The feasibility of contrast-enhanced endoscopic ultrasound in the assessment of tumour vascularisation in digestive cancer patients

Background: Endoscopic ultrasound (EUS) is currently considered the method of choice for the early detection and tumour staging of digestive cancers, with a better accuracy as compared with computer tomography and magnetic resonance imaging. Due to the unavailability of contrast-enhanced harmonic examinations, there are other accepted techniques (contrast-enhanced power Doppler) for the assessment of tumour vascularisation, even when artefacts appear (moving artefacts and blooming). The aim: The study included 30 consecutive patients with various digestive tract masses: eso-gastric cancer, gastrointestinal strom…
