1. A microprocessor-implemented method for assessing hemodynamic information, consisting essentially of: acquiring volumetric coronary vasculature images depicting at least a location and topology of a narrowing of a blood vessel; segmenting the blood vessel from a remainder of the volumetric coronary vasculature images to extract coronary-specific anatomical information representing the geometry of the blood vessel, wherein the coronary-specific anatomical information includes a location of a narrowing of the blood vessel, branch locations of the blood vessel, and a percentage of lumen reduction at the location of the narrowing, such that a localized region based on the location of the narrowing and the branch locations is determined; non-invasively acquiring local blood flow information in at least one or more vessels proximal to the location of the narrowing; quantifying a pressure drop across the narrowing based on the reduced section of the blood vessel and the acquired blood flow using a computational fluid dynamics model configured to receive the geometry of the blood vessel and the blood flow information; calculating a numeric value quantifying a myocardial fractional flow reserve based on the pressure drop; and generating and outputting for review at least the calculated numeric value quantifying the myocardial fractional flow reserve.
