X-ray Imaging01:24

X-ray Imaging

10.9K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Imaging Studies for Cardiovascular System III: X-Ray

564
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...

Radiological Investigation I: X-ray and CT

1.4K
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...

Nuclear Power02:36

Nuclear Power

9.7K
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current01:14

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

1.5K
An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...

Biological Effects of Radiation02:59

Biological Effects of Radiation

18.8K
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...

    Area of Science:

    • Radiologic technology
    • Medical imaging
    • Radiation safety

    Background:

    • Gonadal and fetal shielding are standard radiation protection measures.
    • Current shielding practices may be evolving, particularly in abdominal and pelvic imaging.

    Purpose of the Study:

    • To determine if gonadal and fetal shielding are being eliminated during routine abdominal and pelvic imaging.
    • To compare shielding practices in abdominal/pelvic exams with other radiologic examinations.

    Main Methods:

    • A mixed-methods pilot study utilizing an anonymous 22-question survey.
    • Data collected from technologists via social media, cold calls, and professional networks over 31 days.
    • Survey focused on technologist demographics and shielding practices based on exam type, patient age, and sex.

    Main Results:

    • A high percentage of technologists reported not shielding during pelvic (95%), lumbar (82%), and torso (39%) imaging.
    • Patient age, sex, and the risk of covering anatomy significantly influence shielding decisions.
    • Most respondents (89%) had lap shields available, but employer protocols for sex-specific shielding were lacking for 64% of respondents.

    Conclusions:

    • Technologists' decisions to shield are influenced by factors beyond just patient radiation dose, including examination type and patient age.
    • Findings suggest a shift in shielding practices and provide a basis for reviewing current institutional protocols.
    • Further research is needed to understand the full implications of these evolving shielding practices.
