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.
