In clinically suspected esophageal perforations, Hypaque/ Gastrograﬁn used as barium may cause mediastinititis in patients with perforation. Conversely, barium is used to evaluate for suspected aspiration as Hypaque/Gastrograﬁn may induce pulmonary edema if aspirated. INDICATIONS ᮀ Evaluation of patients with dysphagia ᮀ Evaluation of patients with odynophagia ᮀ Evaluation of suspected gastroesophageal reﬂux (the stom- ᮀ ᮀ ᮀ ᮀ ach is not evaluated in an esophogram). g. ) are performed in an attempt to elicit gastroesophageal reﬂux.
The study is often performed to determine if drainage from the intrarenal collecting system into the ureter and bladder is adequate to allow a catheter to be capped or removed. CONTRAINDICATIONS ᮀ Active infection. If there is an active pyelonephritis, pyelitis, or urinary tract infection, there is a theoretic risk of infection spread (including sepsis) by putting the system under increased pressure during contrast injection. LIMITATIONS ᮀ Collecting systems under high pressure cannot be easily opacified and thus only minimal contrast may be introduced into the system.
In these cases, the esophagus distal to the abnormality cannot be assessed. 45 Modiﬁed Barium Swallow This is a ﬂuoroscopic study used solely for the evaluation of aspiration risk. It is often performed in conjunction with the speech pathology service. Patients are administered barium in varying consistencies while the oropharynx is evaluated ﬂuoroscopically. The swallowing mechanism is evaluated for motor coordination, efﬁcacy of the swallow to clear barium from the pharynx, and possible aspiration.
