A Pilot Study of Optical Molecular Imaging for Percutaneous Biopsy of Hepatocellular Carcinoma Using Indocyanine Green

This research study is evaluating an imaging contrast agent called indocyanine green, also known as ICG, in combination with image guided liver biopsies. In this research study, the investigators are looking at the ability of ICG to collect within liver tumors during biopsy. The participant will be receiving a biopsy of their liver as a part of their medical care. By participating in this trial, the only additional requirement will be for the participant to come to the hospital on the day prior to their scheduled biopsy to receive an injection of ICG. During the biopsy, the investigator will measure the amount of ICG that is in the participant's liver tumor by using two experimental devices designed by the study investigators that shine light on tissue. One device consists of an imaging system attached to a small borescope that will go inside the participant's body during the biopsy. The second device shines light on the biopsy sample outside of the participant's body after the biopsy has been taken. The participant may undergo imaging with one or both of these devices.
