9. A method implemented by a system of one or more processors, the method comprising:
accessing a computerized model representative of vascular segments of a patient, wherein the computerized model comprises one or more stenosed vascular segments and a plurality of normal vascular segments,
generating an unstenosed computerized model based on virtually enlarging the plurality of stenosed vascular segments of the computerized model based on widths of the plurality of normal vascular segments,
determining, based on the computerized model and the unstenosed computerized model, metrics associated with one or more vascular locations along the enlarged plurality of stenosed vascular segments, wherein the metrics include (1) a number of branching points, (2) geometry information associated with individual aspects of the vascular locations, and (3) tortuosity of the vascular locations,
determining, based on blood flow parameters of the computerized model and the unstenosed computerized model, a severity for at least one of the one or more stenosed vascular segments, and
causing a user interface to display the severity of the at least one stenosed vascular segment and stenosis information, wherein the stenosis information is based on conversion of the metrics to one or more vascular state scores.
