Pre-op staging of primary bowel cancer

The use of PET-CT as an additional imaging modality during pre-operative staging of primary bowel cancer has little evidence to support it, according to research published in Health Technology Assessment. Its use was cost-effective in pre-operative staging of recurrent colon, recurrent rectal and metastatic disease, but not in primary colon or primary rectal cancer.
