Synchrotron radiation dichromographic imaging of the extra- and intracranial arterial circulations and choroid plexus

This communication proposes the use of synchrotron radiation based k-edge dichromographic imaging for the simultaneous study of the extracranial and intracranial arterial circulations following a single peripheral intravenous injection of a contrast agent. This approach can provide images of the vertebral arteries, the common, external and internal carotid arteries, as well as the intracranial arteries, during a single scanning procedure, lasting only a few seconds, requiring an X-ray exposure on the order of about 30mGy/image. The method has specific advantages for the evaluation of the perfusion of the choroid plexus.
