Summary
The novel coronavirus disease (COVID-19) rapidly spread in China starting December 2019. This review examines chest computed tomography (CT) features and its emergency role for COVID-19.
Area of Science:
- Medical imaging
- Infectious diseases
- Pulmonology
Background:
- The novel coronavirus disease (COVID-19) emerged in December 2019.
- Rapid global dissemination of COVID-19 necessitates urgent diagnostic tools.
- Chest computed tomography (CT) is crucial in managing respiratory illnesses.
Purpose of the Study:
- To review the characteristic chest CT findings associated with COVID-19.
- To analyze the utility and significance of chest CT in the COVID-19 pandemic.
- To provide insights for radiologists and clinicians managing COVID-19.
Main Methods:
- Literature review of studies on COVID-19 chest CT features.
- Analysis of imaging patterns reported in confirmed COVID-19 cases.
- Synthesis of current evidence on the role of CT in diagnosis and monitoring.
Main Results:
- Common CT findings include ground-glass opacities, consolidation, and bilateral, peripheral distribution.
- CT can detect abnormalities even in asymptomatic or mildly symptomatic patients.
- The role of CT extends to assessing disease severity and progression.
Conclusions:
- Chest CT is a valuable tool for the early detection and assessment of COVID-19.
- Understanding CT features aids in differentiating COVID-19 from other pneumonias.
- CT plays a vital role in the clinical management of the COVID-19 health emergency.

01:20COPD: Pathogenesis and Clinical Features
1.7K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Chest Physiotherapy (CPT) is a therapeutic technique used in respiratory care to improve ventilation, clear bronchial secretions, and enhance the efficiency of respiratory muscles. This therapy includes three primary procedures: postural drainage, percussion, and vibration. It can be performed on spontaneously breathing patients and those who are intubated and mechanically ventilated.
Purpose
CPT is primarily used for patients with excessive bronchial secretions who have difficulty clearing...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.
