Contrast-enhanced harmonic endoscopic ultrasonography in pancreatic diseases.

Contrast-enhanced harmonic endoscopic ultrasonography in pancreatic diseases. Diagn Ther Endosc. 2012;2012:786239 Authors: Xu C, Li Z, Wallace M Abstract Endoscopic ultrasonography (EUS) is the most sensitive imaging method for diagnosis of pancreatic tumors. However, it still has limits in the differentiation between pancreatic cancers and inflammatory tumor-like masses. A novel technology, contrast-enhanced harmonic EUS (CH-EUS), has been developed recently. It can visualize both parenchymal perfusion and microvasculature in pancreas without Doppler-related artifacts. Therefore, it is superior to EUS and CT in detecting small pancreatic masses and differential diagnosis of pancreatic masses. CH-EUS could be used for adequate sampling of pancreatic tumors and may predict the pathological features of the pancreatic solid lesions but still cannot replace EUS-FNA now. PMID: 23197932 [PubMed]
