Diagnosis and staging.

Quality of the Evidence	Clinical Recommendation	Strength of the Recommendation	References
Low	In patients with clinical and radiological suspicion of PDAC, pathological confirmation of diagnosis should be considered in the absence of clear signs of malignancy and in patients who are not candidates for surgery	Strong positive	[11,12]
Low	In patients with a pancreatic mass ≥ 2 cm suspected for adenocarcinoma, the execution of a contrast enhanced multislice CT should be considered the first choice for differential diagnosis and staging	Weakly positive	[13,14,15]
Low	In patients with potentially resectable pancreatic adenocarcinoma, MR could improve liver staging	Weakly positive	[16,17]
High	Multislice CT is better than MR for correct definition of non-resectability in patients with pancreatic mass, suspected for locally advanced PDAC	Weakly positive	[16,18,19,20]

Abbreviations: CT—computerized tomography; MR—magnetic resonance; PDAC—pancreatic adenocarcinoma of pancreas.
