Survival outcomes in asymptomatic patients with normal conventional imaging but raised carcinoembryonic antigen levels in colorectal cancer following positron emission tomography-computed tomography imaging
Newly published data indicate the sensitivity of 18F-fluorodeoxyglucose (18F-FDG)–PET for the detection of recurrent disease. A total of 88 patients with no, or equivocal signs of recurrence on clinical examination, but who had raised carcinoembryonic antigen (CEA) levels were examined using 18F-FDG–PET. Read more.
