Summary
Brief summary (as posted)
1. Imaging findings (including CT and MRI images) of both well-differentiated G3 PNET and poorly differentiated PNET were studied; 2. The CT imaging findings of G3 stage PNET and pancreatic cancer were compared to establish a Logistic regression diagnostic model, and the survival analysis of the two was compared. 3. Cox regression was used to study the risk factors for survival prognosis of well-differentiated and poorly differentiated PNET based on CT image features
