Cerebral Angiogram Clinical Trial
Official title:
Influence of Contrast Injection Force on the Accuracy of Vessel Measurements in Cerebral Angiography
The purpose of this research study is to collect data/measurements that are routinely collected in standard of care cerebral angiogram
Research for this study is to determine how the injection of contrast material influences
vessel measurements, as these measurements guide device selection when interventions are
warranted.
The data will be used to determine if there is a significant change in vessel diameter with
intra-arterial injection of contrast material in cerebral angiography, how changes in force
of contrast injection augments the significance of the changes in vessel geometry, and the
extent of propagation downstream from the catheter tip that such changes in vessel diameter
are detected and found to be significant, as these changes could potentially lead to less
optimal device selection by providing an overestimation of true vessel diameter.
