Fluoro-2-deoxy-D-glucose (FDG) PET scanning is a 'sensitive tool', which can identify undetected cancer and help doctors decide to perform hepatic resection, doctors reported.
Doctors led by Dr Steven Strasberg at Washington University, St Louis, Missouri, USA, tested the sensitivity of FDG-PET scanning on 43 patients after carrying out staging using CT scans.
The FDG-PET scans detected cancer in 10 patients who had been reported as clear by CT scans, they report.
A total of 35 patients underwent resection. The overall survival rate of patients after 3 years was 77 per cent - higher than rates found in other studies, according to the researchers.
"Preoperative FDG-PET lessens the recurrence rate in patients undergoing hepatic resection for colorectal metastases to the liver by detection of disease not found on conventional imaging," the researchers write.
