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

Imaging Studies for Cardiovascular System III: X-Ray

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...
Biological Effects of Radiation02:59

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Radiological Investigation I: X-ray and CT

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 the...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Summary

Physicians performing fluoroscopically-guided procedures receive radiation doses comparable to interventional cardiologists. Optimizing protocols and protective measures can significantly reduce occupational radiation exposure for these medical specialists.

Area of Science:

  • Medical Physics
  • Occupational Health
  • Interventional Radiology

Background:

  • Fluoroscopically-guided (FG) procedures have significantly increased over the last 30 years.
  • Radiation exposure to physicians performing these procedures is a growing concern.
  • Previous studies primarily focused on cardiologists, leaving other specialists underrepresented.

Purpose of the Study:

  • To estimate radiation doses received by non-cardiologist physicians performing FG procedures.
  • To identify specific FG procedures with substantial operator radiation exposure.
  • To compare these doses with those received by interventional cardiologists.

Main Methods:

  • Systematic literature search of Medline for English-language articles on physician radiation exposure.
  • Identification of therapeutic FG procedures with at least five published dose reports, frequent performance, and multiple specialties involved.
  • Abstraction of radiation dose data and estimation of effective dose to operators.

Main Results:

  • Seven procedures were analyzed: PCNL, vertebroplasty, orthopedic extremity nailing, biliary tract procedures, TIPS, head/neck endovascular procedures, and ERCP.
  • Estimated effective doses per case varied widely across procedures, with some reaching up to 101 microSv.
  • Mean operator radiation doses measured at eye, neck, and trunk levels ranged from 19-800, 6-1,180, and 2-1,600 microSv, respectively, with hands often receiving higher doses.

Conclusions:

  • Physician specialists performing FG procedures receive radiation doses comparable to interventional cardiologists.
  • Significant variations in operator doses highlight the potential for reduction through protocol optimization and protective device use.
  • Implementing enhanced safety measures is crucial for minimizing occupational radiation risks in interventional procedures.
