| How to fill the K-space? |
Hi,
i've been learning MRI for some weeks, and i really want to know that when we use the spin-echo sequences, how can we fill the data into K-space line by line?
i learned the steps of spatial encoding, but i need the algorithm, or the equations, or the quantitative way to fill the K-space.
thanks a lot!

| How does TE affect DWI acquisition? |
Hi folk! Just a breath question: how does TE affect conventional sequence (single shot SE-EPI) for DWI acquisition? In particular, how would two acquisitions differ from each other if acquired with TE=90/106ms respectively (being equal all the other parameters, i.e. TR=11s, same FOV, …)? Thanks for any opinion you will give me. Danilo.

Easy!!! If you have been working in the field for a while and use the MIC, MRI in practice and any other review book you are set. I had like only 2 math problems and even those were both calculating scan time. Tons of anatomy and the rest dealt with GRE sequences (steady state, spoilers etc) Maybe I was lucky and got the less difficult test but if you are about to take it, don't freak out.

| Imaging of the sacral plexus |
We are students Technical Medicine from Twente University and are researching the imaging of the anatomical variation of the sacral plexus. This means the imaging of nerves in a fatty/muscle enviroment with a diameter below 1 mm.rnrnWe are interested in different MR-sequences that will show these small nerves (at the moment we came up with MP(2)Rage, STIR, normal SE T1 and DW) Does anybody can provide us why we should or shouldn't use one of these sequences. Or maybe somebody does have a better suggestion?rnrnAlso we were planning to combine spinal and abdominal coils (phased-array RF coils), does this depict the sacral plexus in a good way?rnrnWe also thought about using a 7T MRI scanner, because of the high spatial resolution. Is this a possibility or does it give to much artifacts? Or is the spatial resolution in a 3T machine enough for such small nerves?rnrnThanks in advance!

For a better result of MRCP, a patient should be NPO for abt 6 hours.Then just five minutes before starting the scan,pure pineapple juice(500ml)is given.Magnesium found in pineapple, acts as oral contrast in biliary tract thus gives a sharp and bright clear image.For the sequence breath hold should proper.
