1 Transforaminal transcranial color-coded duplex sonograms before (left) and after (right) application of an echo-enhancing agent. Transforaminal transcranial color-coded duplex sonograms before (left) and after (right) application of an echo-enhancing agent. VA indicates vertebral artery; BA, basilar artery; PICA, posterior inferior cerebellar artery. Before echo enhancement, an occlusion of the intraforaminal part of the vertebral artery might have been falsely assumed. Erwin Stolz et al.
