Systems and methods for multi-modal imaging using an endoscope having an instrument channel, where the imaging is achieved without using the channel, are disclosed. The systems can include a multi-modal imaging paddle housing couple to a distal end of the endoscope. The housing can receive at least two imaging probes. The imaging probes can be an angle-resolved low-coherence interferometry probe (a/LCI) and an optical coherence tomography (OCT) probe. The housing can be scaled and positioned to be visible via the endoscope camera. The system and method can include locating the housing in a region of interest using the endoscope camera, acquiring OCT measurements to identify targets, and then acquiring a/LCI measurements at the identified targets.
