Devices, systems, and methods for visually depicting a vessel and evaluating treatment options are disclosed. A method of evaluating a vessel of a patient, comprises: obtaining intravascular data from an intravascular instrument positioned within a vessel of a patient while the intravascular instrument is moved longitudinally through the vessel from a first position to a second position; obtaining an angiographic image of the vessel while the intravascular instrument is moved longitudinally through the vessel; correlating the intravascular data from the intravascular instrument to locations on the angiographic image; and outputting an enhanced angiographic image of the vessel on a display, the enhanced angiographic image including the angiographic image overlaid with visualizations representing the intravascular data at the correlated locations. Corresponding systems are also provided.
