Electromagnetic Tracking and Optical Imaging With ICG for Hepatic Biopsies

Background: Liver cancer is the sixth most common cancer worldwide. Diagnosing liver cancer usually requires a liver sample. Getting the best sample helps determine whether cancer is present and what kind of cancer it is. But sampling can be difficult. This study will look at combining two devices to provide better liver samples. Objective: To see if combining fusion imaging and optical imaging can better sample areas of concern in the liver and determine the presence of disease. Eligibility: People ages 18 and older who need a liver biopsy as part of diagnosis or treatment. Design: Participants will be screened with: * Review of imaging * Medical history * Physical exam * Blood test results Participants will have a dye injected into a vein 24 hours before their biopsy. They will be monitored for 30 minutes for any side effects. For the biopsy, participants skin will be numbed. They may have stickers placed on their belly to help guide the needle. They will have a CT scan to plan the needle s pathway. For the scan, they will lie in a machine that takes pictures of the body. A small camera will be placed near the needle to take pictures of the liver. A medical global positioning system (GPS) tracking system will be used. This will guide the needle into the area of the participant s liver where the biopsy will be taken. After the biopsy, participants will recover in the hospital for 4 6 hours. After the procedure, researchers will take the participants biopsy tissue and look at it to try to compare new ways to picture the sample.

* INCLUSION CRITERIA:

In order be eligible to participate in this study, an individual must meet all of the following criteria:

* Patients must have imaging findings consistent with hepatocellular carcinoma or other liver neoplasms or metastasis, for whom image-guided percutaneous biopsy is planned as clinically indicated or Institutional Review Board (IRB)-approved under a separate research protocol.
* Patients must have at least one lesion that can readily be biopsied per Principal Investigator.
* Age \>18 years.
* Patients must have the ability to understand and the willingness to sign a written informed consent document.
* Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they verbally report amenorrhea for 12 months without an alternative medical cause, or have had surgery or received chemicals to induce menopause.

EXCLUSION CRITERIA:

* History of hypersensitivity reactions to Indocyanine Green (ICG), iodinated contrast, or sulfur-containing compounds.
* Pregnant women and nursing mothers are excluded from this study because of exposure to radiation from CT scanning associated with the biopsy
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the Principal Investigator, would limit compliance with study requirements
