Images in a 55-year-old patient show hepatitis C-related cirrhosis and a transjugular intrahepatic portosystemic shunt (dashed arrow), with an undiagnosed tumor (dashed circle) at pretransplant imaging by both readers. Left: Noncontrast-enhanced axial CT image with a treated observation (dashed circles on the left, middle, and right images) and dense lipiodol staining (arrows) in the anterior right liver. Middle: Late arterial phase CT image with no appreciable enhancement. Right: Delayed phase image with no appreciable washout. The lesion was deemed at explant pathology to have 20% necrosis.

FDOPA-PET/CT predicts survival in patients with midgut NETs
By Will Morton
PET/CT imaging with F-18 fluorodopa (FDOPA) is an effective approach for detecting neuroendocrine tumors (NETs) -- and now the scans may be used to predict survival in patients with tumors in the midgut, according to researchers in France.
