You're in luck! It's the very first topic in this video: ruclips.net/video/S5MGXfL9tro/видео.html To directly answer your question, MRI is fantastic at detecting cholesteatoma (both primary and recurrent) and differentiating it from inflammatory debris. Non-echo-planar DWI has superior sensitivity compared to echo-planar DWI, especially for lesions under 5mm.
@@ENT_Imaging Hi Barton, I would have to admit that this is the first video that I viewed from your channel, and I'll take time to review others. What I particularly liked about this video is how you explained in a fool-proof format. I also liked that you explained the equation clearly, citing an example to assert your explanation. The video is also relatively short, which is a major plus.
You might like "Quick Cases", which are designed to be about a minute long. I'll be making more of those once the main lecture series is complete. The physics videos (like this one) are brief, but there are only a few of them. The head and neck lectures are of course longer, but I don't waste time asking you to subscribe or telling cute cat stories or whatever. It's designed to be compact information.
That's a good question! You can't just assume that everything on the b0 image is automatically wrong. In this video, the artifact is familiar because of the shape (it's an echo of the globe) and position. Also, it would be quite a coincidence if the T2 effects seen in a b0 image were perfectly balanced by the diffusion effects in the b1000 image.
Maybe. Although I am trained in Neuroradiology, my passion is head and neck imaging. There will be some basic neuro here and there, but most of the content will be H&N (at least in the near future).
ADC = Apparent Diffusion Coefficient. ADC is the actual diffusability of water molecules in the environment. Unfortunately, we cannot measure ADC directly, so we need to use diffusion-weighted images and then make mathematical corrections, as explained in the video.
Great Content! Thank you very much from an ENT Resident.
Could we please get a video on Cholesteatoma imaging specifically MRI and different DWIs?

Great explanation. Thank you.
Love this! More videos like this one please!
Okay, but please be more specific. What aspects of this video make it superior to the other videos on the channel?

You gave me a response for an enigma ! thank you .
Thanks!
Hi!! I have a question !Why an abnormality in the b=o DW Image is an artifact and not a high diffusion region?
That's a good question! You can't just assume that everything on the b0 image is automatically wrong. In this video, the artifact is familiar because of the shape (it's an echo of the globe) and position. Also, it would be quite a coincidence if the T2 effects seen in a b0 image were perfectly balanced by the diffusion effects in the b1000 image.
@@ENT_Imaging thank you so much!!!
Brilliant sir thanks 🙏
Great video, thanks!
Nice vid! I would love to see neurology cases on your channel
Maybe. Although I am trained in Neuroradiology, my passion is head and neck imaging. There will be some basic neuro here and there, but most of the content will be H&N (at least in the near future).
Why does the artefact didn’t show up at higher DWI?
Great question. Perhaps the patient moved slightly on the b0 images, but remained still on the b1000 images.
What is ADC?
ADC = Apparent Diffusion Coefficient. ADC is the actual diffusability of water molecules in the environment. Unfortunately, we cannot measure ADC directly, so we need to use diffusion-weighted images and then make mathematical corrections, as explained in the video.
