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 posteroanterior view VR (b) computed tomography (CT) angiography images show absence of the right PICA and well-developed right AICA and left PICA in a 54-year-old man. The images also depict a dominant left vertebral artery. <i>Thick long arrow </i>= left PICA, <i>thin long arrows </i>= right and left AICAs, <i>thick short arrows </i>= right and left SCAs, <i>thin short arrows </i>= right and left PCAs, and <i>R</i> = right.</table>
