PET for biliary cancer – pro

PET scanning is a new modality and many questions as to appropriateness and clinical benefit remain. This is especially so in complex anatomic location like biliary and gallbladder carcinoma. It is not at all certain that using PET in gallbladder cancer results in clinically beneficial decisions and false positive and false negative rates have not been adequately studied.ESMo (2016) aSYS: “ The utility of positron emission tomography (PET)-CT is controversial “.SEOM guideline says: “PET-CT may be considered to rule out metastatic disease in patients without metastatic spread on MDCT, but remains investigational [7] (Level of Evidence IIIb, Grade of Recommendation C)”.
