Normal Anatomical Features and Variations of the Vertebrobasilar Circulation and Its Branches: An Analysis with 64-Detector Row CT and 3T MR Angiographies

<table>Oblique coronal view maximum intensity projection (MIP) (a) and volume-rendered (VR) (b) time-of-flight (TOF) magnetic resonance (MR) angiography images show normal anatomy of the vertebrobasilar circulation in a 20-year-old woman. <i>Thick long arrows </i>= right and left posterior inferior cerebellar arteries (PICAs), <i>thin long arrows </i>= right and left anterior inferior cerebellar arteries (AICAs), <i>thick short arrows </i>= right and left superior cerebellar arteries (SCAs), <i>thin short arrows </i>= right and left posterior cerebral arteries (PCAs), <i>arrowheads</i> = right and left posterior communicating arteries (PCoAs), and <i>R</i> = right.</table>
