Insights

The novel coronavirus disease 2019 (COVID-19) diagnosis is critical for treatment. Chest CT scans complement real-time reverse transcription-polymerase chain reaction (RT-PCR) for better COVID-19 patient management.

Area of Science:

  • Medicine
  • Infectious Diseases
  • Radiology

Background:

  • The COVID-19 pandemic, caused by a novel coronavirus, rapidly spread globally.
  • Accurate diagnosis is essential for effective clinical management and treatment of COVID-19 patients.
  • The World Health Organization declared COVID-19 a major global health emergency.

Purpose of the Study:

  • To review and discuss the diagnostic criteria for COVID-19.
  • To highlight the main chest computed tomography (CT) features observed in COVID-19 patients.
  • To enhance understanding of COVID-19 and inform treatment strategies.

Main Methods:

  • Literature review of published studies on COVID-19 diagnosis and imaging.
  • Analysis of diagnostic criteria, focusing on real-time reverse transcription-polymerase chain reaction (RT-PCR).
  • Examination of chest CT findings reported in COVID-19 cases.

Main Results:

  • Real-time reverse transcription-polymerase chain reaction (RT-PCR) is the established diagnostic standard for COVID-19.
  • Chest CT findings can supplement RT-PCR results, offering additional diagnostic information.
  • Specific CT features are associated with COVID-19 pneumonia, aiding in diagnosis and assessment.

Conclusions:

  • Chest CT imaging plays a complementary role in the diagnosis of COVID-19.
  • Understanding CT features is crucial for clinicians managing COVID-19 patients.
  • This review synthesizes current knowledge on COVID-19 diagnosis and CT characteristics for improved patient care.

Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
