Editor's Notes
- An example of that, then, is this carotid study. This was a 90 year old patient, who had a failed Doppler TIA, and if you look at the study, you will see that they covered 338mm in 4.2 seconds. So a 90 year old patient, it was a comfortable breath hold, 4.2 seconds as opposed to what would have been probably about a 16 second scan on a 16 slice scanner. Clearly, you can see the area of infarc on the right carotid as depicted also in the rotating movie for the clinician. So they’re starting to interrogate this data much differently, getting it more in a pure arterial phase with very little venous contamination, something that they’ve been wanting to do for quite some time, and the LightSpeed VCT is now able to deliver that capability.
