Contrast-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-...
متن کاملEndoscopic ultrasound elastography
Endoscopic ultrasound (EUS) elastography is an imaging procedure used for the visualization of tissue elasticity during usual EUS examinations. EUS elastography can be accomplished real-time with state-of-the-art ultrasound systems, with the images being represented in transparent color superimposed on the conventional gray-scale B-mode scans. The aim of this review was to introduce the potenti...
متن کاملEndoscopic Ultrasound (EUS) Elastography
2007〉 Recent developments in ultrasound (US) data processing have made it possible to develop new software. The latest generation of US workstations incorporate a central computer allowing very precise processing of the US image. This has made possible the reconstruction of images like three-dimensional US, second harmonic imaging for detecting contrast agents following intravenous injection, a...
متن کاملEndoscopic ultrasound in the diagnosis of acinar cell carcinoma of the pancreas: contrast-enhanced endoscopic ultrasound, endoscopic ultrasound elastography, and pathological correlation
We report a case series of five patients with pancreatic acinar cell carcinoma who received surgical treatment and compared the preoperative contrast-enhanced endoscopic ultrasound (EUS) and EUS elastography patterns with the surgical specimens. The contrast-enhanced EUS indicated vascular tumors with gradual enhancement in four patients and a hypovascular tumor in one patient. The elastography...
متن کاملGastrointestinal imaging: endoscopic ultrasound.
The development of endoscopic ultrasound (EUS) since its introduction in the early 1980s has added greatly to the quality of imaging of the gastrointestinal tract. EUS is probably the investigation of choice for local staging of several gastrointestinal tumors and evaluation of submucosal masses. In addition to well-established indications, newer applications of EUS are emerging. For example, E...
