Representative patient on PET/CT (False-Negative) compared to CEMR (True-Positive): A 37-year-old female experienced epigastric pain for 4 months. Serum CA19-9 was elevated (259.4 U/mL). (A) The body and tail of pancreas were slightly swollen with slightly increased ¹⁸F-FDG uptake (SUVmax 3.1). There was insufficient evidence of malignancy on PET/CT especially when no other significant abnormality was identified on the rest of the body scan. (B) CEMR showed a low-signal area on T1WI with narrowing of the pancreatic duct in the body and tail of pancreas which has no significant density change on PET/CT due to relatively limited resolution. The lesion enclosed retroperitoneal vessels which was suggestive of pancreatic cancer. Biopsy result showed adenocarcinoma (differentiation unspecified). Patient died after 9.2 months.
