Abstract:
Objective:To explore the value of magnetic resonance examination in distinguishing invasive and non-invasive pancreatic solid pseudopapillary neoplasms (SPN).Methods:The clinical and MRI data of 167 patients with SPN who underwent surgery and were pathologically diagnosed at Zhongshan Hospital ,Fudan University from Oct 2013 to Oct 2023 were retrospectively analyzed.Results:There was no statistically significant difference between invasive and non-invasive SPN in terms of age, gender, clinical symptoms, laboratory tests, location, growth pattern, tumor size, relationship with the pancreas, bleeding, and pancreatic duct dilation ( P>0.05). However, there were statistically significant differences between the two groups in terms of tumor morphology, margins, capsule, cystic solid ratio, pancreatic atrophy, enhancement pattern, and enhancement features ( P<0.05). The area under the ROC curve for the combined indicators (tumor morphology, margins, capsule, cystic solid ratio, and pancreatic atrophy) was 0.679 (95% CI: 0.594-0.764), with a sensitivity of 73.7% and specificity of 70.9%. Conclusion:Magnetic resonance examination is helpful in distinguishing invasive and non-invasive pancreatic solid pseudopapillary neoplasms.
