  		Fig. 1. —Graph shows contrast index of pancreatic tumors with dynamic sonography. Tumors are listed by type of disease, number of tumors, and contrast index (mean ± SD). IPM = inflammatory pancreatic mass, ICT = islet cell tumor, SCA = serous cystadenoma, SCT = solid and cystic tumor.

  		Fig. 2A. —66-year-old man with pancreatic ductal adenocarcinoma. Graph shows time—intensity curve of pancreatic parenchyma (a) and tumor area (b). At 42 sec after contrast agent injection, intensity had maximum enhancement in both tumor and parenchyma.

  		Fig. 2B. —66-year-old man with pancreatic ductal adenocarcinoma. Sonogram obtained before injection of Levovist (Schering, Berlin, Germany) shows hypoechoic mass lesion (arrows) in head of pancreas.

  		Fig. 2C. —66-year-old man with pancreatic ductal adenocarcinoma. Dynamic sonogram obtained 42 sec after contrast agent injection shows intensity of parenchymal area is slightly increased but intensity of tumor (arrows) is not increased. Contours of tumor became clear.

  		Fig. 3A. —74-year-old woman with nonfunctioning islet cell tumor. Graph shows time—intensity curve of pancreatic parenchyma (a) and tumor area (b). Intensity had maximum enhancement in both tumor and parenchyma 37 sec after contrast agent injection.

  		Fig. 4. —Chart shows contrast enhancement of pancreatic solid tumors imaged by dynamic sonography versus dynamic CT in 43 patients. In 93% (40/43) of tumors, grade of enhancement on dynamic sonography was closely correlated with grade of enhancement on dynamic CT. • = adenocarcinoma, {circ} = inflammatory pancreatic mass, {blacksquare} = islet cell tumor, {square} = serous cystadenoma, {blacktriangleup} = solid and cystic tumor, {triangleup} = metastatic tumor.
