Cerebral vessel segmentation

Support
1

Hi,

I was wondering if there was a method or a module in 3d Slicer to segment out cerebral vessels (cortical and/or subcortical) from a gado enhanced MR scan and to build a 3d model out of it. Is the VMTKVesselEnhancement module the appropriate one to use?

Thanks for your help.

Sure, if the contrast is good then pure thresholding might even work, but enhancing the vessels first could help.

Have a look at the segmentation materials:

Exactly, the contrast we use in the MDTC is ultravist, or any other iodine-based as Ray Diagnostic apparatuses, with a dose of 1 ml/kg.

Exacto, el contraste que empleamos en el MDTC es el ultravist, o cualquier otro con base a yodo como iopamiro, con una dosis de 1 ml/kg.

Great thanks! I’ve used the Seg Editor before for segmenting out electrodes based on threshold effect. I’ll see if this works for the enhanced vessels in the scans I have.
