1. A system for visualization in a light deficient environment comprising:
an endoscope;
an emitter for emitting a plurality of pulses of electromagnetic radiation for providing illumination in the light-deficient environment;
an image sensor comprising a pixel array that detects electromagnetic radiation and outputs data for generating a plurality of exposure frames; and
a controller in electronic communication with the image sensor and the emitter configured to synchronize timing of the emitter and the image sensor to generate the plurality of exposure frames;
wherein at least a portion of the plurality of pulses of electromagnetic radiation emitted by the emitter comprises a fluorescence excitation wavelength; and
wherein at least a portion of the plurality of exposure frames comprise a fluorescence exposure frame.
