The Value of Contrast-Enhanced Ultrasound Classification in Diagnosis of Pancreatic Cystic Lesions
Table 1
CEUS diagnostic criteria for common pancreatic cystic lesions.
| Diseases | CEUS criteria | MRI criteria |
| Pancreatic carcinoma with cyst degeneration | In the arterial phase, lesions enhance later than the pancreatic parenchyma and is hypoenhanced, with signs of metastasis | In the arterial phase, lesions enhance later than the pancreatic parenchyma and is hypoenhanced, with signs of metastasis |
| SPT | The lesion is ring-shaped and enhanced in the arterial phase, the solid parts can be enhanced, and there are cystic nonenhanced parts inside | The lesion is ring-shaped and enhanced in the arterial phase, and there are cystic parts or calcification or bleeding inside |
| IPMN | Polycystic lesions are connected to the pancreatic duct, and solid nodules can be seen inside | Polycystic lesions are connected to the pancreatic duct, and solid nodules can be seen inside |

SCN: serous cystic neoplasm; MCN: mucinous cystic neoplasm; SPT: solid pseudopapillary tumor; IPMN: intraductal papillary mucinous neoplasm.
