Abstract
Acute respiratory distress syndrome (ARDS) is a life-threatening disorder marked by low oxygen levels and rigid or non-compliant lungs. In the absence of any indication of cardiogenic pulmonary edema, ARDS is defined as an acute disease that begins within 7 days of the triggering event and is marked by bilateral lung infiltrates and severe progressive hypoxemia. ARDS has a significant death rate, and there are few effective treatment options for this life-threatening illness. The management of these severely ill patients in the intensive care unit relies heavily on imaging. Chest radiography, bedside lung ultrasonography, and computed tomography scans can all help with patient care and prognostic variables identification. However, imaging results are not always specific, and other diagnosis should be considered.

Lesions in COVID19 lung disease are more likely to be bilateral, lower lung predominant, and multifocal as the disease progresses. They frequently have the appearance of rounded opacities, which are referred to as "COVID balls." The extent of lung involvement increases as ARDS progresses, and there is a consolidative component [5]
Summary
Acute respiratory distress syndrome (ARDS) is a life-threatening disorder marked by low oxygen levels and rigid or non-compliant lungs. When comparing COVID19 pneumonia in China to viral pneumonia in the United States, the most distinguishing features included a peripheral distribution of opacification, frosted glass opacities, and vascular thickening or enlargement [5] These imaging features appear to be typical of COVID19 pneumonia and can aid in the early screening of highly suspected cases as well as the assessment of disease severity and extent. Lesions in COVID19 lung disease are more likely to be bilateral, lower lung predominant, and multifocal as the disease progresses They frequently have the appearance of rounded opacities, which are referred to as "COVID balls." The extent of lung involvement increases as ARDS progresses, and there is a consolidative component [5]. When the PaO2/FIO2 ratio is less than 200 mm Hg, as compared to 300 mm Hg in ALI, the condition is referred to as ARDS. ARDS is rapidly being recognized as a heterogeneous illness, prompting efforts to find clinical and molecular characteristics that might be used to divide individuals into sub phenotypes that may respond better to certain medications [8]
