UNASSIGNED: The present study investigated the potential utility of contrast-enhanced abdominal ultrasonography (CEUS), using Sonazoid   , in @entity14 ( @entity14 ). Three @entity1 were subjected to CEUS with Sonazoid   . Surgical specimens were immunostained for @entity2279 . Numbers of blood vessels positive for @entity2279 were analyzed in each of five fields at *400 magnification and averaged to determine blood vessel density. Blood vessel density was compared between non- @entity5 and @entity5 areas. Prior to the administration of Sonazoid   , @entity14 was illustrated as irregular-shaped wall thickening. One minute after the administration of Sonazoid   , the majority of the thickened wall was enhanced, while some parts of the thickened wall remained unenhanced. Blood vessel densities of non- @entity5 and @entity5 areas in @entity1 two were 25.2  2.5 and 5.2  1.1 (P<0.0001). Blood vessel densities of non- @entity5 and @entity5 areas in @entity1 three were 19.0  3.1 and 2.2  0.8 (P<0.0001). Tumorous areas of @entity14 were not enhanced 1 min after the administration of Sonazoid   . Blood vessel density was lower in @entity5 areas compared with non- @entity5 areas, as evidenced by immunohistochemistry for @entity2279 . These findings suggest that CEUS may be useful for the determination of the extent of @entity14 .

Unenhanced areas revealed by contrast-enhanced abdominal ultrasonography with Sonazoid    potentially correspond to XXXX .
