2D / 3D MRI for brain tumors diagnosis
Hello

I am a research master student, my thesis on artificial intelligence and MRI in the process of diagnosing brain tumors, the objective is to determine the type of tumor in the image.

I have not found the advantages of using a 2D image in the diagnostic process instead of 3D images, since the 3D image is richer and can be copied into two dimensional slices as well.

What role does the 2D image play in the tumor diagnostic process ?

Siemens Skyra 3 T
In MR cardio exams I perform a sequence called trufi-frequencyScout-multi.

This sequence provides several images (from a same slice) each one with a specific frequency.
After this, we choose the better image and use its frequency value as an entry in the cine subsequent sequences.

The question is: Where do I find the place to insert this Value in the Cine sequence?
I travelled all the cine sequence away and could not find.
Anyone can help?

Thanks a lot.

k space explanation
dear all,
I am trying to get a feel for what k-space is. So far I have not got an explanation that I understand. My idea to picture the frequencies that get emmitted from a slice as follows: - We have a box filled with still waterrn - a set of objects get dropped into the water simultaneously - every object emmits waves that are specific to its shape. To fill k space, what is measured and how? All I know is that the sampling frequency stays the same. Sorry for the ugly formatting. Did not find help on that. Thanks Martin
