ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of contrast-enhanced ultrasound in the differential diagnosis of solid focal lesions of pancreas (s-FLPs).</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 56 s-FLPs examined with contrast agent combined with low mechanical indicators contrast-enhanced ultrasound.</p><p><b>RESULTS</b>The surrounding pancreas parenchyma enhancement time, lesion enhancement time, and peak enhancement time between different groups of s-FLPs had no significant differences (P > 0.05), while the beginning to peak enhancement time showed significant difference (P < 0.05). When using the enhancement speed as a diagnostic indicator to differentiate pancreatic carcinoma from tumor-like pancreatitis, the sensitivity, specificity, and accuracy were 90.5%, 71.4%, and 85.7% for pancreatic carcinoma and 75.0%, 91.7%, and 89.3% for tumor-like pancreatitis. When using the enhancement pattern as a diagnosis indicator to differentiate pancreatic carcinoma from tumor-like pancreatitis, the sensitivity, specificity, and accuracy were 85.7%, 78.6%, and 83.9% for pancreatic carcinoma and 75.0%, 100%, and 94.6% for tumor-like pancreatitis. When different indicators were combined, enhancement pattern and enhancement speed showed the best diagnostic results; however, the Youden index was not improved.</p><p><b>CONCLUSIONS</b>Different s-FLPs show different enhancement findings on contrast-enhanced ultrasound. The enhancement pattern and enhancement speed are the most useful diagnostic indicators.</p>
