Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

9.2K
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: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,...

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Motion Of A Charged Particle In A Magnetic Field01:22

Motion Of A Charged Particle In A Magnetic Field

6.8K
A charged particle experiences a force when moving through a magnetic field. Consider the field to be uniform and the charged particle to move perpendicular to it. If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of motion, a charged particle follows a curved path. The particle continues to follow this curved path until it forms a complete circle. Another way to look at this is that the...

Atomic Nuclei: Magnetic Resonance

1.2K
The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

Nuclear Magnetic Resonance (NMR): Overview

6.8K
Nuclear magnetic resonance (NMR) is a phenomenon exhibited by certain nuclei that can absorb characteristic radio frequency radiation under certain conditions. NMR has been extensively applied in molecular spectroscopy and medical diagnostic imaging. In both these applications, the molecule or subject under study is placed in a magnetic field and irradiated with radio frequency energy.
NMR spectroscopy generates a spectrum where the characteristic absorption frequencies of the sample are...

Summary

Providing tactile feedback, such as medical tape on the forehead, significantly reduces head motion during magnetic resonance imaging (MRI) scans. This simple method improves image quality by minimizing motion artifacts, especially for individuals prone to excessive movement.

Area of Science:

  • Neuroimaging
  • Medical Physics
  • Cognitive Neuroscience

Background:

  • Head motion is a significant source of artifacts in magnetic resonance imaging (MRI), compromising image quality in both clinical and research settings.
  • Subjects are often unaware of their head movements during MRI scans, hindering self-correction.
  • Reducing head motion is crucial for accurate diagnostic interpretation and reliable experimental results in MRI.

Purpose of the Study:

  • To investigate the efficacy of tactile feedback as a simple intervention to reduce head motion during MRI.
  • To determine if tactile feedback can improve image quality by minimizing motion-induced artifacts.
  • To assess the relationship between baseline head motion and the effectiveness of tactile feedback.

Main Methods:

  • Twenty-four participants underwent MRI scans while performing three cognitive tasks (passive viewing, mental imagery, speeded responses).
  • Two conditions were compared: with medical tape applied to the forehead for tactile feedback, and without tape.
  • Translational and rotational head motion were quantified and compared between the two conditions.

Main Results:

  • Application of medical tape to the forehead significantly reduced both translational and rotational head motion during MRI scans.
  • The effectiveness of tactile feedback in reducing motion was consistent across different cognitive tasks.
  • A negative quadratic relationship was observed: individuals with higher baseline head motion experienced greater motion reduction with feedback.

Conclusions:

  • Tactile feedback using medical tape is a simple, cost-effective method to decrease head motion in MRI.
  • This technique can enhance MRI image quality, particularly in scenarios where significant head motion is anticipated.
  • The findings suggest a practical approach to improve data acquisition in various MRI applications.
