Yes they are the same. interleaving is sampling the signal from every other slice so as to eliminate crosstalk. Used in the spine mostly (Lumbar). If we sample from slice 1 down to slice 11 we get cross talk / cross excitation / overlap, but if we sample interleaved we go slice 1, 3, 5, 7, 9, 11, then slice 2, 4, 6, 8, and 10.
thank you very much Dr. Burton.
As a tech who is learning MRI, it was very helpful video.
Thank you so so much. Very helpful.
Thank you Dr. Christiane. It's a very interesting lesson.
Sarah, enjoyed the lecture especially on MRI artifacts
Hi, I noticed at 4:54 you said you get the lowest amplitude in the center of k space, but the center has the highest amplitude.
Great job.
Hi, nice presentation, it's very informative. Can I ask if cross talk, cross excitation and slice overlap artifact are the same?
Those all sound the same. I either refer to it as slice overlap or interleaving.

@ 1:00:51 I guess you meant to say, you excite a slice (not an image).
