Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

5.2K
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...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

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...

Summary
This summary is machine-generated.

Healthy subjects adapt to repeated ultra-high field (UHF) 7 Tesla (T) magnetic resonance (MR) scans, experiencing fewer short-term effects like dizziness and nausea over time. Motion and peripheral nerve stimulation remained unaffected by multiple UHF MR exposures.

Area of Science:

  • Neuroimaging
  • Medical Physics

Background:

  • Ultra-high field (UHF) magnetic resonance (MR) imaging, particularly at 7 Tesla (T), offers advanced diagnostic capabilities.
  • While generally well-tolerated, UHF MR can induce transient side effects such as dizziness and nausea.
  • Limited data exists on the cumulative effects of multiple UHF MR exposures.

Purpose of the Study:

  • To investigate the subjective experience of short-term effects in healthy individuals undergoing repeated weekly 7T MR examinations.
  • To assess the occurrence and changes in motion artifacts during multiple functional MRI (fMRI) sessions at 7T.
  • To evaluate subject adaptation and comfort levels across seven consecutive 7T MR examinations.

Main Methods:

  • Utilized a questionnaire to collect data on short-term effects experienced by participants.
  • Conducted seven weekly 7T MR examinations for each participant in a motor skill fMRI study.
  • Analyzed changes in reported symptoms and quantified motion in fMRI images using statistical models.

Main Results:

  • A total of 360 questionnaires were completed by 67 participants across one to seven examinations.
  • Significant decreases in dizziness, inconsistent movement, nausea, and headache were observed with increasing examination numbers (p<0.03).
  • No significant impact of repeated exposures on peripheral nerve stimulation or subject motion was detected; overall examination experience improved significantly (p<0.001).

Conclusions:

  • Healthy subjects demonstrate adaptation to the strong static magnetic field during multiple 7T MR examinations.
  • Subjective short-term effects, including dizziness, nausea, and headache, diminish with continued exposure, correlating with increased participant comfort.
  • Repeated 7T fMRI sessions do not lead to significant changes in subject motion, suggesting stability in imaging quality over time.
