1. A system for assessing vasculature of a subject, the system comprising:
- one or more processors in communication with an intraluminal device comprising a sensor configured to obtain functional flow data while positioned within the vasculature, wherein the one or more processors are configured to;
receive the functional flow data from the sensor;
receive an external image of the vasculature;
determine a functional flow parameter at a plurality of locations along the vasculature based on the functional flow data;
determine an alert when the functional flow parameter exceeds a threshold level at a location of the plurality of locations along the vasculature, the threshold level associated with a disease state of the vasculature;
output, to a monitor in communication with the one or more processors, the external image comprising;
the vasculature comprising different colors based on the functional flow parameter at the plurality of locations, the different colors corresponding to different threshold levels of the functional flow parameter; and
an indicator corresponding to the alert and displayed on or adjacent to the location along the vasculature identified by the alert such that the indicator visually links the location to the functional flow parameter at the location.

Abstract
The invention provides systems and methods for assessing the vasculature of a subject. In certain aspects, systems and methods of the invention involve receiving functional flow data of a subject via a data collector co-located with a radiopaque label, receiving imaging data of the vasculature including the radiopaque label, generating a vasculature map corresponding to the functional flow data, and displaying the vasculature map image on a monitor.
