This study is investigating new ways to better identify and understand pancreatic tumors. The main focus is on pancreatic adenocarcinoma (PA), a common and serious type of tumor, and pancreatic neuroendocrine tumors (pNETs), which are rare but becoming more common. Endoscopic ultrasound (EUS) is a special imaging technique that helps doctors see tumors better. It uses sound waves to create pictures of the inside of the body. This study is trying two new ways to improve EUS: Superb Microvascular Imaging (SMI), which helps see the blood flow in tumors, and Shear Wave Elastography (SWE), which measures how stiff the tumors are. These methods may help doctors figure out if a tumor is dangerous and decide the best treatment.

• This study involves imaging techniques, not treatments.
• Participants must be 18 years or older and speak French.
• Women who are pregnant or breastfeeding cannot join.
