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 MIP (a) and VR (b) TOF MR angiography images show absence of the left AICA, well-developed left PICA, and moderately developed right PICA in a 48-year-old woman. <i>Thick long arrows </i>= right and left PICAs, <i>thin long arrow </i>= right AICA, <i>thick short arrows </i>= right and left SCAs, <i>thin short arrows </i>= right and left PCAs, and  <i>R</i> = right.</table>
