Basilar artery (BA) and the outlet angle of the superior cerebellar artery (SUCA) Assessment of the BA length and bifurcation height and SUCA outlet angle. a) A 57 year old male control patient with normal height of the BA bifurcation (grade 0 according to Smoker criteria [8]) and nearly perpendicular SUCA outlet from the basilar artery (angle right: 85°, angle left: 75°; SUCA outlet angle of 160° as defined by sum of left and right side). b) A 61 year old female LOPD patient with dilated basilar artery, cranial shifted BA bifurcation indenting the third ventricle and hypothalamus (*, grade 3 according to Smoker’s criteria [8]) and low SUCA outlet angle (angle right: 48°, angle left: 31°; SUCA outlet angle of 79° as defined by sum of left and right side). Schematic drawings indicate measurements of SUCA outlet angles (red angles) and measurements of basilar artery: anatomic length (line a) and linear length (line b)
