This is a proof of concept study and the results apply to the FLASH scanner. This is what makes the FLASH scanner so fast.

This is a very innovative concept giving a different use to the second beam source in DSCT. This proof-of-concept shows the capacity of the scanner to create diagnostic cardiac images (not necessarily of the coronaries) minimizing the radiation dose – however, at the expense of the temporal resolution. This technique appears very promising for the younger patient with a low suspicion of CAD and a low regular heart rate.

High-pitch CTA has real potential for vascular imaging – even without ECG-gating. Very fast, Very low dose.
