thanks for kindly words. stay safe and have a nice weekend there.

Yes please try it out 👍

Thanks. Always use the prescan normalise

Bac Nguyen with no anterior coil wouldn’t you want to turn that off?

Good question. Actually no from my experience. Because the image intensity will various from light / dark throughout the image while scrolling through your sequence.

Good question which need to be consider. In my experience I haven’t notice any sar issue regarding this on 1.5T or 3T.

@@Nguyen_MRI will try it asap! 👍

Give it a try

thanks for watching. well honestly you can use the fix or ref for local areas such as knee imaging.

Good question Luca. All these axial tests were done with grappa pat 2.

That’s correct. Many people use this approach of yours.

No thing would happend beside small movement of the table and re shimming. In other words you loose overall examination time.

Thanks. Do you use multi stack in transversal plane? Or one big stack?

Bac Nguyen we use one big stack for transverse plane

Ok interesting. This transversal t2 you remember what rf pulse you have on it? Fast normal or low?

Bac Nguyen if I remember correctly it is set to fast

Try to put it to normal rf pulse.

Good question. I haven’t notice any differences regarding sar.

Great,. Thanks. I will definitely try this one. 🙂

Yes let me know ☺️

The blue line is just the indicator of your iso Center within that FOV. Try to test out the function iso / fix and ref. Having in ISO you see the blue line moves within your FOV and the table inside the scanner moves along your wanted position. But having the ref or fix it doesn’t move. This iso came along with tim4G - total imaging matrix for the first version of AvantO software. Makes your positioning much easier and won’t think of scanning outside the FOV. Another test you can do is to have it on either ref or fix. Then move your FOV way up or down and then you see the yellow box turn to orange. Means you scanning way out of isocenter.

Very helpful

I believe you can turn that line on.

Sure. At the top you see VIEW - reference lines on.

@Nguyen_MRI you are awesome! Thank you so much for sharing!

Hi. Please check the tab RESOLUTION - FILTER and then check the parameter DISTORTION CORRECTION. in your specific protocol you need to either have everything off or on in your sequences. Including your localiser. Or else this can causing such a problem as you mention here. Please try out and give feedback. Thanks.

Bac Nguyen thanks, I will try it today and let you know! 😊

Bac Nguyen yes in deed, that’s what the problem was thank you Bac!

@@Nguyen_MRI that’s could be a good video for a quick tip.

Sometimes I experience the same problem, thank for bring it up❤

Thanks for comment. From my experience I only use iso and fix. I know other use ref as well. But on the newest software xa platform you only have two options. ISO and one more.

@@Nguyen_MRI Same here, we only use fixed and iso, thats why i asked if there was an advantage in some protocols, thanks for the reply!

Unfortunately not.

If I understand you correctly put all brain sequences on fix mode. Then all spine on iso mode.

Good question. Unfortunately, not.

Good question. I’m using fix for all head examinations. No problem with perfusion or spectroscopy from my experience.

Thanks for the clarification. 👊

Yes should work 👍

No unfortunately not. Anything specific in your mind?

No need. Depends on what you want to take image of.

Can be very confusing. Ref fix are changed on the newest software. I use fix for exams where I only need to be at one place and specific. Such as knee, brain, cardiac etc. Instead of iso where the table moves to isocenter. I find fix safer to use compared to ref, because having a combination exams of let’s say brain(fix) and spine (iso). You see by using fix and plan from there you know what you get whenever you apply the sequence. If using ref you can miss postions depends on what sequence you plan from. Just try it out on your scanner and you will see.

Good question, yes and also need to be used carefully for smaller area such as head imaging.

@@Nguyen_MRI thanks. I need to master this concept. You know where I can get more information on this specific concept? Thanks!

I haven’t found a better explanation other than the manual. Besides testing myself and tried to explain further in this video.

@@Nguyen_MRI yeah I seen the manual but like to know more haha. Thanks for your video. Stay safe!

Norway

Yes

@@Nguyen_MRI Hihi em rất thích các video của anh, tiếc quá em chỉ xem hình ảnh thoii chứ tiếng thì không hiểu hết được. Anh có thể cho em tham khảo ít tài liệu về MRI của anh được ko ạ, 😄
