Computed Tomography

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...

Radiological Investigation I: X-ray and CT

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...

Imaging Studies I: CT and MRI

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Background:

The COVID-19 pandemic necessitates improved detection rates for effective control.
Computed tomography (CT) is increasingly utilized as an auxiliary screening tool for COVID-19.
This meta-analysis systematically evaluates the real-world performance of CT in COVID-19 screening.

Approach:

A comprehensive literature search was conducted across major databases (Web of Science, PubMed, Embase, etc.) up to September 1, 2022.
Data from 115 studies involving 51,500 participants were included.
Key diagnostic metrics such as sensitivity, specificity, AUC, and dOR were calculated.

Key Points:

Pooled AUC for CT in confirmed and suspected COVID-19 cases were 0.76 and 0.85, respectively.
Diagnostic odds ratio (dOR) for CT was 5.51 in confirmed cases and significantly higher at 13.12 in suspected cases.
CT demonstrates substantial diagnostic accuracy for identifying COVID-19 infection.

Conclusions:

Computed tomography (CT) serves as a valuable auxiliary screening method for COVID-19.
CT exhibits higher diagnostic efficacy in suspected COVID-19 cases.
These findings support the integration of CT into real-world COVID-19 diagnostic strategies.
