Fluoroscopic studies of the upper gastrointestinal tract: techniques and indications. / Estudios telemandados con control fluoroscópico del tracto digestivo superior: Técnicas e indicaciones.

ABSTRACT

Fluoroscopic studies of the gastrointestinal tract are becoming increasing less common due to the introduction of other imaging techniques such as computed tomography and magnetic resonance imaging and to the increased availability of endoscopy. Nevertheless, fluoroscopic studies of the gastrointestinal tract continue to appear in clinical guidelines and some of their indications are still valid. These studies are dynamic, operator-dependent examinations that require training to obtain the maximum diagnostic performance. This review aims to describe the technique and bring the indications for this imaging modality up to date.
