MRI and CT of adenomatous tumours of the middle ear.

abstract：PURPOSE:For safe deep brain stimulation (DBS) planning, an accurate visualization and localization of vessels is mandatory. Contrast enhanced (ce) MRI depicts both arteries and veins. Computed tomography angiography (CTA) detects arteries with high geometric accuracy. We routinely combine both modalities for DBS planni...
