| What´s this in L3? |
You just give t2 sagital WI, that not enough for determined what the problem in L3 spine, better you asked to radiologist and show all the MRI picture. Cause i saw there lession in corpus L3 and bulging in discus L3-l4 (HNP). To know more about something in Corpus L3 you must have all sequence in MRI Lumbal exam.

Hi Oscar
The basic for head exam
Ax T1-WI, Ax T2-WI, Ax-Diffusion(DWI), Ax Flair, Cor T1 or T2, Sag T1 or T2, if any lession and suspect tumor, u can give Ax T1, Sag T1, Cor T1 with contrast injection.

| fluid PD vs T2 weighting |
The truth is basicley that different tissues have different relaxation times, the signal of fluid last longer than fat in a T2, so it appears bright.
But also with a "short" TE of 30ms you can already achieve a high signal of fluid, but this is highley dependend of the TR. A long TR - 5000ms - will give you a high signal of fluid. But scantimes won't be acceptable...

| ETL for a STIR |
It depends.
When Centric echo allocation is used you have higher SNR, a low TE, but more image blurring. Very similar to a PD. I prefer an echo train of less than 8 in this case.
When Sequential echo allocation is used you have lower SNR, a higher TE (I prefer less than a TE of 60), but significantly less image blurring. Very similar to a T2 or FLAIR. In this case your echo train length is governed by your TE and image blurring is not usually an issue. Depending on how short of an inter-echo time you can use, and by keeping an eye on the TE, the echo train can be as high as you want.
Hope this helps.
