Summary
Computed tomography (CT) scans are a major source of radiation exposure. This review clarifies CT radiation nomenclature, dosimetry, and risks for medical practitioners to better inform patients about scan benefits and risks.
Area of Science:
- Radiology
- Medical Physics
- Public Health
Background:
- Medical imaging, particularly computed tomography (CT), significantly contributes to per capita radiation dose in the United States.
- Over 62 million CT scans are performed annually, increasing public awareness and concern regarding radiation exposure risks.
Purpose of the Study:
- To inform medical practitioners about the nomenclature, dosimetry, and estimated risks associated with CT scan radiation exposure.
- To enable clinicians to better assess the risks and benefits of CT imaging.
- To equip healthcare providers to address patient concerns about radiation risks.
Main Methods:
- Literature review on CT radiation exposure.
- Analysis of current nomenclature and dosimetry standards.
- Synthesis of data on estimated health risks from CT scans.
Main Results:
- CT procedures represent a substantial portion of medical radiation dose.
- Understanding radiation nomenclature and dosimetry is crucial for risk assessment.
- Estimated risks are presented to aid clinical decision-making.
Conclusions:
- Medical practitioners need clear information on CT radiation to manage patient care effectively.
- Informed discussion of risks and benefits is essential for responsible CT utilization.
- This review provides a foundation for addressing patient questions regarding CT radiation exposure.

01:10Computed 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...

01:30Radiological 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 the...
02:59Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
01:27Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:25Imaging 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...
01:28Imaging 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...
