID-19, Lung ultrasound, Pneumonia, RRT-PCR.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
