Imaging Studies for Cardiovascular System III: X-Ray

295
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

6.8K
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

6.0K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

161
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...

Area of Science:

  • Radiologic technology
  • Medical imaging appropriateness
  • Healthcare professional perceptions

Background:

  • Understanding factors influencing medical imaging appropriateness is crucial for optimizing patient care and resource allocation.
  • Radiologic technologists play a key role in the imaging process, and their perceptions can impact practice patterns.

Purpose of the Study:

  • To investigate how radiologic technologists' views on imaging appropriateness vary based on their primary imaging modality, work shift, shift length, and practice setting.
  • To identify specific reasons for inappropriate imaging and their correlation with technologist demographics and work environment.

Main Methods:

  • A national, cross-sectional study surveyed members of the American Society of Radiologic Technologists (ASRT).
  • Participants were randomized and employed in radiography, computed tomography (CT), mammography, or radiology leadership roles.
  • Seven potential reasons for inappropriate imaging were assessed against primary imaging modality, work shift, shift length, and practice type.

Main Results:

  • Perceptions of reasons for inappropriate imaging differed significantly across various factors.
  • Lack of time, patient expectations, and fear of lawsuits were associated with specific imaging modalities and practice types.
  • Compensation for insufficient clinical examination and fear of lawsuits showed strong correlations with imaging modality, work shift, and practice type.

Conclusions:

  • Radiologic technologists' perceptions of patient-centered and defensive medicine factors in imaging appropriateness are influenced by their work context.
  • Further research is needed to explore the underlying reasons for these perceptions and compare them with provider and evidence-based guideline perspectives.
  • Specific attention should be directed towards the appropriateness of computed tomography (CT) imaging procedures in hospital settings during night shifts.
