1. A method of evaluating a vessel of a patient, comprising:
- introducing a first instrument into the vessel of the patient;
introducing a second instrument into the vessel of the patient;
moving the second instrument longitudinally through the vessel of the patient from a first position to a second position while maintaining the first instrument in a fixed longitudinal position with respect to the vessel;
obtaining pressure measurements from the first and second instruments while the second instrument is moved longitudinally through the vessel;
calculating pressure ratios of the pressure measurements obtained by the second instrument to the pressure measurements obtained by the first instrument;
visually depicting the pressure ratios on a display, wherein the visual depiction of the pressure ratios comprises a graph including a graphical representation of the pressure ratios; and
modifying the graph to simulate one or more treatment options, wherein modifying the graph comprises changing a shape of the graphical representation in the graph to simulate an increase in the pressure ratios resulting from the one or more treatment options.
