In particular, it is likely to be useful in comparing pre- and post-treatment acquisitions where we are trying to see how flow has changed not just through arteries, but also in the brain parenchyma.
This time is thenrepresented by a color. The DSA section you wish to review can easily be selected within the syngo iFlow function. Notice the color of theat the origin of the left MCA with marked large vein of Labbe and the middle cerebraldecreased perfusion of the left MCA territory. TreatmentPercutaneous transluminal angioplasty andstenting were performed without adverseevents. Flow into the left MCAterritory was markedly improved.
The color-coded image doneDSA showed a mm right middle cerebral at the end of treatment shows much earlieraneurysm, a 1. Notice the green color in theTreatment internal carotid artery on the pre-treatmentBoth aneurysms were coiled and the image and the orange color in the same arteryvasospasm was also treated.

DSA done prior to pre-operative embolization The color-coded image of a selective occipitalshowed a typical pattern of vascularity with artery injection 1b is particularly useful insupply to the tumor from the ipsilateral occipi- showing the venous drainage from the tumor. Following embolization the occipital artery green arrow ; all of thesethere was no longer any tumor stain and no structures have the same color, indicatingabnormal venous drainage.

Dural arteriovenous fistulaHistory Commentsyear-old male with a 5-year history of Thanks to the composite nature of syngotrigeminal neuralgia. The composite nature of thethen into the straight sinus and the transverse color-coded image clearly depicts the relation-sinus.
MCA occlusionHistory Commentsyear-old male with acute left hemiparesis. MRI performedone day after treatment revealed infarction ofthe right striatum. At no added X-ray dose or contrast medium, it improves the conspicuity of findings on DSA images. It seems particularly useful in situations where there are complex flow patterns as well as in evaluating acquisitions done prior to and after a therapeutic intervention.

Separate origins of the left internal and external carotid arteries from the aortic arch and cervical internal carotid artery aneurysm in a patient with Noonan syndrome. Distinct origins of the external carotid artery and the internal carotid artery ICA from the aortic arch have been rarely described, and represent an aberrant development of the aortic arches during fetal life. This anatomical variation is usually discovered incidentally; infrequently, an aneurysm of the cervical ICA might accompany this rare configuration. We describe one such case in a patient with Noonan syndrome who presented with pulsatile neck mass.
