Effectiveness of contrast-enhanced harmonic endoscopic ultrasound for the evaluation of solid pancreatic masses

Figure 1 Conventional endoscopic ultrasonography (left) and contrast-enhanced harmonic endoscopic ultrasonography (right). These pictures showed a typical example of a hypoenhancement pattern (A), an isoenhancement pattern (B), and hyperenhancement pattern (C).

Figure 2 Receiver operating characteristic curve. Hypoenhancement pattern, determined by contrast-enhanced harmonic endoscopic ultrasonography, was calculated to diagnose pancreatic adenocarcinoma with the area under the receiver operating characteristic (ROC) curve of 0.799.
