Why the study?
What patient-specific factors influence delay time and coronary arterial density during coronary CT angiography with dual-source CT?
What patient-specific factors influence delay time and coronary arterial density during coronary CT angiography with dual-source CT?
Patient-specific factors including heart rate, gender, transversal cardiac diameter, and weight can be used to adjust flow rate and dosage of contrast media during coronary CT angiography.
These associations may inform individualized contrast protocols in dual-source coronary CTA; hypothesis-generating and requires prospective validation.
