Criteria for Visual Study Interpretation
| Uptake | Features of tracer accumulation |
|---|---|
| Nonmalignant | Linear, nonfocal limited intestinal uptake with moderate intensity |
| Tracer uptake less intense than liver uptake | |
| Pancreatic head (PET): small sickle-shaped findings in right upper abdomen just below left liver lobe; diffuse nature of uptake | |
| Malignant | Clearly demarked findings with higher tracer uptake compared with liver uptake |
| Tracer accumulation in structures that did not take up tracer physiologically or was higher than background activity | |
| Pancreatic head: irregular or protrusive shape of finding; clear delineation from adjacent tissue with higher uptake than liver uptake |
