Design outcomes

Primary

Measure	Time frame

Secondary

Measure	Time frame
To evaluate reproducibility of contrast-enhanced harmonic endoscopic ultrasonography(Ex-PHD-THE). To compare diagnostic ability in diagnosing pancreatic tumors between contrast-enhanced harmonic endoscopic ultrasonography(Ex-PHD-THE)and MDCT.	—
