CONTRIBUTION OF 3D RECONSTRUCTIONS IN ANG IOGRAPHIC ASSESSMENT OF BRAIN VASCULAR MALFORMATIONS - 3D MORPHOMETER

The need for medical images which can directly contribute to therapeut ic decision making has led to the development of 3D visualization tech niques. With this objective, a procedure capable of producing 3D volum e reconstructions using isotropic voxels from digitalized 2D films obt ained by rotation around the object has been developed: 3D morphometry . The technique has been assessed from 1993 through 1996 for vascular malformations in the brain, particularly aneurysms. Recognition of col lateral vessels originating at the malformation was helpful in better identifying the lesions and evaluating possible therapeutic difficulti es. The morphometric sequence thus is a possibility for the future ass essment of neurovascular arches.
