Supine with hands down. Although this isn’t scan performed often in my Trust. But I found it really interesting I could use two ultra flex coils for coverage. But of course challenging when dealing with a bigger BMI. But this was very educational. Thanks Bac!
I use superman positioning, with body 18 and table coils. This mainly beacause we only have avanto with 60 cm gantry opening ( it can be a problem for most pasient to get the forarm close to the isosenter and you will end up with bad images and unnecessarily problems). With short scantimes, this is 9/10 not an issue for the pasient. Ofc if the pasient suffer from shoulder pain, we always try other posistions like head first supine). And as alway, good video! 👍👍
i would do it like a superman position and i always feel bad for the patient knowing its very uncomfortable. other positions not possible for me since the scanning bore size is to small.
Hai bro which siemens software is shown in your video can you just do a video on the software you using in this video which will help for tech who see that for first time Plz replay thankyou
Sir I have a question about mri. A T1 SE scan is made with the following settings: TR 500ms, TE 20ms, matrix 192, FOV 256, NSA(NEX) 5, scan time 8 minutes. The lab technician is dissatisfied with the scan because the time is much too long. He wants to improve this, and negatively affect the other image quality and properties as little as possible. Reason which parameter (FOV, matrix, TR, TE, NSA, slice thickness, flip angle) you would adjust for this and which value you would choose for this. Only one parameter may be modified. Should I change the NSA(NEX)?
Changing the nex will affect the scantime and snr. There is no such as only changing one parameter to obtain good images. Have you tried to use the sequence from the vendor?
@@ehimwenmaj3438 ok. In this assignment nex seems a bit high. Maybe lower this but again depends on what coil you have if there is enough snr to lower. I guess it because you have a matrix of only 192 out of fov 256. Which is not a proper resolution. 256/192= 1.3mm voxels size. So many other factors as well which affect each other.
I use the neutral position, forearm, elbow, arm by the side in the true anatomical position. I move the patient towards the unaffected side to ensure the part being scanned is close enough to the isocentre. If it's the forearm or elbow that I'm scanning, I use foam pads, immobilisation pads to raise it up a little _ this aids in getting the FOV within Isocentre. In scanning the arm, I don't need this maneuver.
Good evening sir i am from India at up in Rampur .i am big fan of you .will u please share your number to me for any query if needed to me the way of learning is effective . Keep going.

I am from Sudan and i learning MRI from your videos
Thank you Brother 💐💐💐
I wrap the body coil , never would I use 2 coils as my MRI is old , burn , but your new system amazing I would go for it 🙏 tremendous job Bac
nice video, thank you
بارك الله فيك ان شاء الله 🤍

Thank you !!!! Very greatly appreciated all your tutorial. Would you mind to go over how to set up a new protocol. Thank you
great

First to like and comment
hey man, i had this mri, i need some arm mri to compare, if you could look at it would be so great
I do it like as the 1st option but in prone
super man position or in a side with body coil long side
👍🏻
Please sir please send me parameters guide Siemens 1.5 magnetom avanto
i would do it like a superman position and i always feel bad for the patient knowing its very uncomfortable. other positions not possible for me since the scanning bore size is to small.
It’s not a patient friendly exam. :(
How did you label patient orientation for this specific Superman position?
Prone head first.
Thank you 🫡
Hai bro which siemens software is shown in your video can you just do a video on the software you using in this video which will help for tech who see that for first time
Plz replay thankyou
Xa50 software.
@@Nguyen_MRI thanks bro and can you do an outline video the this software if possible

@@Nguyen_MRI It’s just an assignment from school. I know that practically you can't change just one parameter but i don’t understand this

As for the coil, I use the Body coil and I wrap it around the patient's limb for investigation.
@@collinsm.2168 awesome thanks for sharing your approach. 👍
@@Nguyen_MRI thank you
How do you perform MRI forearm?
Like an elbow, superman-pos. with table coils and large flex along the arm.
i‘m a bit surprised that a prone positioning is not shown as an option. it’s basically the same positioning as hand/wrist exams
Yes almost like the first example I had. Could also do that.
