EUS is superior to secretin-enhanced cholangio-MRI to establish the etiology of idiopathic acute pancreatitis.

The etiology of idiopathic acute pancreatitis (IAP) should always be defined. Our aim was to compare the diagnostic value of endoscopic ultrasound (EUS) versus secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) in patients with IAP. Patients admitted to a single tertiary care University hospital with IAP were invited to participate in the study.

[Preoperative staging MRI for rectal cancer and pathologic correlation].

Background: Our aim is to asses the accuracy of MRI for preoperative rectal cancer staging and to establish a histopathologic correlation.

Methods And Materials: A retrospective analysis was performed on 120 patients aged between 43 and 87 with histologically proven rectal cancer who underwent MRI for preoperative staging in our hospital between 2005 and 2010. Patients were categorized according to the TNM classification.
