Analysis of intracranial arteries using an in-house vessel analysis software. (A) Intracranial time-of-flight (TOF) magnetic resonance angiography (MRA) image (FOV, 250 × 250 × 1.2 mm3; voxel size, 0.284 × 0.284 × 1.2 mm3) of a patient with normal intracranial arteries and image processed by region-growing and centerline extraction. (B) TOF MRA and processed image in patients with atherosclerosis of the right middle cerebral artery. FOV field of view.
