Imaging Studies I: CT and MRI01:14

Imaging Studies I: CT and MRI

557
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

227
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 for Cardiovascular System III: X-Ray

332
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 Imaging01:24

X-ray Imaging

9.0K
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...

Ethical Standards II01:23

Ethical Standards II

993
Ethical standards are the backbone of nursing practice, guiding nurses as they interact with patients, families, and colleagues. These standards are crucial for providing safe, empathetic care centered on the patient's needs.
Nurses are entrusted with upholding various ethical principles and standards. Nurses forge solid therapeutic relationships using trust, empathy, autonomy, confidentiality, and professional competence.
Confidentiality is crucial, embodying respect for individual privacy...

Area of Science:

  • Medical Imaging
  • Radiation Safety
  • Radiography

Background:

  • Gonadal shielding has been a standard practice in diagnostic radiography for decades.
  • Emerging evidence suggests potential harms, including obscured anatomy and increased radiation dose from repeat imaging.
  • Western institutions have largely discontinued routine shielding, while it remains common in Asia.

Purpose of the Study:

  • To discuss the benefits and drawbacks of gonadal shielding in diagnostic imaging.
  • To establish a pan-Asian consensus on shielding practices.
  • To address country-specific and cultural factors influencing shielding decisions in Asia.

Main Methods:

  • A dedicated session on shielding was held during the 2020 Asia-Pacific Forum on Quality and Safety in Medical Imaging (APQS) meeting.
  • Radiation safety and imaging quality experts from various Asian regions participated.
  • Discussions focused on current opinions and practices regarding gonadal shielding.

Main Results:

  • Experts' views largely aligned with Western radiologists' skepticism towards routine shielding.
  • Significant country-specific and cultural factors influencing shielding practices were identified.
  • A pan-Asian consensus statement on shielding was developed and issued.

Conclusions:

  • The consensus aims to inform and guide the future development of shielding policies across Asia.
  • Re-evaluation of routine gonadal shielding is warranted, considering potential risks and benefits.
  • Cultural context is crucial when establishing imaging safety guidelines in diverse regions.
