Question

Quizplus · Accepted Answer

Sonography (ultrasound) can be used to detect esophageal varices as an alternative to an esophagogram. It is non-invasive, does not involve radiation exposure, and can provide real-time imaging during a procedure like an endoscopy to guide treatment. CT and MRI may also be used to diagnose esophageal varices, but they are not typically used as a first-line option. Nuclear medicine may be used to evaluate liver function and blood flow, but it is not typically used for directly visualizing esophageal varices.
