AB  - PURPOSE: To determine the normal anatomical features and variations of the 
      vertebrobasilar circulation and its branches in patients who underwent 
      multidetector computed tomography (CT) or magnetic resonance (MR) angiographies 
      of the brain. METHODS: 135 patients (male, 83 and female, 52; mean age, 50.1 
      years) who underwent CT (n = 71) or MR (n = 64) angiographies of the 
      vertebrobasilar vasculature for various reasons were analyzed retrospectively. 
      The right and left distal vertebral arteries (VAs), posterior inferior cerebellar 
      arteries (PICAs), anterior inferior cerebellar arteries (AICAs), superior 
      cerebellar arteries (SCAs), posterior cerebral arteries (PCAs), and posterior 
      communicating arteries (PCoAs) were analyzed individually. RESULTS: In 24.4% of 
      the cases (33/135) right PICA, in 19.3% of the cases (26/135) left PICA, in 17.8% 
      of the cases (24/135) right AICA, and in 18.5% of the cases (25/135) left AICA 
      were absent. In cases without PICA or AICA, there was a statistically 
      significant, moderately or well-developed AICA or PICA on the same side, 
      respectively (P < 0.001). The most common variation was isolated absence of right 
      PICA and was seen in 17.8% of the cases. CONCLUSIONS: The anatomic features of 
      the branches of the vertebrobasilar circulation may be different from well-known 
      normal anatomy. CT and MR angiographies allow a precise and detailed evaluation 
      of vertebrobasilar circulation.
