Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

1.5K
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 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...

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

574
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies I: CT and MRI

1.1K
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...

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...

    Area of Science:

    • Radiological physics
    • Medical imaging
    • Radiation protection

    Background:

    • Minimizing radiation dose to reproductive organs is crucial in diagnostic imaging.
    • Gonadal shielding practices can vary, leading to inconsistent radiation protection for male patients.

    Purpose of the Study:

    • To quantify the radiation dose reduction to phantom testes when using a flat contact shield during pelvic radiography.
    • To evaluate the effectiveness of gonadal shielding in reducing testicular radiation exposure.

    Main Methods:

    • A male anthropomorphic pelvis phantom was utilized for imaging.
    • Thermoluminescent dosimeters (TLDs) were placed in the phantom's testes locations.
    • Pelvic imaging was performed with and without a flat contact shield, with ten exposures for each condition.

    Main Results:

    • A statistically significant reduction in radiation dose to the testes was observed when shielding was applied (t test, F = 8.306, P < .006).
    • Utilizing a flat contact shield resulted in a 36.4% decrease in radiation exposure to the testes compared to unshielded imaging.

    Conclusions:

    • Flat contact shielding is an effective method for significantly reducing radiation dose to the testes during adult male pelvic imaging.
    • Despite literature discrepancies, routine gonadal shielding for adult males undergoing pelvic radiography is recommended as a best practice.
