Biological Effects of Radiation02:59

Biological Effects of Radiation

15.5K
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...

Radiological Investigation I: X-ray and CT

238
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...

Transmission-based Precautions II: Airborne and Protective Environment

1.3K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

92
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...

X-ray Imaging01:24

X-ray Imaging

5.5K
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

119
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Medical Imaging
  • Radiology
  • Critical Care Medicine

Background:

  • Radiological imaging is indispensable for managing acute patients in Intensive Care Units (ICUs).
  • Ionizing radiation exposure from these procedures poses significant health risks.
  • The COVID-19 pandemic exacerbated radiation exposure due to increased imaging frequency.

Purpose of the Study:

  • To review and synthesize research on radiation exposure in ICU settings.
  • To analyze radiation safety thresholds and patient cumulative doses.
  • To explore dose-reduction strategies for critical care imaging.

Main Methods:

  • Systematic review of existing literature on radiological imaging in ICUs.
  • Analysis of radiation exposure data and safety thresholds.
  • Evaluation of prospective studies on cumulative effective doses.

Main Results:

  • Some ICU patients exceed diagnostic reference levels for radiation exposure.
  • A rise in median cumulative effective dose is observed in trauma patients over time.
  • Innovative dose-reduction strategies show promise, especially in neuro-ICUs.

Conclusions:

  • Radiological imaging in critical care is essential but carries inherent radiation risks.
  • Rigorous radiation management protocols are necessary to protect patients.
  • Balancing diagnostic needs with long-term health risks is paramount.
