Summary
Computed tomography scans revealed that coronavirus disease 2019 (COVID-19) infection did not correlate with paranasal sinus opacification. However, COVID-19 positive patients reported more nasal congestion.
Area of Science:
- Radiology
- Infectious Diseases
- Otolaryngology
Background:
- Sinus imaging is crucial for diagnosing various conditions.
- The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on paranasal sinuses requires further investigation.
Purpose of the Study:
- To analyze computed tomography (CT) scans of paranasal sinuses in patients with coronavirus disease 2019 (COVID-19).
- To correlate CT findings with COVID-19 status and clinical symptoms.
Main Methods:
- CT scans of 95 adult patients tested for SARS-CoV-2 were analyzed.
- Paranasal sinus opacification was graded and compared between SARS-CoV-2 positive and negative groups.
- Clinical data, including nasal congestion, were collected.
Main Results:
- No significant difference in paranasal sinus opacification scores was found between COVID-19 positive and negative patients.
- Mucosal thickening was prevalent across all paranasal sinuses, regardless of SARS-CoV-2 status.
- Nasal congestion was reported more frequently in SARS-CoV-2 positive individuals (p=0.05).
Conclusions:
- SARS-CoV-2 infection is not associated with paranasal sinus opacification on CT scans.
- Patient-reported nasal congestion may be linked to SARS-CoV-2 infection.
- CT imaging of paranasal sinuses is unlikely to be a primary diagnostic tool for COVID-19.

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...

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...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

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...
