7T scanning enables more detailed depiction of anatomy and vasculature comparing to 1.5T and 3T acquisitions. To enhance our understanding of 3D vasculature and its correlation to anatomy, we construct an interactive, electronic atlas with a three-dimensional (3D) model of cerebral arteries from 7T MRI and MRA acquisitions.

A 3D interactive cerebrovascular atlas created from 3T and shown at RSNA 2006 is extended with 7T MRI and MRA scans. The vessels are extracted from 7T MRA and labeled with names. Very small vessels are reconstructed using a dedicated and sophisticated vascular editor. The 3D vascular model is correlated with 7T MRI and MRA scans on the triplanar. Comparison between the 3T and 7T acquisitions and models is done. Tools for manipulation of the 3D vascular model with scan triplanar are developed.

This exhibit: 1) presents an interactive atlas with a detailed, labeled 3D model of cerebral arteries constructed from 7T scans; 2) correlates 3D angiography with 2D neuroanatomy on axial/coronal/sagittal planes; 3) provides real-time manipulation (zoom/rotate/pan) of the vascular model with scan triplanar; 4) compares 7T with 3T scans and vascular models; 5) provides localization and quantification (vessel diameter, coordinates, distances); 6) enhances our understanding of 3D cerebral arteries.
