1. 1. High-resolution diffusion-weighted brain MRI under motion

   Författare :Mathias Engström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Magnetic resonance imaging is one of the fastest developing medical imaging techniques. It provides excellent soft tissue contrast and has been a leading tool for neuroradiology and neuroscience research over the last decades. One of the possible MR imaging contrasts is the ability to visualize diffusion processes. LÄS MER
