Summary:
Summary:
MRI is a widely used medical imaging technique in both clinical and research settings.
In neuroimaging, MRI captures detailed images of the brain for diagnosis and study.
Think a picture of the brain at a certain point in time.
Using VR to handle MRI data enhances visualization through an immersive 3D experience compared to traditional 2D methods.
Augmented Reality applications in MRI neuroimaging remain largely unexplored.
Introduction
Introduction
MRI
MRI
MRI is a short form for Magnetic Resonance Imaging, a method using which internal organs are imaged via strong magnetic fields and radio waves. This is useful detect clots, blockages or other forms of disturbances or deformations in the human body. An MRI scan shows a detailed and color report about body organs in the picture and according to which further medical procedures or surgeries are carried out.
In Neuroimaging
In Neuroimaging
MRI is widely used to visualize the structure and function of the brain and nervous system. It helps detect abnormalities such as tumors, strokes, multiple sclerosis, and neurodegenerative diseases like Alzheimer’s and Parkinson’s. Advanced MRI techniques, including functional MRI (fMRI) and diffusion tensor imaging (DTI), allow researchers and clinicians to study brain activity, connectivity, and white matter pathways in detail.

VR and MRI for Neuroimaging
With the integration of Virtual Reality, MRI neuroimaging is becoming more immersive and interactive. VR allows users to explore and manipulate 3D brain scans in a spatial environment, enhancing medical education, diagnosis, and surgical planning. This innovation helps neurologists, radiologists, and surgeons better understand complex brain structures and plan interventions with higher precision. VR-based MRI visualization is also being used in research to study brain function in real-time and improve patient engagement by making medical imaging more accessible and intuitive
