Computed Tomography01:10

Computed Tomography

9.7K
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...

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...

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...

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...

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...

Area of Science:

  • Pulmonology
  • Radiology
  • Preventive Medicine

Background:

  • The National Lung Cancer Screening Trial demonstrated survival benefits of low-dose CT scans for high-risk individuals.
  • This led to recommendations for annual screening in at-risk populations.

Purpose of the Study:

  • To review the risks associated with lung cancer screening using low-dose CT scans.
  • To inform discussions about patient enrollment by weighing risks against benefits.

Main Methods:

  • Review of risks associated with low-dose CT screening.
  • Analysis of potential harms including radiation exposure, false positives, and overdiagnosis.

Main Results:

  • Key risks include radiation exposure, false-positive results leading to unnecessary procedures, overdiagnosis, overtreatment, and psychological distress.
  • These risks are less characterized than the survival benefits.

Conclusions:

  • The benefits of lung cancer screening must be carefully weighed against identified risks.
  • Informed patient discussion is crucial for enrollment decisions.
