The study is a prospective trial of CE- EUS in which the conventional EUS that is part of standard clinical care is conducted after injection of intravenous contrast agent. The study population will include those patients already undergoing endoscopic ultrasound for standard pancreatic indications at Cedars-Sinai Medical Center. The primary procedures will include conventional EUS to evaluate a pancreatic lesion as part of standard of care, IV contrast agent during the procedure if deemed necessary by the investigator, collection of time intensity curves for pancreas and lesions from the EUS processor. The study includes one standard of care visit for EUS, and the enrollment period will be 24 months. All enrolled patients will be followed by chart review or phone call for a period of 12 months. All of the subjects will be undergoing an EUS for standard of care. These patients will also receive an IV contrast agent (Lumason) during the procedure, which is not part of standard of care, and is for research use only. FNA will be performed only on those patients deemed to require FNA based solely on the standard EUS. If the aims of the study are achieved, it ill confirm that contrast-enhanced EUS can be used to differentiate various pancreatic lesions and, in future, may aid in risk-stratification of precursor lesions for pancreatic cancer.
