Systems for indicating parameters in an imaging data set and methods of use

An intravascular imaging system, comprising:

• an intravascular imaging catheter configured to be positioned within a lumen of a blood vessel and obtain imaging data of a wall of the blood vessel and a stent surrounding the lumen;
• and
• a processor configured to:
• receive the imaging data obtained by the intravascular imaging catheter;
• determine, based on the imaging data, a respective apposition value of the stent relative to the wall of the blood vessel for each of a plurality of locations of the stent;
• output, to a display in communication with the processor, an image of the stent based on the imaging data, wherein different locations of the stent comprise different visual characteristics in the image, wherein the different visual characteristics are representative of the respective apposition value at the different locations such that the respective apposition value of all of the plurality of locations is displayed in a first manner;
• receive, after outputting the image, a user input identifying a location of the stent on the image;
• and
• in response to the user input, output, to the display, a graphical element proximate to the identified location on the image, wherein the graphical element comprises the respective apposition value corresponding to the identified location such that the respective apposition value of only the identified location is displayed in a second manner, wherein the respective apposition value of all the plurality of locations is simultaneously displayed in the first manner.
