MRI - MATRIX BACK TO BASIC
Рет қаралды 11,122
Жыл бұрынIt’s been a while since I had a topic like this. Matrix is an important parameter when it comes to optimizing a sequence. I hope with this video you’re able to have a better practical understanding of matrix.

Matrix. Is this something you have in mind whenever you optimize a sequence?
@aagoela Жыл бұрын
Definitely- would appreciate your thoughts on interpolation. I assume that’s why your video shows different resolution values for “acquisition” and “reconstruction”?

Thankyou for your videos 🙏 very informative Uhm quick question does it apply as well if you are scanning a small FOV part like an elbow? Should I decrease the Base resolution?
@Nguyen_MRI 3 ай бұрын
Yes this is the basic of resolution.
@fakenamefakesurname5005 Жыл бұрын
Thank you for this video, so if i want to make the FOV bigger i also need to increase the base resolution in order to maintain the resolution

with the same pixels , what is your perception between higher or lower fov compared to the image quality?
@Nguyen_MRI Жыл бұрын
From my opinion I want dedicated fov for area of interest.

Hi Bac! Great video as usual! I just want to focus on the first comparison.. In my opinion the second scan is far away better due to the higher SNR (1,36). When you zoom in, it seems that the second scan has much less noise. So the question is, don't you think that is much better increase the FOV and the base resolution to minimize noise instead of having a tighter FOV and less base resolution? I mean, if the acquisition matrix is the same, might as well have an image with less noise, right? (obviously without considering the increasing of the time of acquisition)
@Nguyen_MRI Жыл бұрын
Yes but it all depends on coils and radiologist preferences. Imaging dedicated organs from my experience they don’t want big fov even though the resolution is the same. Also for pediatric imaging. I made this video just for a better understanding of the relationship between matrix and fov. Of course all pro and cons but the theory and practice are there.

the resolution is the same, but in your opinion which is the best image without taking into account the fov?

Thanks for tuning in on my channel. I don’t think your hearing is bad. Probably my English also not an easy topic. Nevertheless, many great books out there to read for a better understanding. It’s for sure a knee which I demonstrated in this video.
