Intracranial Vessel Segmentation in 3D High-Resolution T1 Black-Blood MRI

Sample images of advantageous findings. Identification of the vessel lumen following stent placement during treatment of a ruptured, dissecting aneurysm of the right vertebral artery in a test subject. A, 3D-rendering of rotational DSA in a lateral oblique projection following stent-assisted coiling (arrow, distal stent markers). B, Volume-rendering of the BBMRI model prediction (arrow, vessel lumen within the stent). C, Contrast-enhanced MRA shows partial signal degradation within the stent (arrows). D–F, Correct identification of a small recurrence (arrows) 6 months following coiling of a ruptured right posterior communicating artery aneurysm in a test subject. Volume-rendering in a coronal, oblique view of the BBMRI model prediction (D), of the TOF-MRA (E), and of the contrast medium–enhanced MRA (F).
