Biological Effects of Radiation02:59

Biological Effects of Radiation

17.6K
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...

X-ray Imaging

9.7K
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...

Mutations

42.6K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

387
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:

  • Medical Imaging
  • Paediatric Orthopaedics
  • Radiation Safety

Background:

  • Fluoroscopy is essential in paediatric orthopaedic surgery, but national radiation exposure benchmarks are absent.
  • Establishing local diagnostic reference levels (DRLs) is crucial for practice evaluation and patient safety.
  • This study quantifies intraoperative radiation exposure in common paediatric orthopaedic procedures.

Purpose of the Study:

  • To establish local reference ranges for intraoperative fluoroscopy radiation exposure.
  • To benchmark current radiation exposure practices in paediatric orthopaedic surgery.
  • To provide data supporting the development of national DRLs.

Main Methods:

  • Retrospective observational study of 480 paediatric (<18 years) orthopaedic procedures over four years.
  • Procedures categorized by anatomical region (elbow, ankle, pelvis) and type (MUA, MUA with K-wire, ORIF).
  • Fluoroscopy radiation exposure (mGy/cm²) recorded and analyzed using descriptive statistics and Mann-Whitney U tests.

Main Results:

  • Slipped upper femoral epiphysis (SUFE) pinning showed the highest mean exposure (384.5 mGy/cm²).
  • Open reduction and internal fixation (ORIF) had highest elbow exposure (13.9 mGy/cm²); MUA with K-wire fixation had highest ankle exposure (12.4 mGy/cm²).
  • MUA with K-wire procedures demonstrated significantly higher radiation exposure than simple MUA in elbow and ankle procedures (p < 0.001).

Conclusions:

  • This study provides the first detailed local reference ranges for intraoperative fluoroscopy in paediatric orthopaedics.
  • Significant procedure-specific variability in radiation exposure was observed.
  • Findings support the development of local DRLs, promoting safer practices and national standardisation.
