|February 28, 2020
Summary
Magnetic resonance (MR) technologists frequently report symptoms like dizziness from static magnetic field (SMF) exposure. New symptoms, including radiculopathy, were identified, highlighting potential occupational hazards in MR imaging.
Area of Science:
- Occupational health in medical imaging.
- Biophysics of magnetic resonance imaging.
Background:
- Magnetic resonance (MR) imaging utilizes powerful static magnetic fields (SMFs).
- Technologists operating MR scanners are potentially exposed to these SMFs.
- Understanding the health effects of SMF exposure is crucial for technologist safety.
Purpose of the Study:
- To investigate the symptoms experienced by MR imaging technologists due to SMF exposure.
- To identify previously unreported symptoms associated with SMF exposure in MR environments.
Main Methods:
- An investigator-designed questionnaire was distributed to MR imaging technologists via a Facebook safety group.
- Data collected included demographics, symptoms related to SMF exposure, and educational background.
- Descriptive statistics, t tests, and thematic analysis were employed.
Main Results:
- 408 technologists participated, with 78% reporting undesirable symptoms from SMF exposure.
- Common symptoms included dizziness, vertigo, visual disturbances, nystagmus, and metallic taste.
- Dizziness severity correlated with higher magnetic field strengths.
Conclusions:
- Dizziness remains the most reported symptom, consistent with prior research.
- New symptoms such as radiculopathy and dropping objects were identified.
- Educational pathways for MR technologists are inconsistent across different settings.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

01:23Atomic Nuclei: Nuclear Relaxation Processes
1.2K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis.
