| Plz Answer this ... Contrast MRI of Brain |
Pre and Post contrast mri of the brain was performed in multiple planes using T1 & T2 W spin-echo sequence.
There is small ring enhancing lesion in the left occipitoparietal lobe which measures 1cm in diameter.It reveals isointense periphery on T1 & T2W images with hyperintense core on T2W images. On T1W images the core appears hypointense . A tiny mural nodule is seen within the lesion. focal perilesional edema is seen appearing hyperintense on FLAIR and T2W images.
The brainstem & cerebellum are normal.
The ventricular system is normal.
No abnormal meningeal enhancement is seen.
Intracranial vessels display normal flow void.
What needs to be done?? How serious the problem is??

| 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...
