68Ga-DOTA peptide, suspected lesion of the liver, specificity. Clinical history: 52 y.o. male with an incidental detection of a single liver lesion in the left lobe. The lesion is suspect to be a metastasis on ultrasound and CT from an unknown primary site. PET/CT findings: increased focal uptake in a loop of the ileum, suspect to be a primary tumour. Increased uptake in the left liver lobe consistent with a secondary lesion (a MIP, b CT and fused images). After surgery, the lesions were diagnosed to be a well-differentiated NET grade 1 (Ki67 2%)
