Insights

The study identified typical radiological features of Coronavirus disease 2019 (COVID-19) using chest CT scans. Key findings include scattered bilateral ground-glass opacities, fever, and cough, aiding early diagnosis and progression assessment.

Area of Science:

  • Radiology
  • Infectious Diseases
  • Pulmonology

Background:

  • Coronavirus disease 2019 (COVID-19) is a global health concern.
  • Understanding its radiological manifestations is crucial for diagnosis and management.

Purpose of the Study:

  • To describe the typical radiological features and progression of COVID-19 patients.
  • To correlate imaging findings with clinical and laboratory data.

Main Methods:

  • Retrospective review of chest CT scans, laboratory findings, and clinical records.
  • Analysis of 66 COVID-19 patients admitted between January 21 and February 2, 2020.
  • Evaluation of lesion characteristics, lobe involvement, and comorbid conditions.

Main Results:

  • Predominant symptoms included fever (91%) and cough (56%).
  • Typical CT findings were scattered, bilateral ground-glass opacities (97%) with air bronchogram sign (71%).
  • More than two lobes were involved in 73% of patients, with lower lobes most affected.

Conclusions:

  • Typical radiological features of COVID-19 include scattered ground-glass opacities in bilateral lobes.
  • Fever and cough are major clinical symptoms.
  • Integrating chest CT, clinical symptoms, and lab results aids early COVID-19 diagnosis and progression monitoring.

COPD: Pathogenesis and Clinical Features

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Stages of Infection01:26

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...
