A method to inspect a solid organ in a subject includes introducing a needle in a predetermined area of the solid organ, inserting an optical probe through a lumen of the needle, and imaging the predetermined area using the optical probe. An optical probe to inspect a solid organ in a subject, the optical probe being intended to be positioned in the solid organ through a needle, the optical probe includes an optical fiber bundle, a ferule to protect the distal tip of the optical fiber bundle, the ferule comprising a shank and a head, and a sheath wrapping the fiber bundle and the shank, wherein the head of the ferule has a length adapted for the optical probe to image the solid organ while keeping the sheath inside the needle.
