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 کاملDiagnosing Pancreatic Tumors Using Contrast-enhanced Harmonic Endoscopic Ultrasonography with Sonazoid.
Contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) with contrast agent enabled us to assess the hemodynamics closely, despite limited data in pancreatic tumors. We have initiated a prospective, single arm, and non-randomized study to clarify the accuracy and safety of CH-EUS with Sonazoid and time-intensity curve (TIC) analysis for diagnosing benign or malignant pancreatic tumors. A...
متن کاملCan contrast harmonic endoscopic ultrasonography replace endoscopic ultrasonography-guided fine-needle aspiration in patients with solid pancreatic lesions? An American perspective
Contrast harmonic endoscopic ultrasonography (CH-EUS) is a novel form of endoscopic ultrasonography (EUS) that utilizes intravenous contrast agents to characterize the vasculature inside an organ of interest with a broadband transducer that can detect harmonic signals.[1,2] These contrast agents initially played a major role in echocardiography, enhancing the power of ultrasonography to image c...
متن کاملThe efficacy of contrast-enhanced harmonic endoscopic ultrasonography in diagnosing gallbladder cancer
The aim of this study was to review the efficacy of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) in diagnosing gallbladder (GB)-protruded lesions. Thirty-eight patients underwent CH-EUS for the diagnosis of GB-protruded lesions. Twenty-four patients whose major axes of their largest lesions were longer than 10 mm were recruited. The ability of CH-EUS to diagnose malignant or b...
متن کاملContrast-Enhanced Harmonic Endoscopic Ultrasound-Guided Fine-Needle Aspiration in the Diagnosis of Solid Pancreatic Lesions: A Retrospective Study
BACKGROUND The negative predictive value of endoscopic ultrasonography-guided fine needle aspiration for the diagnosis of solid pancreatic lesions remains low, and the biopsy specimens are sometimes inadequate for appropriate pathological diagnosis. AIMS To evaluate the usefulness of a novel method of contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration for the ...
