Which diagnostic radiology exam is commonly used to diagnose upper GI diseases?

Fluoroscopy is commonly utilized in diagnosing upper gastrointestinal (GI) diseases due to its ability to provide real-time imaging of the GI tract. This dynamic imaging technique allows healthcare providers to observe the function and movement of the upper GI structures, including the esophagus, stomach, and duodenum, while a patient swallows a contrast medium, such as barium. The continuous nature of fluoroscopy enables clinicians to assess motility issues, structural abnormalities, and the presence of obstructions or lesions.

In contrast, while X-ray imaging can also be used in upper GI assessments, it provides static images that may not fully capture the functional aspects of the GI tract. CT scans are highly detailed and effective for evaluating various pathologies, but they are typically more utilized for complex cases and less for initial evaluations of functional disorders. MRI, while excellent for soft tissue imaging, is not generally the first choice for examining the upper GI system due to factors such as cost, availability, and the need for specialized patient preparation.

Overall, fluoroscopy is preferred for its real-time observation capabilities, making it the most suitable exam for diagnosing upper GI diseases.
