Applications of contrast-enhanced harmonic endoscopic USG on
Over the last decade, the clinical applications of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) have increased steadily. The development of second-generation ultrasound contrast agents has allowed superior visualization of the microvasculature and tissue perfusion of the target lesion. This methodology has proven useful in the differential diagnosis of solid pancreatic masses and lymph nodes. In addition, the applicability of CH-EUS has expanded to nonpancreas structures such as biliary, focal liver lesions, and vascular disease. This article focuses primarily on the novel applications of CH-EUS in biliary tract and visceral vascular diseases.
Contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) is an emerging technique used in many gastrointestinal disorders. CH-EUS has not only improved diagnostic performance in numerous pathological conditions but has also changed the status of EUS in some gastrointestinal disorders. Innovations continue to expand the capabilities of CH-EUS and push the boundaries of its indications.[1] This review focuses on new potential indications of CH-EUS.
