Forum Introduction Magnetic resonance diffusion imaging technology is currently the only method to measure the diffusion of water molecules in vivo. The most commonly used methods include diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI). DTI has excellent imaging effects in the central nervous system, especially in distinguishing white matter from gray matter and … Read more
Medical Imaging Students Learning together, progressing together. Diffusion refers to a microscopic, random motion of molecules caused by thermal energy, also known as Brownian motion. The different structures of human tissues lead to variations in the restrictions on the diffusion movement of water molecules in different directions. If the restricted diffusion of water molecules is … Read more
According to the severity of gastrointestinal dysfunction, gastrointestinal dysfunction (AGI) can be classified into four levels, each corresponding to different treatment measures: AGI Level I: There is a clear etiology leading to temporary partial gastrointestinal dysfunction, manifested as temporary and self-limiting, with the risk of gastrointestinal dysfunction and failure. For example: nausea and/or vomiting occurring … Read more
Forum Introduction: Common types of vascular malformations include cerebral cavernous malformations (CCM), capillary telangiectasia, developmental venous anomalies (DVA), and arteriovenous malformations (AVM). CCM is a common congenital vascular malformation of the brain and is the second most common vascular malformation in the central nervous system. Its incidence ranges from 0.16% to 0.5%, accounting for 5% … Read more
