Histological analysis of human pancreatic carcinoma following irreversible electroporation in a nude mouse model

Figure 5 Evaluation of therapeutic effects of irreversible electroporation on tumors in vivo by ultrasound. A: A pre-irreversible electroporation ultrasound image showing the normal pancreatic parenchyma; B: The ablation zone showed hyperechoic signals with a comet tail sign in the normal pancreatic tissue (arrow); C: White dots indicate the region of the tumor; D: Ultrasound image showing that the irreversible electroporation ablation zone in the tumor tissue became hyperechoic (arrow). SP: Spleen; LK: Left kidney; P: Pancreas; T: Tumor.
