BACK TO BASIC - INTERPOLATION

- Interpolation can be a little bit confusing, because you have people saying YES use it, and you have people saying NO don’t use it. Today, I’m going to take you to a scanning session where we going to break down these rumors of either having it ON or OFF. The difference is so obliviously, which I don’t understand why these rumors are out there at all. Join me, and let’s go.
Thanks for watching and following, hope you find this video interesting and valuable.

Didn’t know you can do the retrospective reconstruction for interpolation. Thanks always for awesome practical videos!
For real, the practice videos are extremely helpful. Interpolation was amazing!! The fine detail difference was crazy!!!!
Amazing, I always looked to this tool and thought "what that thing do?", Thank u, very much
Never used it before, and never knew the use of it, but now I'm going to keep my eye on it. Thanks man.
Give it a try 👍
Great video. Thank you. 😎
You blow my mind! Thanks! Yes, use it for making images sharper if I don"t have time for increasing matrix size
that’s what I call a fine
job 👌 keep it up bro🐱🏍
Amazing. Mind blowing.
Keep it up.
Mohamed from SUDAN.
Always using it, especially when I don't use sguere matrix
Amazing video!
So there's no drawback to using it. Awesome!
Thank you for the content Bac. Love every one of your videos.
Yes we do use interpolation when scanning
بارك الله فيك ان شاء الله 🤍
Nice video 👍 i am from Saudia Arabia
Thank you
Wow great job Bac your presentation is amazing fantastic 🙏
Thanks for kindly words.
👍👍👍
Pretty much always use interpolation in - plane; I believe GE turns out on automatically for any frequency /read matrix above 256. Never liked the look of through-plane/slice interpolation though, UNLESS the acquisition is going to do reformats. Seen a lot of protocols with slice interpolation on like a 6-7mm slice, just never looked good to my eye.
Nice. First comment
Great video. Also didn't know about the retrospective recon, very handy. Bit off topic, but could you retrospectively recon a sequence from say non fat saturated sequnce to fat saturated using this method?
No, this I don’t think it’s possible.
I think you can only recon the raw/scanned images only....if fat sat (or any other scan sequence modification) was not applied during the scan, you cannot reconstruct it
What does interpolation (2,2),(3,3) upto (6,6) means?If we increase this order do we get good image?and does it take more time if we do with (6,6).What range is enough actually?
Second comment!
OK! Thanks for your Videos! Why shouldn't I always use interpolation? What is the disadvantage? Or, for what kind of sequenzes it is not good?
From my experience I use it wherever I can.
Your video awesome thanks really but what it really means interpolation?
Good question. Please check this link for further understanding: mri-q.com/zip.html
That’s fine if interpolation 1 means it’s turned off and 2 is on.Can you please tell it for 3,4,5,6 what does they do.will be waiting for your answer
Thank you 🙏🏻
2 means it’s double. So having 256 it will be 512. 3,4,5 shouldn’t be play around with. Means you double it even more. And that just messing with everything.
Can you make video for chemical shifting artifact c spine region t1 fs sequnse, how to reduce .please can u explane sir
Thanks for comment. There is no chemical shift artefact on fatsat sequences because you already suppressed the fat. Please read more here: mriquestions.com/chemical-shift-artifact.html
Hi,
How can I see the reconstructed images on the viewing mode after creating? I can’t open it :(
Should be in the browser like the rest of the other sequences.
Thanks for your help! :) another question? Is there any possibility to retrieve deleted images in siemens scanner?
I see you using “copy image position” what does it do . Thank you
It’s more like copying the image where you at. So you don’t have reposition etc. Doing this the new plan of yours will align at same position as the one you position. Please try it out and you will understand more of it. I use it all the time for planning. Being able to work faster and more efficient.
@@Nguyen_MRI will certainly do try it. Thank you so much for a quick response. Please keep going nothing is simple or difficult in MRI all important. Always looking forward to seeing your videos
@@abrabr6720 awesome. Yes it’s try and fail all the time. Nothing is more important to share the knowledge in the community. More videos will come. Stay tuned 👍
@@Nguyen_MRI looking forward
Please dear k space
What's trade- off use to be interpolation?
None
Any disadvantages of using interpolation
From experience no. But I’m going to do further testing after great comments here which made me curious. Stay tune
Plz new protocol
?
In need lower limb angio of protocol
can you share to me some books about parameter mri ( pdf) ¿
I don’t have any pdf of books. I recommend you to invest in this one for further understanding : www.amazon.co.uk/Handbook-MRI-Technique-Catherine-Westbrook/dp/1118661621/ref=mp_s_a_1_3?dchild=1&keywords=catherine+westbrook+mri&qid=1600528042&sr=8-3
How we minimize time in DWI sequence in spine plz make video
Then why have it off ever
Good question. One thing is to save space. Having it on the file is larger. BUT that shouldn’t be the main reason. To your answer: I don’t know why it is off from the siemens tree. But you can clearly see the impact off that by having it on.
