* Patients must consent to provide the sponsor with tumor tissue samples from their resected liver metastases.
* Easter Cooperative Oncology Group (ECOG) performance status of 0 to 1.
* Female patients who are post menopausal, surgically sterile, or agree to practice effective methods of contraception from the time of signing the informed consent form through 60 days after the dose of \[68Ga\]MLN6907 or agree to practice true abstinence.
* Male patients who agree to practice effective barrier contraception during the entire study treatment period and through 4 months after the dose of \[68Ga\]MLN6907 or agree to practice true abstinence.
* Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
* Suitable venous access for the study-required, blood sampling (ie, including PK sampling)
* Adequate hepatic function as defined in the protocol.
* Adequate renal function as defined in the protocol.
* Hemoglobin ≥ 9 g/dL.
* Recovery from all adverse effects from prior antitumor therapy to at least Common Terminology Criteria for Adverse Events (CTCAE) (V4.03) Grade 1.

Exclusion Criteria

Patients meeting any of the following exclusion criteria are not to be enrolled in the study.

* Female patients who are lactating and breastfeeding or have a positive serum pregnancy test during the screening period or a positive urine pregnancy test on Day 1 before the first dose of \[68Ga\]MLN6907.
* Any serious medical or psychiatric illness, condition, or personal circumstance, including severe claustrophobia, severe dyspnea, severe back pain, etc., that, in the judgment of the investigator or project clinician, might potentially interfere with the procedures required in this study.
* Involvement in an investigative radioactive or other research procedure within 4 weeks prior to administration of \[68Ga\]MLN6907.
* Major surgery within 14 days prior to administration of \[68Ga\]MLN6907 5. Serious infection (viral, bacterial, or fungal) within 14 days before administration of \[68Ga\]MLN6907 or evidence of active infection during screening.
* Life-threatening illness unrelated to cancer.
* Clinically significant central nervous system (CNS) metastases.
* Known inflammatory bowel disease.
* Known hepatitis B surface antigen-positive or known or suspected active hepatitis C infection (testing not required).
* History of any hypersensitivity to any component of \[68Ga\]MLN6907.
* Symptomatic cardiac disease, including ventricular dysfunction, coronary artery disease, or arrhythmias, if this would, in the opinion of the investigator or project clinician, interfere with assessment of efficacy or safety of \[68Ga\]MLN6907.
* Admission or evidence of addictive disorders (eg, illicit drug use, drug abuse, or alcohol abuse) that would limit compliance with study requirements.
* Inability to lie flat for the duration of image acquisition.
