Thoracic region.

Major bronchial collapse is confirmed.

Fluoro useful because the pathological variation in the diameter of the bronchi is related to the respiratory cycle.

Thoracic region to assess the esophagus.

There is no evidence of alteration.

The intention was to evaluate with contrast-enhanced peristalsis fluoroscopy if the esophagus was observed to be dilated, but it was not.

Tracheal evaluation.

Tracheal collapse is discarded (the narrowing of the tracheal lumen is permanent, and, in a collapse, it varies with the respiratory cycle).

Trachea is assessed.

A slight reduction in the cervical tracheal lumen is observed in relation to the respiratory cycle, which is why a mild cervical tracheal collapse is diagnosed.

Fluoro useful because the pathological variation in the diameter of the trachea is related to the respiratory cycle.

Part 1:

Dog swallowing mush with contrast (empty stomach)

Part 2:

Mush with contrast going through the digestive tube and being accumulated in the stomach

Part 3:

Last part of the dog swallowing contrast, which is accumulated in the stomach and initial part of the intestine
