1. A method for determining a functional significance of coronary artery stenosis comprising:

  • gathering patient-specific data related to concentration of a contrast agent within a coronary artery of a patient;

    using the patient-specific data to calculate a patient-specific transarterial attenuation gradient for the coronary artery of the patient; and

    comparing the patient specific transarterial attenuation gradient to previously collected data to determine an estimate of a pressure gradient for the patient.
