Pancreatic cystic lesions are a frequent incidental finding in abdominal imaging. Despite its usually benign background, a small fraction exhibiting features suspicious for cancerous development demands continuous follow-up or surgical removal. Current guidelines advocate magnetic resonance imaging and endoscopic ultrasound to evaluate the risk of malignancy, whereas transabdominal ultrasound is perceived as subordinate imaging. The objective of this study was to analyze cyst detection rates of latest-generation ultrasound machines compared to magnetic resonance imaging, computed tomography, and endosonographic ultrasound and to determine inter-rater reliability. The results showed that large cysts facilitate their visualization by transabdominal ultrasound while detection rates are independent of the anatomical part of the pancreas in which they were sited. Changes in the pancreatic duct width, a connection to the pancreatic duct system, and the architectural characteristics of cysts are poorly recognized by transabdominal ultrasound compared to magnetic resonance imaging and endoscopic ultrasound. Computed tomography imaging is preferred over transabdominal ultrasound to detect calcifications and regional lymphadenopathy. Even if conducted by experienced investigators, transabdominal ultrasound examinations fail to agree with magnetic resonance imaging scans regarding cyst detection rates (κ = 0.093).
