| IDEAL sequence help |
I was given MRI images of the liver of patients, taken with LMS IDEAL optimized low flip. I need to calculate the pdff. I have 72 images per patient with echotime ranging from 1.2ms to 11.2 ms. How do I identify which is the fat, water OP,IN images?
Thank you so much. and yes I am relative new to MRI imaging.
THANKS!

| Proton excitation from B0 to B1 |
I'm new to MRI imaging and currently taking an introductory course online. I understand that the introduction of a small magnetic field/RF pulses on top of the static magnetic field (B0) excites protons into a high energy state (B1). Does this mean that the protons are excited from a spin that is parallel to the longitudinal B0 plane to one that is antiparallel to the longitudinal B0 plane, or that the proton spin is excited from one that is aligned/polarized with B0 to one that is either parallel or antiparallel to B0 in the B1/xy plane?

| When to shim? |
you ask a complex question. Any sequence that is not a standard spin echo can benefit from shimming, but its not always worth it.
If you are scanning a knee in the center of the magnet, or nearly so, you might not see much difference in gradient echo scans, which in general are quite sensitive to shim problems. But if you are doing fat-water separation or fatsat images, you will see a difference even in this example.
Because hardware varies, its hard to say in one blanket statement for every case. For sure, do it on fatsat or fat-water imaging. The next most sensitive studies are off-center imaging such as shoulders. Beyond that, you should experiment a little. Of course, erring on the side of caution is a good idea.
