information needed
Andre,

You can do a PD sagittal and/or T1 coronal. These two would give you meniscii tears, just magnify them and brighten the image to show the tear. You can also try the T2 STIR coronal to show some swelling and bone contusion. Check with your rad to find out proper protocols.

STIR sequences
Well, a STIR technique is T1 weighted, so, TR will be short.

MRI Bandwidth and turbo factor relation ?
HI !
question)

we used hostipal Siemens Avanto 1.5T

I didnt know MRI Bandwidth and turbo factor relation ?

T1,T2,PD etc.. accoding to sequence Bandwidth and turbo factor relation

and T1, T2 appropriate Bandwidth and turbo factor relation ?

Please advice

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??

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.
