Contrast-enhanced ultrasonography: advance and current status in abdominal imaging
In the field of contrast-enhanced ultrasonography (US), contrast agents are classified as either first- or second-generation agents depending on the gas within the microbubbles. In the case of first-generation contrast agents, a high-mechanical-index technique is used and only intermittent scanning is possible due to the early destruction of the microbubbles during the scanning. The use of seco...
متن کاملContrast-Enhanced Endoscopic Ultrasonography for Pancreatic Tumors
OBJECTIVES To investigate the usefulness of contrast-enhanced endoscopic ultrasonography (CE-EUS) for histological differentiation of pancreatic tumors. METHODS CE-EUS was performed for consecutive patients having a pancreatic solid lesion, and tumors were classified into three vascular patterns (hypervascular, isovascular, and hypovascular) at two time phases (early-phase and late-phase). Co...
متن کاملContrast-Enhanced Harmonic Endoscopic Ultrasonography in Pancreatic Diseases
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 D...
متن کاملContrast-enhanced endoscopic ultrasound.
Compared to other imaging modalities, endoscopic ultrasound (EUS) has limitations in terms of image enhancement. However, with the availability of contrast agents in ultrasonography, EUS has evolved. Contrast-enhanced Doppler EUS (CD-EUS) enhances Doppler signals from vessels and is useful for characterizing lesions detected by EUS. Moreover, contrast-enhanced harmonic EUS (CH-EUS) with second-...

index of 50 was admitted to our intensive care unit with the clinical appearance of severe biliary pancreatitis. Bedside ultra− sonography was difficult due to the pa− tient’s obesity but revealed a dilated common bile duct (l" Fig. 1). Convention− al endoscopic retrograde cholangiogra− phy (ERC) with X−rays was considered impossible due to the obesity. Bedside endosonography (EG 383OUT; Pentax...
