Abstract Objective To evaluate the characteristics of enhanced MRI and enhanced CT in focal advanced pancreatic cancer (LAPC) treated with irreversible electroporation (IRE) and to explore the relationship between these characteristics and the progress of tumor recurrence. Methods Qualitative and quantitative analysis of 25 cases of LAPC patients treated with IRE image data. The imaging features of enhanced CT and enhanced MRI at ablation level during 6 months follow-up were evaluated. The scores of intensification before and after treatment were compared. The characteristics of CT density at 6 weeks and 6 months
