Examples of true and false positives and negatives with [18F]PSMA-1007 PET/CT. a True positive [18F]PSMA-1007 PET/CT with low grade uptake in two lymph nodes along the right external and internal iliac vessels. PAD showed one 5 mm metastasis from the right side (presumably from the internal iliac since the lymph node along the external vessels measured 12 mm and was PSMA + in its entirety) and one 1,5 mm from the left (not detected by PET/CT). b False positive [18F]PSMA-1007 PET/CT with low grade uptake in one lymph node along the right external iliac vessels. c True negative [18F]PSMA-1007 PET/CT with low grade uptake in several lymph nodes along the external vessels bilaterally. d False negative [.18F]PSMA-1007 PET/CT with faint uptake in three lymph nodes along the external vessels bilaterally (only on shown in image)
