This case is of special interest because of a connection with Hadwiger’s conjecture which was the motivation for this research; and we deduce a unification and strengthening...
متن کاملTherapeutic endoscopic ultrasound.
Endoscopic ultrasound (EUS) is a viable and often preferred alternative to interventional and radiologic procedures, and the therapeutic applications of EUS continue to evolve. This evolution was catalyzed by the introduction of linear echoendoscopes that provide continuous imaging and observation of needles and by therapeutic devices that pass through large-caliber working channels. In this pa...
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...
