Diffusion. Diffusions . The tendency of a gas or solute to pass from a point of higher pressure or concentration to a point of lower pressure or concentration and to distribute itself throughout the available space. Diffusion, especially FACILITATED DIFFUSION, is a major mechanism of BIOLOGICAL TRANSPORT. . 1.00
Thermal Diffusion. Thermodiffusion . Diffusion, Thermal . The movement of molecules from one location to another as effected by temperature changes. . 0.79
Diffusion Magnetic Resonance Imaging. Diffusion MRI . Diffusion Weighted MRI . Diffusion MRIs . MRI, Diffusion Weighted . Magnetic Resonance Imaging, Diffusion . A diagnostic technique that incorporates the measurement of molecular diffusion (such as water or metabolites) for tissue assessment by MRI. The degree of molecular movement can be measured by changes of apparent diffusion coefficient (ADC) with time, as reflected by tissue microstructure. Diffusion MRI has been used to study BRAIN ISCHEMIA and tumor response to treatment. . 0.74
Cultural Diffusion. Trans-Cultural Diffusion . Transculture . Transculturation . Transculturalism . Transculturality . Culture Diffusion . The movement of cultural traits and ideas from one society or ethnic group to another. (From: Glossary of Terms.
