Cancer Prevention02:59

Cancer Prevention

6.5K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Computed Tomography01:10

Computed Tomography

7.6K
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 Investigation I: X-ray and CT

1.8K
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...

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...

Imaging Studies for Cardiovascular System V: CT

671
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...

Area of Science:

  • Radiology and Imaging
  • Pediatric Oncology
  • Radiation Epidemiology

Background:

  • Increasing use of pediatric computed tomography (CT) scans raises concerns about ionizing radiation exposure.
  • Comparison with non-ionizing imaging modalities highlights potential risks.
  • This review focuses on factors leading to repeat pediatric CT scans and their cancer risk association.

Purpose of the Study:

  • To systematically review factors contributing to repeat CT scans in children.
  • To assess the association between pediatric CT scans and cancer risk.
  • To inform the development of pediatric CT guidelines.

Main Methods:

  • Comprehensive literature search across Web of Science, Scopus, and PubMed.
  • Inclusion of 30 eligible studies.
  • Meta-analysis of five studies involving over seven million participants.

Main Results:

  • CT exposure significantly increased overall cancer risk (RR = 1.49).
  • Elevated risk observed for brain tumors (RR = 1.55); leukemia risk was less conclusive (RR = 1.23).
  • A dose-response relationship was evident: two or more CT scans significantly increased cancer risk (RR = 2.51) compared to one scan (RR = 1.07).

Conclusions:

  • Results underscore the necessity for practical pediatric CT guidelines.
  • Recommendations include performing CT scans only when clinically justified, using low-dose protocols, and considering non-ionizing alternatives.
  • Future research should focus on evidence-based recommendations balancing diagnostic utility with long-term radiation risks in pediatric imaging.
