Endoscopic US (EUS), a.k.a. endosonography, is minimally invasive procedure combining endoscopy of digestive tract with high-frequency US of gastrointestinal (GI) wall and surrounding organs and tissues
Sometimes, term EUS is also used to include endobronchial US (EBUS) and intracavitary (vaginal, anorectal) US using rigid transducers (linear and radial)
For contrast-enhanced EUS techniques using low MI, terms contrast-enhanced low mechanical index (MI) EUS (CELMI-EUS), contrast-enhanced harmonic EUS (CEH-EUS), and contrast harmonic EUS (CH-EUS) are in use
