Diffusion Weighted Imaging (DWI) in Neuroradiology... made easy!

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. 0:00 - Introduction 01:04 - What is diffusion? 09:55 - Basics of diffusion weighted imaging 10:17 - The Basics of MRI 21:08 - The basics of DWI 30:08 - b0-DWI, b1000-DWI and ADC-map 37:07 - The TRACE-map 41:00- True diffusion restriction versus T2-shine through 44:48 - Why is an ischemic stroke diffusion restrictive? 48:58 - Applications in Neuroradiology 49:11 - Diffusion restriction in brain abscess and epidermoid cysts 55:59 - What is T2-black out? 57:42 - Diffusion restriction in brain tumors 1:03:17 - What is T2-wash out? 1:05:44 - Summary and Key Messages This video is brought to you by the neuroradiologist:   / theneuroradguy     / the_neurora.  . https://theneuroradiologist.org/ #radiology #neuroradiology #neurology #medicalstudent #neuroradiologist #theneuroradiologist #MRI #medical # #neurosurgery #diffusion #mri #radiologytechnologist #radiologyresident
