Summary: A fresh study compared two advanced imaging techniques, dMRI-based tractography and PS-OCT, to chart muscle fibers positions in the human brain. These findings suggest that combining these methods could improve our understanding of brain porosity, which could aid in the early recognition of degenerative diseases.
dMRI offers strong muscle scanning, while PS-OCT provides high-resolution information, making them complement tools. This study might help to make neurological situations more easily diagnosed and managed.
Important Information:
- To map muscle particles in the human brain, dMRI and PS-OCT were used.
- Combining these methods might be able to find subtle changes in the brain’s microstructure.
- The objective is to create early detection techniques for neurological conditions.

Researchers used two superior imaging techniques, diffusion magnetic resonance imaging (dMRI)-based tractography and magnetization sensitive optical coherence tomography ( PS-OCT), to compare the positions of nerve fibers in a human brain in a new study.
The findings may help in combining these methods, each with its own advantages, to advance our understanding of the body’s morphology and provide new methods for identifying different mental disorders first.
Isabella , Aguilera-Cuenca , from the University of Arizona will present this research at Frontiers in Optics + Laser Science ( FiO LS), which will be held 23 – 26 September 2024 at the Colorado Convention Center in Denver.
As populations get longer and people get older, degenerative diseases are getting more prevalent. Better understanding the connection between mental morphology and these diseases may lead to the development of better methods for avoidance, detection, and administration, said Aguilera-Cuenca.
Due to its impact on brain connection and communication pathways, muscle fiber orientation is a crucial component of brain microstructure. Using dMRI, a non-invasive method of imaging that uses water protein diffusion to reveal fundamental connectivity, is one way to research this microstructure.
DTI, a highly specific form of dMRI, can be used to recreate muscle fibers pathways through a technique known as tractography. Although DTI is sensitive to differences across brain tissue environments, it ca n’t detect specific cellular changes and can only resolve nerve tracts, not individual axon orientations.
PS-OCT is likewise useful for studying head morphology. It uses the qualities of back-scattered light and deviations in fragmentation to produce depth-resolved cross-sectional images of muscle microstructures.
This data can be used to differentiate between white and gray matter and discover fibre tracts with micrometer-scale resolution. But, in scattering media such as brain cells, PS-OCT can just picture up to a few centimeters full.
The researchers used both techniques to photograph a mortal brain specimen that had been fixed in paraformaldehyde and then stored in PBS with sodium loads in order to compare quantitatively the distribution of muscle fibers orientation with dMRI-based tractography and PS-OCT.
Similar to what was discovered by dMRI, the results demonstrated that the polarization properties of stage retardation and the optical plane can be used to map brain fiber presence and orientation in brain tissue.
This indicates that PS-OCT has a strong chance of validating dMRI information, which will help researchers learn important information about how muscle fibers ‘ microstructures are organized, which is essential for understanding how neurodegenerative conditions change and how regular physiology might change.
Aguilera-Cuenca stated that in order to improve this work, we will examine the histological changes in a range of mind regions in patients with various neurological conditions in order to identify changes that occur with the onset of disease.
We hope that the findings of this study will lead to novel methods for early identification of these diseases.
