Question

Quizplus · Accepted Answer

Ultrasonography uses high-frequency sound waves to create an image of internal organs, making it the best choice for producing an image of the liver, gallbladder, or pancreas. Magnetic resonance imaging and CT scans use a combination of magnets and X-rays, respectively, and are not as specific for imaging these organs. Radiographs (X-rays) are not very useful in visualizing soft tissue organs like the liver or pancreas. Nuclear scans use radioactive materials and are more commonly used for detecting cancer or evaluating organ function, rather than producing an image of the specific organs mentioned in the question.
