This study aims to determine whether a test, called the PET scan, may be useful in
determining if there are additional locations of cancer not otherwise detectable by other
The PET scan is a nuclear medicine imaging study that measures how much radioactive sugar is
used by your tumor. The study will compare pictures of the cancer from the PET scan to other
x-ray exams, such as a CT scan, as well as to what your doctors find at the time of surgery.
If the study results show that the PET scan gives us a good idea of what is happening to the
tumor, then it may be useful in deciding which patients with colorectal metastases to the
liver should be operated on and what operation should be performed.
Additionally, by comparing the results of PET scans with the other studies that will be
performed as part of your care, we will try to determine which test best tells us which
patient is most likely to benefit from surgery.
