Is the Calcium Score a Good Predictor of Coronary CTA?

There is a significant fraction of patients in which we think that calcium score is basically zero as a per Agistome technology. So there is already a gray zone that we don't explore using current protocols. And also I wanted to ask you what is your opinion on calcium density? Because that's something which is not really captured with the Agat some methods. That is yeah, I think the role of Agat some score was more a synthetic expression of black burden and cardiovascular risk.
