Diffusion Imaging in the Rat Cervical Spinal Cord

12.2K
The goal of this protocol is to obtain high-quality diffusion weighted magnetic resonance imaging (DWI) of the rat spinal cord for noninvasive characterization of tissue microstructure. This protocol describes optimizations of the MRI sequence, radiofrequency coil, and analysis methods to enable DWI images free from...

Wideband Optical Detector of Ultrasound for Medical Imaging Applications

11.7K
Optical detection of ultrasound is impractical in many imaging scenarios because it often requires stable environmental conditions. We demonstrate an optical technique for ultrasound sensing in volatile environments with miniaturization and sensitivity levels appropriate for optoacoustic imaging in restrictive scenarios, e.g. intravascular...

Source: Zheng, W. et. al., Diffusion Tensor Magnetic Resonance Imaging in Chronic Spinal Cord Compression. J. Vis. Exp. (2019)This video demonstrates diffusion tensor imaging in assessing chronic spinal cord compression. By analyzing water diffusion patterns, fractional anisotropy, and apparent diffusion coefficient values, the findings reveal axonal damage in compressed regions. The findings provide critical insights into spinal cord pathology and structural...

Diffusion

216.4K
Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...
