Means and standard deviations for the average radius (AVRAD) in mm, tortuosity as measured by the Sum of Angles Metric (SOAM) in radians/mm, and tortuosity as measured by the Inflection Count Metric (ICM) as a dimensionless number for the left carotid (LCar), right carotid (RCar), basilar, left middle cerebral artery (LMCer), right middle cerebral artery (RMCer), and anterior cerebral arteries (Ant Cer) for 10 healthy mice.
