Purpose
- Pancreatic CT perfusion with a biofeedback breathing belt worn by the participant, and using novel post-processing techniques, is a reliable method which can be used to differentiate between pancreatic cancer, chronic pancreatitis, and autoimmune pancreatitis.
- Pancreatic CT perfusion can be used to monitor patients undergoing decompression treatment (endoscopic retrograde cholangiopancreatography with stent placement) for painful chronic pancreatitis, and the change in the pancreatic perfusion parameters correlate with the change in the pain parameters (pain scale and analgesic use).
- Pancreatic CT perfusion parameters can be calculated using surrogate scan data sets at specific time points to replace the continuous scanning.
