Question

Quizplus · Accepted Answer

A GI series uses barium to visualize the stomach and intestines. Barium is a chalky substance that coats the inside of the GI tract, making it visible on X-ray images. Ultrasound is not typically used for GI studies, and a fiberoptic instrument would be used for an endoscopy or colonoscopy, not a GI series. Blood tests can provide information about stomach function, but they are not used during a GI series.
