  2010 MAY 30 - (VerticalNews.com) -- Recently, contrast-enhanced (CE) ultrasound (US) appeared as an important modality to show the vascularity in the areas of interest, and has been used widely in clinical diagnosis of liver lesions. Three dimensional ultrasonography (3D US) allows three orthogonal planes to spatially demonstrate the features of subjects, which has been frequently used in fetal US. Different from the 2D images, CE 3D US acquires the data in a volume of interest (VOI) by automatically scanning with a desired angle and allows reconstruction of tomographic images in three orthogonal planes and renders angiogram-like images. The combination of 3D US and CE US can present the enhancement of lesions in three dimensions and also in parallel slices by multiple-planar visualization. Although many studies on differentiation among various focal liver tumors have been conducted using CE 2D US and recently a few using CE 2D US with Sonazoid, the exact value of CE 3D US with Sonazoid in the differential diagnosis of various focal liver tumors has not yet been clarified ...read more

  2010 MAY 9 - (VerticalNews.com) -- Intraductal papillary mucinous neoplasm of the pancreas (IPMN) shows a wide spectrum of histological presentations, ranging from adenoma with mild atypia to adenocarcinoma. In general, branch duct IPMN develops slowly and has a comparatively good prognosis. However, in several studies, it became evident that IPMN is a disease that very frequently coexists with cancer. Several investigators have suggested that the prognosis of the IPMN is more closely related to coexisting diseases than IPMN per se ...read more

  2010 MAY 9 - (VerticalNews.com) -- Esophageal cancer is one of the most common malignancies worldwide. Its mortality is very high due to relatively late diagnosis and inefficient treatment. The ability to reverse the outcome of esophageal cancer is limited due to a poor understanding of its biology. Progression of esophageal cancer may be associated with sphingosine 1-phosphate (S1P) and its receptors S1P1-5, which play an important role in other cancers. A possible role for S1P and its receptors in human esophageal cells has not previously been investigated, nor has the importance of S1P and its receptors in esophageal cancer growth and metastasis been addressed ...read more
