The signal intensity index is the most reliable evaluation method for differentiating adrenal adenomas from metastatic adrenal tumors.

The most frequently found feature of intraductal papillary mucinous tumors was a lobulated multilocular cystic lesion located in the uncinate process and in contiguity with the dilated main pancreatic duct. In some patients, a bulging papilla and papillary projections in the ducts, which were specific findings, were visualized on CT. The bulging papilla and the caliber of the main pancreatic duct helped differentiate malignant from benign intraductal papillary mucinous tumors.

Texture features IV and SZV, and volumetric parameters MTV and TLG can predict tumour response, but all of them have limited value in prediction of prognosis of patients with esophageal cancer treated by CRT.

These results suggest that whole-body FDG-PET may be useful for detecting AIP and associated extrapancreatic autoimmune lesions and for monitoring their disease activity but that dual time point imaging may not be useful for differentiating malignancy from AIP.
