2D / 3D MRI for brain tumors diagnosis
Hello

I am a research master student, my thesis on artificial intelligence and MRI in the process of diagnosing brain tumors, the objective is to determine the type of tumor in the image.

I have not found the advantages of using a 2D image in the diagnostic process instead of 3D images, since the 3D image is richer and can be copied into two dimensional slices as well.

What role does the 2D image play in the tumor diagnostic process ?

MRI Markers for Brain imaging
Does anyone use MRI markers in which the hair does not have to be shaved to attach the marker for MRI imaging of the brain? We will be scanning adolescents and do not want to shave their hair for marker placement. We thought vitamin E capsules but don't know how to "glue" it to the scalp in the precise location without shaving the hair. Also we don't want the glue to dissolve the capsule. The marker only needs to stay attached for MRI scan and then can be removed. Thank you!

Gadolinium - blood brain barrier
Does Gadolinium cross blood brain barrier? I am having a neck and spine MRI with Gaolinium contrast for detection of CSF leak. Can intravenous vein administration of Gadolinium get into the neck and spinal cord?

Brain T2FS postcontrast
What is the advantage of T2 FS imaging of the brain if 3 planes of postcontrast T1's are obtained.
Thanks.

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??
