Diffusion tremor imaging (DTI) is a non-invasive imaging technique for visualization of white matter fiber tracts. The protocols to use it for imaging brain are well established, but its efficacy and potential applications in the spinal cord imaging are poorly understood. This article gives an overview of using DTI for spinal cord pathology imaging. DTI is capable of measuring direction and magnitude of diffusion of water molecules in tissues. Magnetic resonance imaging (MRI) has been the gold standard in imaging soft tissues.
However, DTI provides additional insights into tissue characteristics hence has a great advantage in the diagnosis of various neurological conditions. DTI is essentially a MRI-based technique which can measure location, orientation, and anisotropy of brain’s white matter tracts. The technique is both qualitative as well as quantitative. In brief, during DTI…
