Overview
Other Imaging Findings
PET scan
Cancer cells in the body grow rapidly, so they absorb the radioactive sugar fluorodeoxyglucose or FDG used in Positron emission tomography. Location and extent of the tumor mass can be determined using PET scan. Metastatic lesions and their locations can be assessed well using a PET scan.
PET scans are evolving as a very useful modality for staging and assessment of colorectal cancers. PET-CT scan has the advantage tissue based resolution and is useful in detecting whole body metastasis.
Barium Study
Barium study can be used to delineate the lesion preoperatively.
