Ultrasonography01:17

Ultrasonography

4.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

X-ray Imaging

5.4K
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...

Computed Tomography01:10

Computed Tomography

4.3K
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

3
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...

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 III: X-Ray

143
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...

Summary

Defining low-value imaging is crucial for improving healthcare. Low-value imaging offers more harm than benefit, failing to reduce patient pain or suffering, and may not alter clinical management or be cost-effective.

Area of Science:

  • Medical Imaging
  • Health Services Research
  • Clinical Decision Making

Background:

  • The concept of low-value imaging lacks a universally agreed-upon definition.
  • A clear definition is essential for targeted research and enhancing imaging service quality, safety, effectiveness, efficiency, and sustainability.

Purpose of the Study:

  • To establish a precise and applicable definition for low-value imaging.

Main Methods:

  • A comprehensive review of existing definitions of low-value care and practical measures of low-value imaging.
  • Application of standard concept analysis criteria (precision, non-circularity, applicability, justification, distinctability).
  • Validation of the proposed definition using practical examples and tasks.

Main Results:

  • Low-value imaging is defined as imaging that does not alleviate patient pain, dysfunction, or suffering compared to alternatives.
  • Such imaging may yield more harm than benefit, fail to change clinical management, or lack cost-effectiveness.
  • The proposed definition meets general criteria, is applicable to real-world scenarios, and distinguishes valuable from non-valuable imaging.

Conclusions:

  • A clear and consistent definition of low-value imaging has been established.
  • This definition is vital for improving the quality, safety, effectiveness, efficiency, and sustainability of medical imaging.
  • The definition effectively differentiates between valuable and non-valuable imaging procedures.
