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

Toshiba Vantage Titan 3T
While planning vertebral discs for axial cuts is there any way to align the slices perpendicularly on coronal plane? Currently I have to manually align them on the vertebral column which is tedious and sometimes erroneous.

I have worked on Siemens Avanto and there is option to select the slice to align perpendicular so that I only have to pay attention to one plane while in Toshiba the task is a bit more complicated. Though there is an option of aligning all slices perpendicularly but it does not work or may be I am doing something wrong.

Brain MRI Help
Can someone please help me interpret this horizontal MRI T2 slice? The images are of just behind my eyes. I don't think those black dots are meant to be there... I know that foramen make a black dot but I don't think that there are any foramen where the dots are.

Artifact in Abdomen LAVA
This artifact appears on every slice of an abdomen LAVA scan, and it looks like puzzle pieces. The artifact was gone in a re-scan using similar parameters. Does any one has an idea what might have caused it? Thanks.

I think it's better to plan both ureters, put the pack of slices exactly coronal on an axial abdomen slice including both kidneys, take care on a sagital slice to give an angle parallel to spine but including the bladder and the space behind it, use foldover direction (siemens) or Rfov 1 (GE), fov 400-450, sl thick 0.80-1mm, open the 3d slice pack as much as needed, use navigator-pace (siemens) or triggering (GE).

A preparation of diet is needed some times, additional sequences (haste, fiesta, vibe+iv or lava+iv contr) are necessary.
