Summary
Chest CT scans show high sensitivity for detecting COVID-19 pneumonia, aiding early diagnosis and management. This review details typical and atypical computed tomography findings for severe acute respiratory syndrome coronavirus 2 infection.
Area of Science:
- Radiology
- Infectious Diseases
- Pulmonology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a disease with common symptoms like fever and cough.
- The gold standard for SARS-CoV-2 diagnosis is RT-PCR, but chest CT offers high sensitivity for pneumonia detection.
Purpose of the Study:
- To review and illustrate the typical and atypical computed tomography (CT) findings associated with COVID-19 pneumonia.
- To highlight the role of radiologists in identifying suspicious CT features of COVID-19.
Main Methods:
- Review of scientific literature on chest CT findings in COVID-19 patients.
- Compilation of characteristic and unusual imaging patterns observed on CT scans.
Main Results:
- Typical CT findings include bilateral ground-glass opacities, consolidations, septal thickening, and crazy paving patterns.
- Atypical findings encompass halo signs, reversed halo signs, cavitation, and pleural effusions.
- The frequency of lymphadenopathy and bronchiectasis in COVID-19 pneumonia remains unclear.
Conclusions:
- Chest CT is a valuable tool for the early detection, management, and follow-up of COVID-19 pneumonia.
- Radiologists are crucial in recognizing both typical and atypical CT findings suggestive of COVID-19.

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...

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...

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...
