Comparison of contrast-enhanced ultrasonography and magnetic resonance imaging in displaying anatomic features of cystic pancreatic masses

Purpose: To compare the accuracy of ultrasound (US), contrast-enhanced ultrasonography (CEUS) and Magnetic Resonance Imaging (MRI) in displaying anatomic features of cystic pancreatic masses greater than 1.5mm. Materials and methods: US, CEUS and MRI examinations of 33 patients who underwent resection for a cystic pancreatic mass were retrospectly reviewed. Two radiologists, blinded to the final histologic diagnosis, reviewed the studies specifically assessing the presence of either intralesional mural nodules or septa. Sensitivity (Se), specificity (Sp), positive (PPV) and negative (NPV) predictive values and a…
