Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

466
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...

284
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies for Cardiovascular System V: CT

284
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Upper GI Series: Barium Swallow

1.5K
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Radiological Investigation I: X-ray and CT

1.1K
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...

Summary

Personnel performing videofluoroscopic swallow studies receive higher radiation doses when closer to the source. Rotating roles can minimize occupational radiation exposure for staff involved in veterinary fluoroscopy.

Area of Science:

  • Veterinary Radiology
  • Diagnostic Imaging
  • Radiation Safety

Background:

  • Contrast-enhanced videofluoroscopic swallow studies are essential for diagnosing dysphagia in animals.
  • These procedures involve fluoroscopy and expose personnel to ionizing radiation.

Purpose of the Study:

  • To quantify radiation exposure in personnel during veterinary fluoroscopic swallow studies.
  • To compare exposure based on disease location and resident experience.
  • To identify high-risk positions for radiation exposure.

Main Methods:

  • A prospective observational study of 61 animals (dogs and cats) undergoing fluoroscopic swallow studies.
  • Radiation dose was measured for different personnel positions (feeding, restraining, image acquisition).
  • Data analyzed using a linear mixed effects model, considering fluoroscopy time and disease location.

Main Results:

  • Personnel position significantly impacted radiation dose (p < 0.001).
  • Fluoroscopy time was also a significant factor (p = 0.005).
  • Radiation dose did not significantly differ based on anatomic disease location (p = 0.438).
  • The highest median dose was for personnel feeding patients (48.13 µSv), lowest for image acquisition (16.38 µSv).

Conclusions:

  • Personnel proximity to the radiation source directly correlates with radiation dose.
  • Veterinary staff should be aware of occupational radiation hazards during these studies.
  • Rotating personnel roles can effectively reduce cumulative radiation dose for individuals.
