Показать описание
Diffusion weighted imaging made easy! Diffusion weighted imaging (DWI) is one of the most important sequences in Neuroradiology. It's hard to imagine imaging of acute ischemic stroke without DWI, and it's role in differential diagnosis of brain tumors for instance can't be underestimated. It's also a difficult sequence to understand. In this video we explore the physical basis of the DWI sequence, we learn how to correctly analyze a DWI-sequence and illustrate the DWI-technique with lots of examples from daily neuroradiological practice.

Sir can you tell some coditions where we can seen T2 washout

If lesion is hyperintense on DWI but isointense on ADC, would it consider as restricted diffusion?
