This study details eight safety concerns in clinical magnetic resonance (MR) imaging, covering biologic, projectile, gradient, radio-frequency, auditory, superconductive system, psychological, and contrast agent effects.

Area of Science:

  • Medical Imaging
  • Biophysics
  • Radiological Safety

Background:

  • Clinical magnetic resonance (MR) imaging utilizes powerful magnetic fields and radio-frequency pulses.
  • Ensuring patient safety during MR procedures is paramount.
  • Potential risks associated with MR imaging require thorough evaluation.

Purpose of the Study:

  • To identify and elaborate on potential safety concerns during clinical MR imaging.
  • To present available data clarifying the status of these safety concerns.
  • To provide a comprehensive overview of MR imaging safety.

Main Methods:

  • Review and categorization of potential safety issues in MR imaging.
  • Elaboration on eight specific areas of concern.
  • Presentation of supporting data for each identified risk.

Main Results:

  • Eight key areas of potential safety concern were identified and detailed.
  • These include static magnetic field effects (biologic, projectile), time-varying gradient fields, radio-frequency fields (power deposition), acoustic noise, superconductive system hazards (cryogens, quenches), psychological impacts (claustrophobia), and contrast agent (gadopentetate dimeglumine) effects.
  • The current understanding and data status for each concern are presented.

Conclusions:

  • A systematic review highlights critical safety considerations in MR imaging.
  • Understanding these eight areas is essential for safe clinical practice.
  • Further data and vigilance are necessary to mitigate potential risks.
