Maximum standardized uptake value (SUV
) in malignant intraductal papillary mucinous neoplasm (IPMN) and benign IPMN. (a) There is a significant difference in SUVmax between malignant IPMN and benign IPMN non-parametrically, P < 0.01. The number in each column is the mean SUVmax ± standard deviation. (b) Receiver operating characteristic curve in malignant IPMN and benign IPMN. The area under the curve is 0.933.
