Ultrasonography01:17

Ultrasonography

8.3K
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 Imaging01:24

X-ray Imaging

11.0K
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...

Computed Tomography01:10

Computed Tomography

9.4K
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...

Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

10.2K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies for Cardiovascular System III: X-Ray

600
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...

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...

Summary

Physician empathy and other psychometric traits did not predict computed tomography (CT) utilization in the emergency department (ED). Further research is needed to identify factors influencing physician CT ordering variation.

Area of Science:

  • Emergency Medicine
  • Radiology
  • Medical Education

Background:

  • Computed tomography (CT) utilization varies significantly among emergency physicians.
  • Physician empathy is a proposed factor influencing CT imaging decisions.
  • Understanding drivers of CT utilization is crucial for optimizing resource allocation.

Purpose of the Study:

  • To assess empathy levels in emergency physicians.
  • To determine the association between physician empathy and CT utilization.
  • To compare empathy's predictive power with other psychometric tests for CT use.

Main Methods:

  • Cross-sectional study analyzing ED CT utilization data (July 2013-June 2014).
  • Survey of emergency physicians using the Jefferson Scale of Empathy (JSE), Risk-Taking Scale (RTS), Stress from Uncertainty Scale (SUS), and Malpractice Fear Scale (MFS).
  • Hierarchical, mixed-effects regression model to evaluate associations between psychometric scores and risk-adjusted CT utilization.

Main Results:

  • 113,517 patients and 74 physician respondents were included; 18.5% received CT scans.
  • No statistically significant correlation was found between JSE scores and other psychometric scales.
  • No significant association was observed between performance on any psychometric scale and CT utilization.

Conclusions:

  • Physician empathy, risk-taking, stress from uncertainty, and malpractice fear do not predict risk-adjusted CT utilization in the ED.
  • Underlying physician-based factors driving CT utilization variation remain unidentified.
  • Further investigation is required to elucidate the determinants of interphysician variation in CT ordering.
