In vivo experimental setup for a proof-of-concept of prostatic nerve imaging using near-infrared cyanine VSD: (a) in vivo experimental protocol. (b) The validation of no adverse effect of the direct VSD administration using intracavernosal pressure (ICP) measurements before and after the electrical stimulation in control and VSD groups. (c) Corresponding observation of erectile function at each experimental phase (Movie 1).
