Background: Past research suggests that patient-provider relationships play a crucial role in patient satisfaction with their medical care. However, the essential relationship elements responsible for this effect have not been elucidated and were examined in this study.
Methods: Patients in six gastroenterology clinics at a major medical center completed an anonymous, secure Internet survey about their medical care after a clinic visit.
Background Incidental detection of pancreatic cystic neoplasm (PCN) has increased. Since a small percentage of PCNs possess malignant potential, management is challenging. The recently revised American College of Radiology (ACR) recommendations define PCN measurement and growth for different categories based on baseline cyst size.

Methods: One hundred seventeen patients with PCN measuring ≥ 10 mm were included. Three readers independently evaluated MRI with and without the use of apparent diffusion coefficient (ADC).
Objectives: To assess reproducibility of volume and diameter measurement of intraductal papillary mucinous neoplasms (IPMNs) on MRI images.
Methods: Three readers measured the diameters and volumes of 164 IPMNs on axial T2-weighted images and coronal thin-slice navigator heavily T2-weighted images using manual and semiautomatic techniques. Interobserver reproducibility and variability were assessed.
Objectives: To evaluate and compare the accuracy of absolute apparent diffusion coefficient (ADC) and normalised ADC (lesion-to-spleen ADC ratio) in differentiating pancreatic neuroendocrine tumour (NET) from intrapancreatic accessory spleen (IPAS).
Methods: Study included 62 patients with the diagnosis of pancreatic NET (n=51) or IPAS (n=11). Two independent reviewers measured ADC on all lesions and spleen.
Objective: To determine the feasibility of genotyping pancreatic tumors via fine needle aspirates (FNAs).
Background: FNA is a common method of diagnosis for pancreatic cancer, yet it has traditionally been considered inadequate for molecular studies due to the limited quantity of DNA derived from FNA specimens and tumor heterogeneity.
Methods: In vitro mixing studies were performed to deduce the minimum cellularity needed for genetic analysis.
