Gastrointest Endosc. 2010 Nov 8. [Epub ahead of print] BACKGROUND: The role of EUS for detection of pancreatic neuroendocrine tumors (PNETs) is not clearly defined in institutions that use multidetector CT for pancreatic imaging. OBJECTIVE: The aims of this study were to (1) compare the detection rates of EUS and CT by type and size of PNET and calculate the incremental benefit of EUS over CT, (2) evaluate the CT detection rate for PNETs adjusted for improved CT technology over time, and (3) determine the factors associated with CT-negative PNETs.DESIGN: Retrospective single-center cohort study.SETTING: Johns Hopkins Hospital.PATIENTS: Patients with pathologically proven PNETs with preoperative CT. Incidentally found PNETs (resection specimens) and those without Johns Hopkins Hospital CT imaging were excluded. MAIN OUTCOME MEASUREMENT: Detection rates of CT and EUS were compared by using pathology as the reference standard. leggi l’articolo
