Since we used Body Coil and Spine coil for lumbar MRI at the same time. I presumed it gives more signal. Could we used PAT techniques to reduce time? Does it make a lot difference with the SNR?

Hi Bac! In my work experience, in lumbar studies I only use posterior spine coils. To avoid the loss of signal, I select prescan normalize with broad range mode on. I've noticed the difference between this choice rather than normale mode selected. I'm curious to know what you think about that. Let me know 🤗

another question. When doing total spines. When you get that error that the scan won't run (because you are scanning different areas of the spine) how do you fix this? I ran into this last week with a pt that I was doing a Brain/pelvis w/wo. Didn't want to reloc because I wanted my settings saved. The scanner absolutely did not want to run a Coronal T2 on the pelvis. It's been so long since I had this issue I forgot how to resolve it.

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

Hi, Bac. Thanks for sharing. You told that in axial plane for the Lspine, we can use AP or RL phase enc, with or without presat, depending on the activation of anterior coil channel. Is it possible to apply parallel imaging with both of phase encoding combinations or only for one of these?

Very informative thank you for your videos ! Question. When using both spine coil and body 18 coil in the AP phase direction do you ever worry about cross talk artifact? I’ve noticed If I have a coil set up for a pelvis and I’m using a spine coil for lumbar. If I don’t turn off the body 18 coil I will get artifact. Is this because the coil is outside of FOV?

Good video as usual. For the portion about using anterior coils for lumbar spine. I’m interested to know what filter settings you used, Pre-Scan Normalize, Normalize, or no filter? If you do not use an anterior coil and have one of the filters on the images can look very similar to the ones you shared that have lower signal intensity.

@Nguyen_MRI

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.

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.

@Nguyen_MRI
Жыл бұрын
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.
