I gave this lecture at Boston Children's Hospital. This lecture describes the types of artifacts seen in magnetic resonance imaging (MRI) with an introduction to 3D imaging.

thank you very much Dr. Burton. As a tech who is learning MRI, it was very helpful video.

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.

Hi, nice presentation, it's very informative. Can I ask if cross talk, cross excitation and slice overlap artifact are the same?

@christianesarahburton5456 3 года назад

Those all sound the same. I either refer to it as slice overlap or interleaving.

@TC-dw6wg 2 года назад

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.
