This study provides useful insights into using ultrasound for diagnosing acute pancreatitis, but a couple of things could use more clarification. Since there was a high false positive rate (48 cases), could the authors discuss what might have contributed to this? For example, was operator skill or variability in interpreting ultrasound results a factor? Also, while CT was used as the gold standard, were any other confirmation methods, like MRI or biochemical markers, considered?
