- This week’s video we’re going to scan a shoulder using a 4ch flex coil, where I will share some tips and tricks for fat suppression improvements.
Thanks for watching and following, hope you find this video interesting and valuable.

Nice job! Thank a lot!
Thank you so much! This is really a big help
Thank you for the video, great Quality images👍 keep it up bro😉
Thank you so much pro
Thank you
Good work
Thank you
Thanks for the video Bac. I had never used the perpendicular option like this. I love it! I love your thoughts on the one plane localizers too. Great information.
I did not know about this feature. Thank you
Very impressive
Thank bac brother 🙏
Great sir,👌
Great explanations for planning & how to make homogenous images for off centre imaging. Learn a lot but sadly I don’t have Siemens systems 😀😀
Helpful ✌️✌️✌️
I appreciate this video about how you set up your localizers individually. This is helpful because I understand that it is very confusing when you don't have good localizers due to rotation.. I struggled with the shoulder MRI on the ICU patient I will try this method next thank you so much!
Thanks for kindly comments. Wish you the best with the test. ☺️
I like the workflow set up you use. My protocols are set up to take a 3 plane localizer at once and I hate it for shoulders because they are never accurate and I have to repeat. I feel like this should be a simple protocol but turns into a long scan if it’s not set up properly.
Very true. Localisers are so essential for being precisely and fast.
Thanks Bac you are my MRI superhero! How about some more tips and tricks on doing MSK without dedicated coils and also on brachial and lumbar plexus scans 😉🙏
🥰 thanks.
Please make a video of Functional MRI technique and post processing
Hi sir plz can u do native renal mra without trigger on siemens eara thanks
Didn't know about it before. Thanks Bac
I will sure try it out this week.
Bac, could you pls do a video on Upper Limb position and scanning? 🙏
Nice. Keep me updated 👍
@@Nguyen_MRI I will
Thanks.
👍
Sir I am very glad to attend the class ❤ very good information thank you for your information ❤
Thank you for kindly words. Keep up the good work and learning ☺️
@@Nguyen_MRI thanks sir kindly make video on MRCP(tricks)

Great videos! Why do you leave the spine coil on together with the Small Flex coil ? I thought that would give more noise in the images ?
Great notice. It should be off indeed. Mistaken from me when I created this video.
Hi Bac, thanks for the video, would you use similar positioning and flex coil for bicep imaging?
Depends on how big the area of interest is. This coil doesn’t cover much
@@Nguyen_MRI normally these patients are body builders, so big arms, could we wrap a body coil around the bicep the way you did with the flex/shoulder. Or is it better to just use a larger flex coil.
I think it would be better to use spine 32ch combined with body 18 if having so. No wrap to cover a larger area. Place the patient all the way to the other side. Of course use cushions and protect against getting burned.
@@hopsie9983 For biceps muscle (not insertion), use the body coil lengthwise like you do for long bones. Phase is A>P for AX & Sag; S>I with 100% OS for Cor.
If I am mistaken, any correction & suggestion is appreciated,🙏.
Nice video and everything, but ain't nobody got time for that in the real busy hospital i work. Rads will read anything. 😉 😜 😜 😜
Thanks. If you don’t have a dedicated shoulder coil. How would you setup this exam then?
Why restore pulse on your pd fs tra? TR 2600? Thought that would be long enough for pd
Will achieve a more pdw using that. Try with the same tr with and without. You will see the difference using restore pulse.
Sir gud morning .

You don’t use FH as phase direction in SAG & COR . Can you give us the reason?
No specific reason actually. mrimaster.com/PLAN%20SHOULDER.html
Phase oversampling is set at 100%, in this case you could lower that, but the SNR will go down. But I don’t really understand if the image quality will decrease? Does phase oversampling increase image quality because of higher SNR?
Good question. Snr or in this case phase oversampling will have a final impact on the image quality. If having low snr on a sequence you will get noise images, thereby mediocre or bad “image quality”
Thanks for ur helping us.I see when u planning SJ spine coils on.is it ok with flex coil?
It should be of from my opinion. I try to have only flex on. Must be forgotten from me due to auto coil. Thanks.
Ok Bac thanks for replying me. l am from Sri lanka .can u Send ur WhatsApp number
Im not using whats app unfortunately.

Bac hi✋ help me pls, how (correct) reduce "fs" artefact flex coil from big patients? Sorry for my English, I'm from Russia)
Hi Bac...
Axial plane : cutting direction from top to bottom. How to edit ? Please..

thanks ..
So you can’t use this step for regular shoulder coil right
Sure you can. If having suboptimal fat suppression.
Why do we use fat sat (weak) for msk studies.
Good question. This all depends on what your radiologists want and prefer. Some want totally fat suppression (strong) but some prefer weak which doesn’t suppress all fat.
Thank you
@@Nguyen_MRIDo you think it is possible that in the latest software (MR XA51) the Weak and Strong options both with FatSat and SPAIR are not configured correctly? In our site, even with the weak option, the bone is as black as soot. 😮
When you use a shoulder coil does it limit the field of view that a radiologist sees? Because I am curious that the 4 channel flex coil can also successfully expand field of view.
It will cover somehow same as a shoulder coil. You’re also able to use the larger flex if having so. I wouldn’t use this coil if I had dedicated shoulder coil. A dedicated coil is faster to setup and of course being able to get better images. This approach is for sites which doesn’t have a dedicated coil. If want to see beyond the shoulder, another coil must be used.
@@Nguyen_MRI Thanks. I think I asked the question wrong so I edited it. So if I understand better now, the 4 channel flex coil will cover same area as shoulder coil. But can also cover more field of view than the shoulder because it is larger.
However the drawback is less clear images(in resolution) than the shoulder coil?
@@Nguyen_MRI have you ever heard of a radiologist complain about not using a shoulder coil or heard from those centers that didn't have it?
@@HeyIntegrity no I haven’t. And I have been on private practice without dedicated coils and university hospital with dedicated coils. If want to see beyond what the coil can cover, then we just need to improvise and try to solve the case somehow.
@@HeyIntegrity if having the possibilities then use dedicated coil which is easier to create homogeneous images and of course better within shorter time. More channels compare to 4ch flex. This flex is good to use if not having anything else available. I will definitely choose dedicated if possible. It not, then just need to tailor and improvise.
Bac nói tiếng Việt được không ạ
Just a little. Thanks.
Anh người Việt phải ko anh...???
Yes.
@@Nguyen_MRI hay quá, a có làm mri với máy Philips ko anh Bac????
Unfortunately, I only work with siemens.
