Arterio-venous malformations (AVMs) of the brain are usually easy to evaluate and diagnose on MRI. Once in a while though prior to treatment, a 3D model may be of help in evaluating the anatomy.
This is a young patient with a pericallosal AVM. The 3D model obtained after an angiogram shows the feeding artery and draining vein exquisitely, making surgical planning and intervention easy.
