Diffusion Tensor Imaging

Diffusion Tensor Imaging (DTI) is a type of magnetic resonance imaging (MRI) that is commonly used in the field of neuroscience to map the white matter pathways in the brain. Unlike conventional MRI, DTI is able to measure the movement of water molecules within the brain and establish the direction and integrity of the neural connections throughout the brain. DTI has become an essential tool for assessing connectivity in the human brain, enabling researchers to study the effects of brain disease and injury on neural connections. In particular, DTI has been useful in the study of neurological disorders such as Alzheimer’s and Parkinson’s disease, where changes in white matter connectivity have been observed. The technique has also been useful in neurological therapy, allowing clinicians to identify the location of damaged neural pathways and to monitor the effectiveness of treatments such as deep brain stimulation or stem cell therapy. In order to obtain high-quality DTI data, patients must lie completely still while the images are being acquired, and the images must be processed using complex algorithms to extract the directional information of the water molecules. Despite these challenges, DTI has become an increasingly popular research technique in neurology, and is poised to continue making significant contributions to the field in the coming years.
