Magnetic Resonance Imaging

Magnetic Resonance Imaging

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...

Motor Unit Stimulation

Motor Unit Stimulation

When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Area of Science:

Magnetic Resonance Imaging (MRI)
Muscle Physiology
Biomedical Engineering

Context:

Conventional muscle functional MRI (mfMRI) has limitations in visualizing deep muscle activity, particularly in the trunk.
Accurate assessment of muscle activation is crucial for understanding biomechanics and diagnosing neuromuscular conditions.

Purpose:

To develop and validate a fast-acquired muscle functional magnetic resonance imaging (fast-mfMRI) technique.
To fuse anatomical and functional MR images for enhanced visualization of muscle activity.
To assess the feasibility of fast-mfMRI for capturing muscle activation during exercise.

Summary:

Fast-mfMRI combines TrueFISP anatomical images with spin-echo echo-planar imaging (SE-EPI) functional images.
MR images were acquired from healthy males at rest and after plantar flexion exercise.
Muscle activity areas were identified by adapting resting thresholds to post-exercise functional images, creating fused images with rich anatomical detail.

Impact:

Fast-mfMRI images can be acquired in just 14 seconds, significantly reducing scan time.
This technique demonstrates potential for effective muscle activity measurement in challenging areas like the trunk.
Fast-mfMRI may offer a valuable tool for clinical and research applications in musculoskeletal imaging.
