  abstract = {The management of neurovascular disease requires precise information
	on the cerebral vascular anatomy. Digital subtraction angiography
	(DSA) is the gold standard against which other imaging modalities
	have to be measured. To improve the quality of three-dimensional
	(3D) magnetic resonance angiography (MRA) images, we present a novel
	concept in 3D image analysis. METHODS: Five patients, harboring cerebral
	aneurysm, underwent DSA, computed tomography angiography (CTA) and
	MRA. MRA data were processed using a novel anisotropic curvature
	motion model. Three-dimensional reconstructions of CTA and MRA datasets
	were used for comparison. RESULTS: The 3D-reconstructed images accurately
	displayed all aneurysms. The anatomy of the anterior part of the
	circle of Willis was visualized reliably. The smoothened vessel surfaces
	enhanced the readability of the images. Regarding visual representation
	of the posterior part of the circle of Willis, the post-processed
	MRA showed the arterial segments less accurate than the standard
	modalities. CONCLUSIONS: This new approach is a promising tool for
	planning of neurovascular interventions and preoperative evaluation.},
